The stock front mani is holding every 3800 back. It sucks. Get rid of it.![]()
Mods are Ct turbo kit, A2A IC, 1.9 rockers, 3" mandrel exhaust, 42# injectors, DHP tuner, I have more im just drawing a blank. Im putting down 412whp so im thinking that mannie is killing me at this point. My last GTP was 390WHP and I had headers on it (but it was a GEN 5 IC set up)
