I have recently done a fairly major build with my R33 GTR including Trust T517z turbos, 700cc injectors, pump, reg, Intercooler, z32 afms, pods, etc.
During the build I had a power Fc installed, although no one locally (North Queensland) can tune the thing properly! I have tried two places in Cairns and one in Townsville with little success. The car is running ruch, has a flat spot at 1700rpm and is not performing to potential. The package above should yeild 300 - 340 4wkw at 20 - 22 psi, which should be impressive compared to the 175 4wkw R33 GTRs run standard. I do not feel an improvement of this magnatude at all. I am confident that mechanically everything is fine - many compression tests, flow tests, etc have been done.
I could truck it/ drive it to Brisbane, Buy a DataLogit unit from NZ (Do they even help?) or get a tuner from a reputable garage to send me tuning info - Im not sure which way to go.
Im frustrated and at this time any advice would be muchly appreciated.
Thanks.
