Opp don't have that problem until abou 4k i boost at 10psi and then right when 4k kicks in bam. SUPER POWERS! If you race from 2500 rpm from a roll that not very smart if your trying to win. I haven't seen that lean spot though. But actually before I got tuned i did see that spot of 13s for no reason and then it hit 11s super fast. GOd i miss my car.
