What can i expect to gain power wise by adding one?

 

What other mods do you have?

The throttle's not really a restriction point until you've already got a good intake, header, exhaust, and intake manifold and are running some cams.

 

i have been wanting to do the same thing with my LS, (94) but am still holding back cause no one can really show any gains in the LS, at least no one i have talked to. They say gains start to happen when you port match the intake manifold to the new TB size. That allows for equal and increased flow throughout. However, i dont see who a small increase in TB size wouldn't bring small gains for someone with the basic bolts-ons.?????

anyone???
