I have a itr motor with full exhaust, & comptech cai. Would it be worth it to change my throttle body, or will i get no gains from it, since my motor is still pretty much stock?

 

I haven't tried it, but I doubt if you'll get more than a marginal increase. A larger TB would/should be one of the last things you try.

If you know anyone with a lathe they can taper bore your TB and increase throttle response with perhaps a 2-3 hp increase (same as Spoon TB).

You might also be a good candidate for an AEBS intake manifold
