    Your cranking VE doesnt match your VE table cells. I prefer to let my RPM dictate PE enable, not min torque settings. Transient fuel to wall impact should be increased some due to larger injectors spraying more fuel. Evaporation rate would more than likely decrease some since more fuel will be puddling up on the low end. I dont like knock sensors being disabled.

    Honestly, not a bad tune If the vehicle is running well and youre happy with it. If fueling is staying steady when youre letting off throttle or at tip in then i wouldnt worry about the transients. I would use the data in the VE table to make the corresponding cells match in cranking VE. Then use interpolate to fill in the empty cells of the table. Knock sensors and PE are just a personal preference, they should be fine if youre happy with the settings.

    It runs ok.. I mean it drives like stock pretty much .. it needs gears because I'm running 32.5" tire with 3.73 so top of 2nd gear is 100mph .. if I could get a little more power below 4k rpm somehow that would be great but I think timing is about as high as it should be �� thank you sir for taking the time to look it over and I will make your suggested changes .. I also have a 340lph pump going in the tank soon along with a fuel rail pressure sensor I'm gonna repin to the fuel tank pressure ecu pinout .. gotta pull trans to do torque converter because of burnt lockup so was planning to swap to 4.56s at that time .. that should wake it up on the launch eh ..

    only thing is brief lean tip in and out and then closed loop fuel trim pulls fueling away from where I had it open loop tuned with wideband through Egr pinout

    ok I increased impact by 5% and decreased evap by 10% see how that does ..im also running a 160* thermostat and cooling efans keep me between 180 - 200 no matter what ambient is .. see if that does anything noticeable

    If anyone has any MPG tricks that would be very helpful as well lol I mean I'm getting the same as stock on the hwy pretty much but another 2-3 mpg would be ideal anyone with a similar setup willing to post their tunes? I'd like to compare notes if you will eh.. thanks

    The only way your VE table makes sense is if the fuel pump can't keep up. MAF looks overcompensated, too.
