Need help please. 7mgte

[Toyota1]

Hey there all, i'm new to this forum great forum by the way.

Well here is my situation. I have just finished my rebuild on a 7mge. I put 7mgte pistons in chrome rings,new big end and main bearings, 7mgte injectors, also i'm runng around 9 psi boost, Now the problems are. it blows alot of soot under boost and at idle some times, uses fuel like it's going out of style. Any ideas on what to do like 7mgte ecu or ???????

Thanks heaps.
