I have apoweraid TBS , it makes a whistling/turbulance noise below 2000rpm. It doesn't fit well with the K&N FIPK. Makes the hood bulge up a little. I Have Granatelli MAF on it too.
These items were usd on 3 Blazers now and I think it breathes easier.
Horsepower is expensive. I would read up on other folks testimonials. My opinion on it is it's not a much needed item.
I got it through JC Whitney.

I could make that same thing (without the stupid swirl) for probably around $50 for the complete kit. The only thing that swirl does is create that whistle. Nothing more. Throttle body spacers do work if what you are looking for is more low end torque at the expense of high end torque/power.
I designed and sold TBS kits for Dodge 3.5L & 3.3L v6s and typical gains that I saw through customer reviews of my spacer were a nice kick in the pants off the line and 2-3mpg increase in mileage on the 3.5L and around 1-2mpg on the 3.3L. Not bad for a $50 expense.
The hardest part of these spacers is milling in the o-ring groove. There isn't a paper gasket made for this throttle body.

Is it normal to have a thin layer of oil baked to the underside of the throttle blade?
My intake manifold is wet with oil, and it creeped up to my TBS.

That oily layer is from the EGR valve and it is just combustion by products. It is normal for todays engines with Exhaust Gas Recirculators (EGR).

It's a sloppy design. I noticed today my Impala 3.8 litre (or liter) has oil on the IM too.

Pretty much any late model vehicle (from like '90 on) has this problem. It is a direct result of the EGR system which is there to reduce the NOx emissions and does a very good job of it too.

speaking of EGRs, My Impala failed the first emission test it had last year and they said it was the secondary air pump and EGR valve.
I got aquote of the EGR at a dealer and it was over $300.00. The parts guy said to get a 2nd opinion and I did. It threw no codes and I didn't need a thing. I think I'll be going to the latter shop for state inspections.

Back to the trottle body spacers. Don't waste your money. GM spent millions designing it into your engine, its called Vortec. All 4.3L engines are vortec's.
