this is very weird and I have no idea what could be causing it. it doesn't happen 24/7 but it does occur at least once a day. whenever I am in any gear and I'm accelerating normal and I get off the throttle the RPMs kind of spaz out , fluctuating within 300-400RPMS of whatever RPM it was on when I leave the throttle. the car also kind of jumps back and forth. as if it has some sort of inconsistent gas flow. this only happens for a good 10-15 min and then stops. if anyone can help me out here I'd appreciate it

Your tune is the most likely culprit. Have you attempted to contact the vendor?

that's exactly what I thought, just haven't gotten around to doing it because I wasn't too sure if it was it. I'll give them a call soon
