Bigmac im skeptical on the car still making power at that rpm...any chance there was a bad pickup on the rpm lead to the computer from the dyno?

And auggie the back pressure get so bad at high rpm i cant see much over 6200 being beneficial...watch wastegate duty cycle skyrocket to maintain boost at redline

Sport shouldnt be different...there is basically a pedal multiplier when in sport..thats alot of the reason shifts are held longer and downshifts sooner because you are actually deeper into the pedal...i leave it in S when i race...i think the paddles are stupid
It's not just power though, its power plus gear multiplication. PP has a deep 1st and second so even might be making less power, its still making more due to gearing than if you shifted.

I don't have WGDC in my last log, I have turbo wastegate percentage (same?) and there was no spike at 6400+ about 66%.

Yeah i think its the same...yeah but fomo...when u do a steady single gear pull through the rpm you can see how it increases up top...want me to have a gander?...did you do a multi gear pull?

Yeah, I just looked at my last log for reference, a multi gear pull and I'm pretty sure you have it.

You need to do one of them Single gear pulls like ive been telling you lol!....4th gear is best but third would do...start at 2k and to redline

aj... Anything is possible, but if it had a problem the system didn't warn us and there were 4 sets of dynos... OEM DPs, PPE catted, PPE catted ceramic coated, and PPE noncatted .... Would have taken the same error 4 times at about 1-2 hr intervals for pipe changes.... here's the dynos.
Stock tune.

Yes, Dan took the limiter off in my tune over 2 years ago, but the dynos were with OEM tune before I ever tuned at all... Rarely go WOT, but put my foot in the right pedal every chance I get.
