    I checked the Stage 1 Drive map and the lean spool is not checked. Guess I will give the 1.2 Scalar a shot and see what happens.

    All I need to do is change the scalar to 1.2 for each bank, correct?

    Went back to the OTS Stage 1 Drive map before trying out changes to the scalar. I drove it for like 2 mins before starting to do these pulls, so maybe things will get better/worse with time.

    It looks like that lean area in the 3-4k RPM range has disappeared. The trims look slightly better but what is becoming more apparent to me is the large difference in trims between the two banks. That does not seem like a normal thing when looking at logs from other people using OTS maps.

    I did a log at idle which confirms bank 1 and 2 have fairly different trims.

    So maybe this is strictly a bank 2 issue? Leak? Cat clogged? Something else I'm not thinking of..... Thoughts?

    Well let's go over all the things that can influence trims. At least you're asking in the right spot let's get you some answers.

    Here are the IPW values at idle. I have no basis for comparison so at this point the data is not particularly useful.

    Did some more work on the car this past weekend thanks to Dr. Euro
    - Stock downpipes were replaced with aftermarket ones without cats
    - All O2 sensors were placed, pre and post cats
    - Replace two vacuum lines from the vacuum canisters to the pumps (I think thats what they are) above the turbos.
    - Changed to a Stage 2 Drive map.

    It feels strong, no stuttering that I could discern.

    After a week of driving it like this the logs below were obtained. AFR looks rock solid to me Click here to enlarge
    The fuel trims are still different between the two banks, but maybe that is something I will just have to live with.
    Any last thoughts from anyone?

    Have had a hard time finding logs to compare to, but does this look like a normal ramp up for the HPFP?

    Some of the actual values are nearly 200 PSI below the requested in the section where the car gets a tad lean.
