So I still haven't been able to finish my car up sadly been working a lot, but my tuner thinks I'm only gonna put down 430rwhp and I just want some opinions cause I think that's ludicrous talk! Mods are (stock cube 6.0,stage 2 243 heads,polluter v2 cam,mms ported msd intake,102mm warr throttle body,100mm maf,1 7/8 LT with hawks sinister 4 inch exhaust,lvl 2 performabuilt 4l60 with fti 4000 hard hit stall, quick performance fabricated 9 inch with 3.70 gears. All umi parts unter the car and viking coilovers on all 4 corners) I was hoping for at least 470rwhp and to trap 125 but idk lol any thoughts or opinions?
