    That is ~12.24 AFR if you are using 14.08 as stoich. A little lean for my taste on these cars. They tend to like a little more fuel.

    I have my MAF transfer tuned to my Airaid CAI. I haven't had any WOT issues and my correction bounces around the .99/1.01. I've resorted to using Livewire II until HPT releases the detailed scanner. The 2.24 Scanner doesn't give me enough of what i want to see.[/QUOTE]

    You do realized the correction will bounce around that correction regardless, it's the commanded lambda. Unless your fuel trims are dialed in.

    None, timing isn't very high.

    Yup. Fuel trims are about +4%. I think I'm getting a good hang on things with the little time I've spent actually changing things vs just reviewing how the car runs in logs. Haven't changed much but she pulls strong, idles with the cam lope and the throttle is just how I like it.

    Still Learning a lot. I appreciate all the help here.

    Yea 4% ain't bad. This car was locking in at -14% for the ltft's and still triming up to 5% on the stfts in wot, before tuning

    That definitely is a bit out of bounds. I am guessing you dialed in the MAF transfer function to rectify?

    Yep, was a little cumbersome not being able to use a histogram but I made it work
