It's quite logical that it starts and idles OK on the greens and Bayjoo chip because at idle the turbo doesn't do anything yet. But I guess the higher the revs get the bigger the problems will be. You should really get a different chip in it. But I wouldn't think an off the shelf chip can be done on a GT30R and you would need live mapping. If I were you I'd contact Motorsport Developments (MSD) again as I assume that's what you mean with MD.
