MPS Gen 2 Stuttering 1st Gear 4500rpm and up
Hi Guys,
Can't seem to find this fault happens on first gear if its stretched out past 4500rpm, and no other gear, I did a data log, it looks like at 4500rpm the AFR drops to 8.* and I dont know why, it does not happen on any other gear.
Please check my logs and let me know what you think the fix may be.
Log 1,2, is only first gear
Log 4 is stretching out 1st,2nd and most 3rd. Hope you can help.
I have HPFP, CAI running stage 2 tune OTS I did a MAF call just recently, but this was occurring before hand.
Let me know what you think.
Also a few questions:
What should the Vacuum sit on idle (mine sits around 9.5/10)
