I have a 98 12valve auto, was 180hp stock. I am running a #5 plate,honed 370's,191dv's,BHAF,HX-40,full 4" exh, water/meth,15.5*, TCS convertor and built trans. 38lbs max boost, I am having trouble with egt's, can hit 1600 when i pour the coals to it after convertor locks, when i pull my 30 foot camp trailer I have to keep an eye on pyro, runs about 11-1200 at 60mph and dont dare stuff my foot to the floor after trans locks. exclude the water meth as it is still not finished. I am building a custom intake and will install nozzles in it then system is done.

 

i would say high 300 maybe
