Im running a det block, ve head, t28 with headers and N1 intake, at 1.3 bar its holding boost to redline, which is 7600 i think atm, and im hitting the limiter all the time. Power band is quite wide, boost from 2500, so im prob just going to try and change earlier and save the wear and tear. Also running a 6 speed, so running out of ratios isnt a major problem.
