i have a stock 5.7L Vortec engine so i don't think a custom tune would change much of anything.your money would be better spent with a custom tune
Yup, wish I had gone with a tune instead of my Outlaw Power CAI (which is an excellent choice BTW, although you have a 5.7 which I used an AEM Brute Force on and I like also).your money would be better spent with a custom tune
:word: you can get a tune from Wait4Me for about the same price as a CAI and get more out of ityour money would be better spent with a custom tune
