I have a CIA 75 mm tb and plenum with no cats or resinators....My car is running way to rich. I have a Diablo tuner and I am needing help deciding ho much to lean and how much to rich. I can adjust from 2k-4k and 4k-6k (rpm) someone help me out! thanks!

RE: air fuel ratio

You will need a wideband to adjust it correctly.

RE: air fuel ratio

No dont touch those. You need a professional tochange those for you with a dyno tune.

Your air fuel shouldnt be off unless you changed you MAF meter, or something else I cant think of.
