LOL not sure the guy above me is serious or not, But WHERE did or WHO told you, You had to over spin the Stillen Sc to make the advertised power, That is a BS statement, Their tune is the issue, My kit out of the box 9-10 PSI made 412 WHP, Advertised power,, Just make sure you have the facts right, GTM is a good kit, Still not sold on the MAF location ( Heard some things from some tuners)- I have seen 1 Stillen boom story and that guys was running headers( Not recommended) and a handful of GTM boom stories,
If it where me, I think a changed my mind from before and would have went the way I did, Stillen, Carb legal and will make good power. Myself and EVOkiller are push these to 500WHP or trying anyway, LOL
