I'm throwing codes P1870, P1871, U0100, P0725, U0141, C1472, C216E
After bolt on +E85 mod's on my 2010 SE.
I believe the P1870 and P1871 are due to overboost (running 28PSI) on stock turbo. And I have felt some clutch pressure release on WOT at peak torque. Correct me if I'm wrong but lowering boost to 27 PSI should fix this yes?
Also is there a way to increase clutch pressures with a rom patch to correct the clutch slippage?
No idea what the C1472 and C216E is???
P0725 lists as engine speed input circuit. What's causing that?
