if your ltft low is negative you want to decrease latency fyi, and if your ltft mid is negative you want a higher number in the scaling

once again thank you guys alot for your input. Hopefully i can get this stuff sorted out. I think i am getting a handle on understanding the trims and adjusting them.
I over complicate everything, and usually get these numbers mixed up when a bunch of info is coming in.
Thank you.

alright I just dont get WTF is going on it is still pig rich and have went through many many settings.
I am really wondering why it would run perfect up until I reset the ECU now it wont take any boost.
anything more than 40% throttle and 4psi and the car dumps fuel (9.0afr) and then has a fit like hitting a fuel cut which is as said before probably the spark blowing out.
any ideas anyone?

ya the maf is plugged in, I am going to start off fresh with a ROM and see if I can clear up the issues.

Resetting the trims wouldn't cause the open loop AFRs to change. Before you start doing WOT runs, get the trims as close to zero as possible. For this time of year, the only places dispensing 85% ethanol are west coast cities and a few select filling stations that keep the same mix year-round. My guess is that you'll have to have a higher scaling than what I use for E85.

Do some more stop and go driving to stabilize the trims. You'll have to iterate between tweaking latency and tweaking scaling. As someone said, LTFT Low is mainly dependent on latency. LTFT Mid depends more evenly on both.

Once you get the trims nailed down, then start checking the WOT AFRs.

Thank you for chiming in everyone, I will dedicate a full day and get nailing down the trims, I was a little confused but I understand the mechanics of the trims and such now.

Brandon, if you can't get them squared away this week, we can go do some logging and such on Thursday and try and get you on the ball.

Thanks Eddie I should be able to track them down have fun with the stocker again, it felt real strong!
