    Timing drop BBflash w/ FBO JB4 G5 v25 E70/91 oct + 50% meth

    On the bright side, the butt dyno def feels the difference in adding the BBflash. I now get a little rear end squirm during acceleration even WITH the powerflex rear subframe and diff bushings in there! Click here to enlarge

    However, on the logs after a couple runs, I see timing dive down and AFR leans. I'm new to tuning but I know that's bad. Click here to enlarge. I had meth add set at 60 and flow scaling at 70. Is that too high? I have overboost PSI set at 19.5 right now. Should I adjust that up/down? I'm not trying to get my stock turbos to last forever. Maybe at least 10K though I hope??

    I have a track day coming up so any advice, especially from Terry, is appreciated.

    Also, I'm still curious about what % of ethanol produces peak power. W/ the JB4 backend E85 flash, is 60% best, but if I get pro-tuned, then 100% is best???

    Log looks funky. Something is wrong. Without a CSV I can't offer any insight in to what, though.
