Any guesses on new gains ?
I had an ls6 intake with ported TB and switched to a FAST90 Nick Williams TB. I also and a Meziere EWP.
I have a 234/240 .627 .641 112 lsa cam.
I couldnt even really hear the lope in the cam before, now I can. How much do you think I gained? It needs to be re-tuned as well.
