Car is modified but with stock DD tables. From a stop, I have to be careful from a stop in particular. I'd like to dial back tip in sensitivity . File attached for review.
Thanks

Do you have a throttle controller on the car?

I often have to reduce the driver demand tables for off idle throttle snapping after the majority of tuning, but that's because of timing changes and everything that normally peps them up. Your driver demand looks greatly increased off idle, but I didn't compare it to a factory tune to know for sure. Just going by appearances. Then as Jason pointed out your torque model is dipping a lot then hits the sudden torque increase off idle. Probably makes it worse.
I compared DD tables to my stock file. I didn't see any changes in off idle settings while the bottom three lines were increased over stock. I am lost when it comes to torque modeling..Quote:

Your DD is OEM sans the 98% and 100% lines for a 2015 Z06. Strangely jacked way up there but not sure why its so high. It's not hurting anything, just strange logic.
What I meant by that was I often have to lower the stock DD tables after perking things up.Quote:

I don't change tq tables or DD tables typically unless a vehicle went from stock to a wildly totally different setup.
Car has added a Maggy 2300, flex fuel. 103 NWTB, 5" Intake and JMS BAP.
