Doesn't support 05? Did you get that from the HPTuners site?
It's generaly the older one's they don't suppport (LT1) ect.(97down)
Maby I should specify how the "Credits" work.
Once you register the truck (example my 98) I can tune my 98truck as many times as I like. (Unlimited)
If you add another vehicle... 99WS6Transam... or any other.. you can tune it unlimited.
Each vehicle requires 2 credits.
The program comes with 8credits. (4vehicles) (unlimited tunes)
When you go for the 5th vehicle you'll have to buy 2 creidts (99.00) And so on when you add vehicles.
Hope that explains it better.
First thing We'd need to address on any boosted truck is the timing.
And move up the Power enrichment under heavy load.(boost)
Be glad to help,
Scott~

Just contacted a administrator at HPTuners.
He said he should be able to do your 05 ECM.
Contact him at: Bill@Hptuners.com
You can discuss what your truck is and what you'll need to do
to have it directly supported.
I could not scan a 08 Durimax Diesel the first time.. sent him the vehicle scan file
and in 2days I had a Beta Version to read and tune the truck.
Sometime's it's contacting the right people with the right questions :)

I'll have to fire off an email after I get a little sleep in...
My main reason for a tuner program is to get rid of that horrible RPM holding feature, lol.
I pull it out of gear and it takes 2 seconds or so before the RPM's start dropping...

Hey great looking setup Scott. I had a question for you about the Walbro pump you used. I know you have a part number off the box the pump came in, in one of the pictures. But, I was hoping you could tell me weather or not the pump is a Walbro F20000169 (actual Walbro #)?
Thanks,
Eric
I don't know if this is the best spot for me to add this but, I've been talking with a fuel injection shop and they tested the newer V6 fuel spider (I'm guessing the V8 one would be the same) for me on an ASNU flow bench at 80% duty cycle and adjusted the pressure with the regulator and these were the results:
Stock opening pressure was 60 psi and regulator maintained 65 psi at 22.3pph flow.
Then they increased the pressure. 70 psi - 23.5 pph 75 psi - 24.7 pph 80 psi - 25.1 pph 85 psi - 25.5 pph The regulator would not continue past 85 psi

That is either the part number right from Warbro or the part number that Full Throttle Speed and style uses. I'm not sure. It's for a Buick GN. 225lr/hr pump.
Any other GN kit should be similar if not exactly the same. I think they are 95.00.
Thanks and hope that helps,
Scott~

The stock '96+ manifolds will hold around 10psi of boost. If you aren't doing anything to the bottom end, that is probably as much as you should run. Over 10 psi and you really should be looking at lowering the static compression ratio of the bottom end, a different cam with more overlap to take advantage of the pressurized intake, and a new solid intake.
As the typhoon engine had perpendicular intake manifold bolts, the manifold from the turbo motor will not work on the '96+ SCFI motors as their intake bolts are vertical (not perpendicular to the sealing surface).
There is another thread that shows an aftermarket intake for the 4.3L that can be used for turbo applications. Let me see if I can find it.
*EDIT* - Here ya go:
Bad news... Good news (Turbo Build)

If you decide to use a Sy/Ty intake you'll need to pull the heads off yours and have the "Old" style intake pattern drilled and tapped for the Sy/Ty manifold.
The lower Sy/Ty intake will also need to be welded on top/bottom of the intake ports since the vortec heads are taller/deeper than the stock sy/ty heads or L35's.
A Marine intake bolts right on. There's some small work when changing it over but very simple and can be purchased for 250-400.00.
Elderbrock intakes will work also. But need bungs welded in for fuel injectors and rails setup..
Those are your simpler choices.
Your stock intake can handle the boost it's just that your fuel system won't support much more than 10psi. (volume of fuel) (as stated above by swart)
There's guys that nuked their stock Sy/Ty engines and got a junk yard vortec style motor and have had great luck with them. ... I agree the pistons are not as ideal as a stock Sy/Ty piston but that only becomes a factor with detonation. A good tune with no knock retard/detonation issues and your ok.
Hope that helps,
Scott~

Wow! Great information! So, all i'd have to get is the Sy/Ty Turbo Manifold, a turbo, all the oil lines and such, charge piping, intercooler, and something such as HPTuners to tune for fuel and no knock?
Now, you're saying that around 10lbs of boost is what the stock injectors will hold up to right....of course with a tune that is?
All i'm wanting to have is about 8-10lbs of boost, will my stock motor hold up to that? I've got 64,000 miles on it and have had the oil changed every 3k miles...i haven't dogged on it much at all because the darn things so slow, it's pointless to get on it.
I surely do appreciate the help fellas and i'm sorry if i'm being a pain!
One more quick question...
Would a T3/T4 turbo be sufficient enough for this build?

If I were you I'd choose the Marine intake or the Elderbrock intake. The Sy/Ty intake is too much trouble.
Your stock engine would easily support 8-10psi.
HPTuners is what you'll use... Definatly.
If you pick up stock Sy/Ty exhaust manifolds/cross-over you can choose from a wide selection of turbos that bolt right on. Bolt on downpipes (stock or other) So that's the easiest route there for sure.
We have 146,000+mi on our stock engine now.. still doing great!

scott, i will be installing a marine intake next weekend. picked up a new one off of ebay for $200. my question is what line on the marine intake is the return line from the regulator? is it the top or bottom line? i am changeing to a marine intake due to to many problems from my stock injection system and my stock regulator. i will also be fabbing up a rear mount turbo as soon as i get done collecting all the parts that i need. thanks for your help.

Congrats!
The larger (3/8s) line is the inlet from the pump. (fuel feed)
The smaller 5/16th line is the return to the tank.
Remember to use your stock throttle body and tweak the lever for the cruse controll to clear the fuel rail.
You''ll need to make a gasket for the throttle body or buy one for a LS1. I think they are the same size and pattern.
The wire colors/hook-ups are on this site and this thread.
If you get stuck e-mail me UR50SLO@aol.com
I''ll get you my phone number so you can call if you need that.
Thanks,
Scott~

thanks for all the help. i have everything else figured out so far(i hope). i have a roll of gasket material that i plan to cut for use on the TB. i dont think that i should have any problems on the rest. as far as my EGR, it is no longer on my truck, and i had my ecm reprogrammed by wait4me. i am trying to get all the parts that will be required to do a rearmount turbo(yes i will take pics). i hope to have everything for the turbo in a few months. i was not aware of the cruise control bracket needing to be modified, so thanks for the heads up. i was the one that asked you for the wire hook-ups/colors ealier in this thread. thanks again for all the info.

I''ve got nothing against rear mounts. They are simple to hook up and effective.
No problem on the info... sure should help save some head scratching and time when it comes to someone else doing the same process.
Good luck with the swap and if you need somthing let me know. :)

If I didn''t bury my truck to the frame in mud, a rear mount would work

Finally got some "alone" time with the Jimmy today.
Went through and changed spark plugs/wires..... Changed the oil and filter.
Plugs looked awsome. I changed them anyway. R42LTS gapped at .33
I think the wires were OEM since they were numbered. I thought I''''d changed them
before but I might not have. I''''ll need to get a new cap this week.
I tuned it some more. Added some timing in places and took some out in a few.
Added some more fuel in PE (power enrichment)
Getting consistant 11.7-11.5 AFR on the wideband at WOT with no knock at 11psi.
The intake air temp driving around is about 10-15deg above outside temp. I''''ve got
the temp sensor just before the throttle body so it''''s seeing close to what the
engine sees. That way I can retard the timing in another table if the IAT get''''s too
high.
Moved the shift points a bit higher as I''''d backed them off to begin with.
All''''s working well. Oil was clean and full when I changed it.
Hope more of you join this soon! It sure is a blast to drive!

thats not too lean? i thought that 14.7 AFR is what you want.

On a wideband O2...
The lower the number the Richer it is.
The higher the number the Leaner it is.
The ECM will try and target 14.7-1 Actuall AFR.
The stock Narrowband''''s are only accurate just above and below 14.7.
That''''s why everyone is switching to having a wide band since it is more
accurate over a "wider" band than your stock O2''''s.
For a boosted application..... every engine and combo is different but
Most tuner''''s target 12.5 to 10.8 AFR. The Jimmy seems happy with mid
11''''s and it''''s safe there.
My Nissan hates leaner AFRs. Anything less than 10.9 and it''''s not
making as much power... Noticably not as much. Weird but true.
So it''''s nice to have all the new tuning tools to help guide you into
power with economy and reliability much quicker.
Thank god the carberator is dead... but it did teach
me to use all my senses when tuning a car. ;)

. The entire top portion from a cyclone or typhoon, should fit onto our 4.3l motors right? If thats not right, the Turbo manifold will right?
