Does anyone know how much hp I could get w/ bigger injectors and a bigger throttle body. This would all be complimented by another pcmforless tune. I have all the mods in my sig, would injectors and tb compliment the mod's? Also what brand of each should i get or whats the best deals youve found.thnx for the help.

 

Unless your current injectors are not feeding enough fuel, larger injectors will offer no gain.

58mm TB will probably be worth 5-10 hp.

 

Agreed.... you won't need larger injectors until you go over 400HP, and you aren't there yet. Putting 30#'s in at this point will simply lower injector duty cycle, not increase power. Whether you would see anything at all with a 58mm TB is open to debate. I've seen dyno tests on 58's that lost 10HP on a stock setup. Why go to the bother of opening up the intake manifold for a 58, when you could use a 52, or the AS&M 54mm TB?

 

Thanks I was just curious.

 

I was told a 58mm throttle body shows improvement on part throttle acceleration being more crisp but no WOT improvements unless your engine is really needing that much induction with some wild setup.
