Which cam and head casting number?
Timestamp(s) on the log of where the bucking occurs?
Here man. Play around with this. You know to use VCM Scanner to clear LTFT's after each tune update?
I noticed what you were doing with the pedal lol. Main thing I was trying to address with the recent tune was the tip-out lean condition. If it improves great. If not then it is what it is. I'm...
Get a TMAP on there.

Run 2 looked great. Here's a little touchup. How are you feeling about the way your vehicle is performing?

Post your FIC 1000 data please.
Yes good point about using the GM-specific data not the 3bar generic data.
Good MAP option. IAT/MAP hybrid sensor.

Assuming you referenced the FIC data then you need to copy the 0kPa column of Offset to the rest of the the columns. Like you did for IFR. Values shouldn't change with manifold pressure due to the...
EGR isn't an option on Corvettes, so a stock tune won't be useful.
MAP linear/offset and IAT curve are in the Specs tab of the link. The wiring pigtail is in the Associated Parts tab. Make sure existing grounds for both IAT and MAP get wired in. Disable complex...
Get a new reg.
Asking a lot out of that 4L80E shifting at 6200rpm with an adaptive target of 0.250ms and no torque truncation.
Good writeup on how to do CL on a turbo setup:...
Don't even waste your time with idle stuff until VE is correct.
Idle timing is lower than commanded because the Overspeed spark adaptive is removing spark to maintain idle.
Why are you trying for 26*? Should be 18*.
About there now. I put some heat in it. Watch KR.
Wrong data.

You should be running a vacuum-referenced reg.
I recommend a TMAP so that...
Probably a good idea downsizing injectors to Gen IV GM.

Are you running a vacuum-referenced reg or non (corvette style)?
Do the data like I said and retune. It'll work.
The "ekt.hpt" file uses converted Ford data. It's more accurate than the AACorvette data. In that file you need to go to Fuel>Transient>Min Fuel Mg to 0.010 and set >Fuel Delta Min Incr to 0.
I've seen even the "good" aftermarket sensors from places like Jegs report wrong. I've also seen this lead to to incorrect cylinder airmass>incorrect (retarded) timing>incomplete burn fooling O2's...
The injector data is certainly not correct. Look at IFR. Here's the GTP data:

That's what I did in that tune. Set Min Pulse to repeatability based on SPA. Matched 2284 to that. Zeroed 2282. Set cam timing. Entered other data as presented in the excel file.
...and I...
