Single 17.2PSI boost run:









Multiple runs:







My 1991 Nissan 240sx S13 with SR20DET got dyno and here is the mod list.

Engine:1996 SR20DET Blacktop w/ Garrett GT2871r .64Apexi 1.2mm head gasketArp studsTomei 256 camsBrian crawler springs, retainersCp pistons, rods

Fuel:Nissan oem 740cc injectorsWalbro 255 fuel pumpSard fuel regulator w/ gaugeSplitfire Direct Ignition Coils

Breathing:Z32 n62 MAFApexi power intake filterGreddy intake pipingGreddy VSPL intercoolerHKS SSQV BovGreddy intake manifoldFullrace exhaust manifold (bottom mount)Garrett dump pipeMegan test pipeRSR Ex-mag

Drivetrain:DSS aluminum driveshaftToda lightweight flywheelExedy 3 puck clutch

Electronics:Blitz SBC id boost controllerApexi PowerFC with commander

Questions:

1) Are my dyno curves look good?2) If I set the boost controller 0 boost, it means stock boost right? Then, I should have 6-7 psi for stock internal wastgate for Garrett GT2871r turbo. Then why the chart show 0 psi (3rd pic of the "Multiple runs")? 3) How do I correct the 10 psi boost creep shown on the 3rd pic of the "Multiple runs"? Should I set the gain on the boost controller differently?

Thanks!
