Turbo V8 5.7 HEMI Latest works 3 5 24.hpttest 3 lean spike at top of second gear and misfire code p0300.hpl
I was wondering if any HEMI Tuners could take a look at this log and see if they can tell me why i'm getting a lean spike. it appears to be causing a misfire code to happen at the same time too. when this issue occurs the desired Fa Ratio goes to stoich values for a moment. Thanks for your help!

Can you post a screenshot of the log? I can't view the newer log files

From just looking at the tune it could be Fuel Shutoff:
-Try disabling "Use FSO" in trans tq mgmt and esp tq mgmt. This cuts fuel during the shifts/esp.

Other unrelated suggestions:
-Part throttle timing map - lower the timing in the 105kpa row - part throttle boost at stoich with 10 degrees could be bad.

i tried to post a screenshot but the forum isnt working atm to add an image. it seems the fuel drops off before the shift happens and the fuel status momentarily switches to closed loop and the desired fa drops, even though its still WOT.

TM FSO. Torque Management Fuel Shut Off. This SHOULD fix it. Didn't make any other changes, didn't look for anything else.

BTW it's not just cutting the fuel it's closing the throttle blade. Flipped a couple switches for that. It might need more TM tuning instead of just flipping switches.

FIXED guys, thanks!!! your suggestions did help. it turned out to be misfiring due to a bad coil! replaced the coil and there is no longer any misfire! thanks
