So I was enjoying my FEMTO unlocked Stage1 E30 BM3 tune giving me 22psi for several weeks. Then I decided to install xHP and reenable the OEM "torque patch" in my BM3 tune allowing proper torque "handshaking" between DME and TCU. And now I get way subpar performance. I'm dealing with 100*F ambient temps even at 10pm at night, but surely that can't have this big an impact on performance...?

Before xHP: bootmod3 datalog - Stage 1 E30 octane
After xHP: bootmod3 datalog - Stage 1 E30 octane

Any ideas here? See anything in there that would indicate why such low boost/torque? Anyone else ever have this?

Not a Corvette.
Car is in limp mode. I don't think there is a need to do that torque limitation change with BM3, as it already has it enabled. You basically turned it back on.

I have both BM3 and XHP. No torque limitation and have logged over 750nm.

Oh wow how can you tell it is in limp mode? Is there an actual indicator in the datalog?

I meant this option in BM3:

How do you have yours set?
