I'm assuming you are running an A9P or A9L. If all else is good and your MAF curve is dialed in, all you need to do is lean out the WOT, you do that in the Base Open Loop Fuel Table. Set the top row to what you want your AFR to be. (If you're running that rich though, it sounds like your MAF Transfer function is not right)

If you don't have one yet, I'd suggest getting a wideband to monitor your AFR. I have the PLX M300 and it works like a charm. Also, EEC Analyzer by Clint Garrity is the greatest thing since sex and whipped cream for analyzing your datalogs.

 

i have an innovate lc1 wide band. i will try that thanks for the help do you go out on the weekend i would like to get together with you if you wouldnt mind to show me the ropes of the thing. i would greatly appreciate it

 

anyone else have tweecer please help

 

I go out from time to time but my car is down right now redoing the turbo and intake. That probably means my old tune won't be worth beans now. Would be glad to talk it ver with you. I'm in largo, I see you're in PC...which one, Port Charlotte, Pasco County, Ponca City, Oklahoma?

Oh, btw, set your fuel pressure back to 39 with the vaccum off.

Lots of good online reading and help at http://eectuning.org/forums
