My R33 Gts-t S2

[mr33gts-t]

hey i got a R33 S2 had it for a year and a half got intercooler exhaust and had a vg30 turbo put on it as i blew the old 1 up, i dunno if they are a better turbo, i finally got a profect B II controler and had it on the dyno and it would not go more thank 10 psi before it spike to 20psi plus then cut out i have splitfire coilpacks new spark plugs even a HKS fuel cut defender, now i cant run any boost other than standard so i have to turn controller off or it just shhots up past 20psi.

sensers are all clean, the mechanic said it can it could be something to do with the turbo the gate staying open or something not to sure exactly wat he said i just want to make my car quicker but dont have alot of money to spend, so if i do need a new turbo is there any good upgrades or ballbearing turbos or something that i dont need a computer for as i can not afford to buy a computer and tune it as well as a new turbo.

hope someone can suggest something cheers Aaron
