So I'm getting major surging and power loss at just about anything over half throttle. The hotter it gets, the worse the symptoms (would make sense if car gets more fuel when cold). Driving "old lady style", you would never know there is an issue.

I've been troubleshooting with live scan data from the OBDII port.

No codes, ECT looks correct, TPS is smooth from 0 to 92%. O2's go from middle of the road to lean on WOT - but not pig rich like I would want to see.

So for the MAF. According to my app, idle g/s is around 5. WIth my foot on the floor *surging and missing all the way* to 5000 rpm, the peak g/s I see is 60. At normal driving throttle, I vary upto 30 g/s, so at WOT 60 can't be right. I know it seems low, but I didn't know if this was just something in the way the ECU reported it back to TorquePro (the app I use)...of if my MAF is gone and just not reporting a code.

Can anyone use TorquePro or another tool to get their MAF numbers and give me a rough idea of where I should be? If I don't want to go racing down the highway...lets say I just held it in gear (automatic) and floored it very briefly...like no more than 1 -2 seconds. Can we safely get a comparable number that way at converter stall speed?

 

The app also reports CFM, but is showing something like 1000 CFM at WOT...thats bigger than the holley I have on my mopar 360...thus, why I don't trust the numbers.

If someone wants to report the CFM from Torque, maybe it would still be useful for comparison purposes...but IDK...?
