Running rich!
So few days ago i was out data logging and my car was running spot on with 11.0 afr when all of sudden i felt a loss in power, i seen that my afr gauge was showing im running 10.0 pegged out and when i came to a spot it was still pegged out at 10 for a min till it went back up, iv cleaned the maf n map sensor, also torque down sc to spec. The car will run normal for the first few pulls and then it pegs rich again. I didnt have any cels so this is what is worrying me

Meaning that the wideband will lean out to 11.0 afr as i near redline, this is just the first revison of the base tune and the base tune was not doing this.
Ill try that thanks.
how do u check a narrowband, and what sensor is considered the narrowband?

Narrowband has nothing to do with wot afr. Wot engages open loop fueling
Unless op, just to clarify... Are you saying your cruising or idling and go from around 14.7 too 10.00, and back to 14.7
Or your going wot, hitting 11.00 then after a couple pulls pegging 10.00 afr during wot?

Ok i will try and explain this better but its basicly the second choice u said 100% meth, when i go wot i hit 11 afr, after a few pulls something happens and when im wot I hit 10 afr pegged out, when this happens if i pull over my afr willstay pegged at 10 for a min and then start to return to the normal 14.7 idle.
