Done tuned wonderfully to pegging at 4500rpms MAF only. She’s rowdy to that point and only has 10 def of timing

So, I bought a new Ford Lightning MAF. Set MAFIA to 4 (want to get to 15 lbs of boost eventually). Redid all part throttle tuning as original MAF was totally wonky. Did offsets like tuning guide said, was still off some so I offset a bit more. While stating WOT tuning 2500 to 4500 I noticed that the...

Here is the data log.

I don’t know why I didn’t do this before. Overlay of rpm, load, MAF counts, tps. Orange is MAF, dark red is load, yellow is rpm and light red is tps. MAF counts drop as load skyrockets, tps is constant. Is the MAF going bad? Wot At 6k rpm with no airflow would mean Extremely high load.....

Here is the data log showing RPM and load.

I have reviewed the tuning document. I got a pretty clean calibration without the MAFia and then installed the MAFia with the corrections as stated. The loads and trims were a bit off, so as per the tuning guide, I made another small correction and the trims and loads were very close to pre-MAFia. I...

I have a vortec supercharged 2001 Mustang GT. Mafia on setting 3 with Cobra MAF. Tuning with Advantage 3. Tuning has went ok until WOT tuning. When I’m WOT, the load instantly spikes from the steady 1.24 to 2.0 causing EXTREMELY rich conditions. How does the ecu calculate load at WOT? It is almost l...
