What to expect from a 80MM TB
Hey you experts, what should I expect from installing a 80MM Throttle Body on my 5.3 truck? I'm already modded w/ cold air, engine-back custom exhaust, MAF, Nelson Tune & Shift Kit.
Is it worth it? Will I feel the diffrence?

I put mine on my truck when I had a lot of bolt on's and I think it actually hurt performance. So I took it off and put my spacer back on and it felt stronger again. but when i went with the Procharger I had them put it back on.

if you're not flowing enough air to make the stock throttle body be a restriction, you're wasting your time and money. at the power level you're at, you'll likely lose more than you'll gain.

Just keep your stock TB. Unless your going to install a twin turbo kit or equivalent forced air induction.
The stock TB has plenty of CFM of flow to handle most power adders as well.

before i had nelson tune for the bbk 80mm t/b i lost 4/10 of a second at the track, but after we tuned for the t/b i gained 1/10 and 2mph over stock t/b. Same night testing.
On the dyno it showed 10hp gain. But like i said after nelson tuned for it.
