i just put a vortech s trim tuner kit on my auto 03 gt bone stock other then the vortech i used 42lb injectors and a walbro 255 went to dyno for custom tune xcall 2 made 318hp and 324 tq at 8 lbs my question is what are the next mods i should do i would like about 360hp any advice would be appreciated thanks
I would think that you would get more than that...
Is the lack of other mods responsible for the 318?
no, that's about right on. he'd get another 10 or so from catback + midpipe, another 6-10 for 75mm tb/plenum combo, another 10-15 for an AFM powerpipe. he's about at what he should be for a non-cooled, non-bolton GT with a vortech.
