Gents, Thought Id do a few logs this morning to see what sort of timming pull Im getting, fairly happy with it really, seeing 1s and 1.5s mainly, one 4 on cyl 4 in about 6-7 pulls to redline, but otherwise OK. ambient temp this morning was just 1 degree. However, I did have a MAF signal too high intermittent fault code before I did the logs, so I cleared this code, then did the logs, and the code was back. Its an AUM engine with a stage 1 map, jetex filter from bill, and a 3 DP/decat. Peak airflow this morning was 182-183g/s on most of the runs, suggesting around 228bhp. Any thoughts? Ive heard of MAF too low, but never heard signal too high before!
