JB Stage 1 N55 X5
Hey there. Had the JB on for about 10 days and the extra power (up to 50hp claims) is just not there. Feels a bit sluggish on bottom end. Boosting about 10 lbs. Had many turbos before and you should definitely feel 50 whp difference. Ran a few times with a friend with a '13 335i and pulled away every time. Any experiences out there?
