pump shop will take it 10% with no issues, how many hrs on machine, have valves been set, injectors replaced, anoroid working on turbo, return line check valve there is a update, email in profile, send me your number, scott.
my guys always used a boost gauge. and a fuel pressure gauge. theywill put out a lot. my last 2388 which was a 1998 had 350 easy. maybe more. when she gets up to 30lbs of boost you will know it. i think they used to put it in 3rd and shove the hydro ahead, to check it. be sure everything in good shape inside if your going to give her a lot of smoke.
How do you plug the wastegate ? Just remove pipe & install a bolt and what do you do about the rest (the anaroid valve) blank it off ? I have a 2188 and feel it may be lacking a bit, but it does smoke a little now
