The upgrade is just over 10k km's on now and has always left a bit of a stain on the ass being a white gtr. It's going in for a touch up tune next Saturday. Guess we can have a look at what's happening then. Once it's had a puff though there's no real smoke again. Unless stop start traffic for a while and cruising then just that initial boost. Has all new gear. Z32's, turbos, injectors, pump, controller, etc. Thanks for input guys. Just a paranoid 32 owner I guess...
