Hey All, I have a question regarding my series 1 r33 Gtst. At the moment It is running a factory ecu with stock injectors (both which I plan to upgrade within the month) The car is fitted with a HKS GTRS turbo and alot of other HKS gear. When it had a haltech ecu and HKS 740 cc injectors the car was pushing out about 270kw on a safe 13psi. However now that the ECU and injectors have been removed, the boost has been cutting at about 5000 - 6000 revs. Now my question is, I want to take my car out to the track next weekend and really give it a good drive. Would I be putting the engine at a big risk?? Sorry if this seems like a silly question, im a bit of an amateur but trying to learn! Thanks!
