Hi, I've ordered a K04-15 turbocharger for my A4 1.8T. Along with the turbo I will be adding a Scorpion exhaust. I'll also need a different chip so I was thinking of getting the TAP stage 3 chip which is designed for a modified K03 turbo and a scorpion exhaust. Would this be a problem? or do I need to have the chip tuned on a dyno? Regards, Ali
