2010 camaro procharged

[rubbersidedown]

codes 121 & 068 keep coming up (only after WOT 5000 rpm), also get rich bank 1 & 2 no matter what I do with inj slopes & such, LTFT will be stable for multiple drive cycles (+/- 5) then it seems after driving hard, the LTFT will all of a sudden get to -25 & start triggering CE light. Car is stock w/ D1 procharger (9psi) and 63.5 lb injectors. Little assistance would be appreciated. I changed all the anticipated airflow tables and inj scaling and (B4001 & B1213) to tune with the maf, but I can't seem to get it to be consistent. All seems fine til I get into heavy boost, then it gets mad. Do I need to do a 2 bar and virtual VE tune or can I get it properly done with the MAF?
thanks

You probably want to disable the LTFT until you get your fueling sorted out because -25 could be dangerous with boost.

Set:
B1508 to Max (493 F)
B1509 to Min (-40)
B1510 to a value higher than the supercharger can reach

I'm in the process of putting my 2010 Camaro together with a Vortech.

For p0068 check C0803, C0805 and C0806

got part throttle fueling figured out ( ithink) but still get a 121, 068 @ WOT about 5200. 803, 805 are at 512 (max) and 806 is set at 256 @ 100 and upscaled below there... Power reduction mode seems to come on when the 512 limit is reached...

I have a problem with P0121 as well I'm relating it to the surge from the bypass valve the code is a TP sensors 1 and 2 performance, unless someone knows different.
