I have a modded GTR r32 running an apexi power fc. Ive been to Advan Performance-no luck, MRT,and a few other places to get my car tuned. I either get really laggy bottom and mid and good up top (Advan) or doughy semi solid mid range and no top end .
I have almost given up trying to tune this car over the past year. Its got 700cc injectors,apexi fc, highflowed N1 turbos and heaps of other stuff but no one seems to be able to tune it right for good top end and good mid range.
Please let me know if theres a workshop you could recommend that G'tees their work.
Much appreciated!!
