I've been doing a little work to my truck and was wondering if the last step would be worth the money..... I have....
2004 Silverado 2500 non HD
Gibson cat back
Airaid box
90mm (silver) Tb
Ls9 cam and springs
Tvs1900
3 inch pulley 9-10 psi
The tuner says I'm out of injector... I have not dynoed it. The tune is safe now but he says i could get more out of it if I went to 50lb injectors. I was thinking of getting some American Racing Headers to go with it.. Do you guys think it would make a substantial difference by doing the injectors and headers? I guess I have a crap load of air and fuel going in... It should make sense to get more out, right? Any idea on power gains by doing the last step? Thanks.... Let me know what you think.

 

Do you have stock injectors? Hell you should injectors with any FI. Headers will help but you might want to pulley down to keep boost up.

 

I called Magnuson and I have 43lb injectors that came with the supercharger kit.
