Just loaded a new tune from pcmforless on my car.

Now I get this DTC code from Datamaster.
"MALF 83: TCC Control Feedback Fault"

Anyone know what causes this code?

I have noticed in the past with my old tune from madz28 that at highway speed my rpms where way to high. After looking at the rpm/speed chart I was cruising like I had 3.73s which would be cool, but I only got 3.23s in the car.


Are these things related in some way?


I never got this code until installing the new tune by the way...

 

Come on someone must know what this code means and what causes it...

DTC 83...
