there is always more to the story. My pipes poped off at high boost. He could not make them stay! He changed just one of the cam gears so the settings are not lost. can not remember which one intake or exhaust. I am talking a GTS-t 2.5L.
Also there is more to the story. I put parts for over $8000.00 which includes:
Power FC, 550 SARD injectors, cam gears, new air flow meter (Z32), already had HKS Mainfold and large turbo with external waste gate. He asked me to change exhaust, I did. he blamed everything else but my car went from 165kw to close to 200KW. Now is tuned to 300kw at the wheels by UAS. Can show diagrams.
