Whopps well the KE system our car uses, or whatever it is called.

Yes i have the 2/2/2 system all the way to the back. I removed the cat/resonators and the car sounds very nice and i do have gain in HP. A small striaghtway where i use to hi 90 ish now i hit 95mph plus..in the same straighway. I just want to get it tuned right .
Yes i do have the samller rad with engine oil cooler. I had in changed less then 7 months ago. I had the option of getting a US rad or keeping my Euro setup to cool my engine oil. Which i decided keeping the oil cool was more importent for my engine cooling- i have made certain mods to keep the temps under 95* C under hard driving.

I'm assuming i have some type of problem, my car feels weak to about 2k rpm, and it smells like unburn gas. I do not mind the unburn gas, since i'm young still :y but i have a feeling the car is not running at optimium a/f ratio and i think once i solve this..i could gain a few more hp plus not kill my engine.
