I'm gonna call BS on that time. So you are saying that you've picked up over 1 second on a stock 2dr 2wd truck with your mods??? What was your trap speed? How about your 60' time or 1/8th time/speed?
My Bonneville with more power (240hp stock), about the same weight, and more torque (280ftlb stock) only runs 14.84sec in the 1/4 for my personal best. I highly doubt that you've picked up 50hp and 30ftlb with a PCM and trans work...
Maybe 30 at best... Whats the programmer good for? 20 would be generous.

Now, trans work, while shortening and firming up shifts, it will not increase the performance of the vehicle. It will result in less wear on the clutches, but not lower the hp loss through the transmission.
And some of the best all-in-one PCM programmers are good for maybe 15hp, 20hp MAX. A custom burn may yield 25hp TOPS, but with no other mods, you'd be hard pressed.

Now, firming up shifts might improve the 1/4 mile times SLIGHTLY without giving any horsepower, but would mostly serve the purpose of saving the transmission right? 14s??? in a Blazer? Im not sure who would want to let alone claim to be able to...

call all the bs you want. i have a custom trans. no simple mods like a lot of people run. i have a custom servo not a corvette one. it doesnt shift out of 1st till 40. and other trans mods. i have 3.42 rearend. as the the pcm its a custom tune not a programer. and with the trans work we were able to squeze a couple more #'s out of the motor by adjusting the trans electronically. plus when i race i run a smaller tires in the rear for added traction and to give it a little more gear. Some of you people need to put your calculators away and learn to feel a car. ive learned that, cause every car is different even tho they are supposed to be the same. any way back to the subject its not bs lol 
Good, then back it up with a dyno sheet and a timeslip... thanks...

Again, servo's/shift-kits/etc do not decrease the hp loss through an automatic transmission.
You come on here and your first post is bragging about a 14.7sec - 1/4 mile when we have a nitrous blazer (02 Vortech) using a progressive 100 shot nitrous system running 9.29sec - 1/8 mile which translates to about a 14.31sec - 1/4 mile. That's with 100shot of nitrous! Not just a tune with no supporting mods. The gears will help... some... But still haven't accounted for a full half second of ET. Again, what was your trap speeds in the 1/4? in the 1/8th? Your 1/8th time? 60' time?
Looks like someone took their expected hp and curb weight and threw it into an online calculator to me. Until slip(s) are produced, I stand with my BS call.

Actually, let me retract my gear ratio statment. At 3.42, you're ratio is higher than my Bonneville (with 2.93) true, but unless you've picked up more than 50hp and 30lbft (which L67 motors are notorious for being underrated by GM), you are still behind me. A 3.42 is actually one of the worst ratio's found in a stock 4.3L blazer for 1/4 mile times.
You are sticking to your guns with that trans too... So what exactly did you do to it? Unless you changed the internal gear ratios, you haven't changed things that much to improve your times noticably. And as far as I know, there isn't anything available to change these ratios internal to the trans... Not to mention that a rear gear swap to say a 3.73 or 4.10 would have been much more cost effective and would have yielded better results.
And yeah, the 4.3L has good low end grunt, but at the expense of anything high end unless you do significant work to the motor to improve it's flow (which, in most cases, hurts your low end power).
But I'll ask again, what were your trap speeds in the 1/8th? and 1/4? How about your 1/8th time? 60' time?

So that guy never did come back with a timeslip did he?

In another thread he went to the track and only made one run. 0.6xx RT with an ET of 15.8 something at 84mph and a 2.2sec 60' time. He said he spun through first gear and into second, which doesn't jive with his 60' time.
