Its always been an issue but it has been getting more noticeable now at normal driving and hard pulls and reverse. It feels like its pulling timing or a cut in fuel all through out the rpms range and in idle and low speeds. I have good fuel pressure at 62psi even when the stutters are felt. I logged it while reversing and on drive with my foot on the break, since i was in my garage, but it does the same thing while driving normal. The spark dips down to around 11 when ever it stutters. I still havent heard back from my tuner. Is there anything to check? Im attaching my log and tune file, i need some pointers thanks, added a video as well https://streamable.com/r39ai8
