I have a r32 with a rb25det series 2! I live in whittlesea, I'm looking for a good shop to take it to close to the whittlesea area?? I just dnt think it is running properly?? It sumtimes stalls wen I accelerate and then brake? It missfires sumtimes wen ihave it on high boost setting 11psi?? And just wondering if I need to change the diff cause I kept the r32 diff and i think the ratio is wrong, at 100km/h it is reving at 3000 I think that's too high and it is spoiling a lol bit, and probly useing to much fuel?? The mods I hav are rb25det s2 with rb25det box, big fuel pump, fuel reg, front mount, pod filter, full 3 inch exhaust and hi low boost controler 11psi on high and stock boost on low! Thanks. I should add that whittlesea is in Vic and its kinda near epping
