I think arquing is totally pointless in this case with the accuracy about kta-racing rr.
But i say about that rr result that i have dynoed 5 cars there before, there has also been many powerful factory cars and graphs has always been what there should be. For example bmw m5 e60 gave what it should. I dynoed my ex rst there and result was 194bhp but now i have pretty good head and i think that turbo is most important thing. I really dont remember what map i did send you but i can take a look about that spark map what i currently have in my car laptop & ecu.
Is that so hard to believe that my spec is working so fine? I was first pretty surprised with result because it gave 259bhp in first run without any cam timing or ignition tuning. It was 100% mapped in normal road. The rest of the power was found when i adjusted little bit more boost.
But if you still hesitate that spec and power i can next summer go to different rollers and take run there. There is still no any sign that any place is tearing part and i bet that performance tells something. I will take quarter mile run to prove it next summer. I still know what 194bhp rst feels, and that my current setup is something else.
Also fact is that i dont burn rubber and do traffic light race. I think one key that your engine and gearbox will live is that driving like a normal car most of the time spares engine and gearbox.

edit:

And.. i newer broke gearbox with that 194bhp power and that car was usually driven like i am stoling it. Those mad years when i was young.
