Everything basic thing you need to know is is these threads.
Wiring up an AFC is not hard, you can do it yourself. Read the manuals that came with it, make sure you have it set to Karman sensor, arrow up, four cylinder, and your sensor check is good. 0% across is stock settings. Ya I know this for Eclipses, but the principals are the same. Get a data logger before you make any adjustments.

 

i had it prof. done and they ripped me off. I lost 40 miles to a tank and my rev dosnt match with rev on the tach i dynoed in at 245

 

The rev mismatch is a problem, I had that problem too. Apparently it's no big deal and it does not matter but I still did not like it. Losing 40 miles per tank is very probable from running richer. You are also probably belching black smoke....
245 whp is not bad at all on a DD dyno..... What dyno did you use?

 

Dynojet. My revs off pretty bad never really goes above 3k i checked it all couple mins ago and everything seems to look good using the directions off evomoto or something i have my rev wire into number 88 on the ecu dia. is correct? It is the camshft position sesor signal? And how do i get my gas mileage back to normal without a expesnive dyno?
