Datalog opinions


Recommended Posts

Been having some rough spots between 2400-2800 (spots of hesitation). Not sure if it is the typical stutter or not, but they are very noticeable any annoying.

Did the typical datalogs today. Anyone have any advice?

Running on custom TA tune.


Hesitation was there before the SPT intake and custom tune, but it only happens during normal driving conditions when just slowly accelerating up to speed. The slow acceleration log I posted didn't catch it, but I will try to capture it later on today.
