Been having an issue lately and dont know if its tune related or an electrical gremlin. Usually happens with steady light throttle input. The car hesitates for a split second as im cruising along. So far it hasn't happened at WOT. If my picture loads it will be marked with white arrows.

ok your issue may be a few things, the RPM signal into the ecu [from the pip] shows 15000 rpm for a split second this is your hiccup. I do not see the other sensors freaking out so we can rule out an issue at the ecu.

Well i got another datalog, but the car didnt act up this time. It usually does at least once or twice while im driving. The above datalog doesnt show it, but i think it actually did it 3 times total.
