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???:wtfsign:

P0725 lists as engine speed input circuit. What's causing that?:wtfsign:

Are these code pretty bad? I just got tuned then did some spirit driving, after that all these codes shown up. I didn't have problems before the tune. I can't clear these codes with obd scanner and even flash back to stock, those codes didn't go away too.
Do a dealer visit necessary?

My friends 2010 MR keeps throwing a p35B8 code and I cannot find any information on this diagnostic code at all. Does anyone know what this code is for?
Re-read the code in EvoScan 2.8

Hello everyone! My 09 MR is throwing a P180C code...I read what is it in the original post but I am wondering if anyone can shine some light on this for me before I make any decisions on what to do next with it. Seems like the previous owner didn't know what he had on hand and seems like he did not perform the correct maintenance on it. Any help will be VERY appreciated...thanks!
