Yea, ive seen those chips that tell the computer to run rich on gas, but can you make that adjustment without using that chip?. And, if possible without accessing the CPU.

Your kidding, right?

first u dont wanna run richer unless ur gettin more air in the engine where u find urself running lean.. almost every car from the manufacturer already come runnin rich to be on the safe side of things which is already sacrificing some power.. to anyway to get more or less fuel in the engine with out touchin the ECU u can use a adjustable fuel pressure regulator

its a resistor that you can buy, that tells the cpu the air coming in is colder, and adds more fuel / opens the throttle. How was i so off on asking that? geeez.. some tighties up in here heh.

Ebay right? I'd stay away from these "revolutionary" ebay items. Most of them are pure junk. Unfortunately to get a significant horsepower increase you need to spend some $$$$

im running lean and I dont know why... i think i was up to the 15 ratio. At wot i was like at 14.2 .. go figure? i tought we were supposed to be around the 12 ratio at wot?

12.6 a/f ratio usually is best power and on the safe side to for if ur boosted some testin guys have done on the KL engines found that a 13.8 a/f ratio is best for makin power all motor
