true
i feel like i am triggering reduced power mode, just dont now what criteria to look at at the 0mph or vs tps, and if it is driver demand related or maximum torque related.
going to try to capture it on a scan next few days fingers crossed.

It's not Max Torque or Driver Demand related, I have seen his tune.
One would almost just have to be there or drive the car or log the appropriate things to duplicate the symptom.

on C7's
who can dyno tune the car and get it right. It did this same symptom's. On the street it would fall on it's face when pressed for power then pick back up.
Right after I had the kit put on then. Straightened out on it own
after a week. Just got more and more better until I had it full rpm back then it never did it again. But esp since you have added long tubes and a meth kit you should get it to a known pro shop there are many.
Best of luck!

Like everyone else said, it's the tune. I will tell you there are certain settings on the c6 that are normally changed that when done on the c7 do this exact throttle killing stuff. Took me a bit of testing on my own c7 to figure out the exact settings. So, against the wife's wishes, I'm glad I bought my c7 to tinker lol.
Good luck.

despite the muggy conditions i was able to get a new best ET and 60' after disabling 'powerhop' and 'oil starve' under engine / tq management / general. disable at your own risk. I have a feeling it was just the powerhop one but whatever at this point, someone else can feel free to isolate further.
thanks goes to Higgs Boson for the pointers.
if the problem rears its head again on future track visit ill be sure to update.
