So last weekend I went to the drag strip and everytime I got above like 6000-6500 rpm's the car would just lose power and stop pulling hard. Car was running super rich during and after each pass for a few mins. Got a code for P0103 and P0172 after this happened but I think the MAF is fine. Any Ideas? Car is stage 2 with 2.9 and 60s.

sounds like you ic pump is bad but am not too sure because if your loosing power uptop that means your computer is pulling timing from the current tune making the car go rich and run safer..so either iat temps are too high at WOT or something else is going on

only reason why am not too sure is because i dont really know if the car gives a code for a bad ic pump..

Well I put a new IC pump in about a year ago. The car was recently reflashed so im wondering if there is something going on with the tune. I saw something on here about if the MAF goes of 10khz that is its limit and at high rmps with stage 2 you will go over that 10k. Then once you go over the engine starts dumping fuel an adding timing......

I have problems with my bolt it started to jerk like the car wanted to die and sometimes does mostly when i turn corners also the rpms drop down to 0 like the gauge is jacked i took it to advance and put it on the computer and it thru up 2 codes for the cam shaft sensor could it be those any suggestions on what else it might be?
