Hi Guys

I own a EVO 6 GSR and recently built my engine with Stroker comp pistons, rods and a stroker crank bringing the CC to 2.4Lt.The cams are Blitz light weight with a little delayed lift.The ECU is a Reflashed evo 8 ecu with a carbon copy Ralliart program.The turbo is standard evo 6 with standard wastegate.

The problem is with the Apexi AVCR i am only getting 1.2 bar boost on 1st and 2nd gear and 1.5 bar boost on the rest of the gears.Can somebody help and tell me how i can increase the boost to spike to max boost and then taper it down.When the vaccum hose is removed and we do a run max boost is 1.7 bar

Also the AVCR is showing a negative boost when the engine is switched off and on ACC mode.

Can somebody advise pls

Thanks

Chris

 

maybe a small wastegate leak? what is the AVCR set at?
