For those few of you running the MP stage 1 tune on 91 octane, how many of you experience a surge/boost spike from 3-4k rpm during WOT in 1-2 gears? Sometimes if I am heavy on the throttle in Sport/Sport+ I feel like boost comes on not so smoothly, and a few seconds delay before going back to boost. Could a catless dp fix my issue, or is 91 gas really not that suitable for the tune? My car only has 34k miles with 5k oil change intervals so I doubt there is anything wrong with the car.
