Got My Car Dynoed Today

if the stock ecu see's too much detonation (not sure how much it considers too much) it will retard timing to protect itself

yes it will. but that isn't rich and retard. that is just the knock sensors doing their job.

I had a cat back exhaust on my car it used to hit r and r on even stock boost winding up boost to 10psi would make the problem worse. Gap the plugs to 0.8 and get yourself a SAFC or Power FC fixed the problem for me but on hot days the car would ping at times.

Before uping the boost its a good idea to get yourself a front/dump pipe, highflow cat and an upgraded less restrictive intercooler the R34 GTT would be perfect.

With these mods the turbo will not have to work as hard to produce the required boost and the air will be cooler which means less chance of detination. With these mods you will have around 180-200rwkw depending on the condition of your engine.

This is what worked for me.

cheers

I agree. This is rich and retard. Checkout my full story on this thread.

Sorry for the late reply fellas, had no internet connection for a week. My problem is mostly gone. I got the plugs regapped and the problem seems to have disappeared. I was told that the the irridium plugs are very fidgity and that the NGK coppers are just as good. Boost now holds steady at 10 psi. However on full throttle my car seems to have a huge flat spot up until 6000rpm where all of a sudden it has more urge. Its a more rush of power out of nowhere. Can anyone explain to me what is causing this?

Thank you to all replies

I think this is a common problem, usually fixed with a SAFC or ApexiFC.
