Hi my name is Karl i have a Skyline R33 Gtst series2 and i am having trouble finding any good dyno tune places. I recently just blew my engine up and have just replaced it with a low km engine and have just had it dyno tuned which cost me $440 and it is running like crap. Worst than when i took to them and i took it back and they said they have done there job. When boost kicks in it starts to miss and carry on. Anyone have any options or know who i can go to to correct the problem.
