Rough running

[Billy Mild]

I did some further testing today. I know the exact scenario that my issue is coming up.

If I run the engine in the 3000+ RPM range and decide to slow down with the car in gear, when it drops below 3000 RPM I start to hear some pops and burble from the exhaust. If I let the car get to the 2000 RPM range then give it a little gas or try to accelerate my car stumbles or hesitates. I got this on the datalog today. It doesn't always do this stumble, but it does more often than not.

This happened using both ECM's. So it might be a sensor OR the tune itself. I did notice that when the INT number is down around 60's when this stumble occurs. If I go WOT it clears right now. Its only for partial throttle.

Above is my OneDrive link to my folder with both datalog files. If anyone could review them it would be very helpful.

Is it worth looking into my tune as a possible cause?
