Yes meant Motorsport Developments. The car actually does beautifully from 1psi-18 or 20psi, the air fuel ratios are pretty safe, pulls like a freight train. It's in upper revs (5,500+) where the rev counter starts freaking out and the air fuel goes more lean, if I go full throttle under those revs, the turbo spools quickly and boosts easily/smoothly with no lean fuel
