Hi Mate,
I have recently installed a FP red turbo and the car is not hitting 25PSI until 5K RPM; I have tested for boost leaks and wastegate is on full preload but no difference. Car is a stock Evo 6. Can you pls share your thoughts on how did you improve your spool? If possible can you share the ROM you had used. I am on 91 Oct.
Thanks
