I have a slp air box lin and a custom tune done by a friend with hp tunner. My car now bogs under full throttle basically headd 2 degress of timing in the low to midrange and raised the rev limiter. Feels like I'm running out of gas cause when I lift to 3/4 throttle the car speeds up. M6 car

maybe the added timing is now causing it to knock retard? put the stock timing table back in and try it, or try logging it and see if there is any KR.
