I have been having an ongoing issue with my car not coming back to normal under deceleration. Running an edelbrock supercharger at 9lbs boost on a forged 5.7 with big valve heads and high lift cam. After going into wot for a few seconds and then getting off the pedal the car will stay at that rpm and basically cruise like that for about 15 seconds or more with no pedal input. The afr under wot are around 11.5 and after getting off throttle the afr will peg at 10.0 and stay that way for a bit before slowly returning to normal 14.7 afr.
Car was tuned by Hemituner AJ through a speed shop on a diablosport unit. Have recently swapped over to the hpt unit. Can someone take a look at the log and tune file and see if something jumps out as being out of line.
