I am just wondering why this takes place during the shift at gear change, I know that did not take place on our 07 Daytona using the predator. Out the exhaust it sound like a Big ol Fart during the shift.

?

2013 Challenger R/T 5.7 A5
Also when updating with Diablosport Intune DCX puts a back date on the pcm....On this car AE .. Back dating to AC. When I had the brakes checked today, they hooked up and said miles were 94,498..............while the dash says 58xx miles.
Now again today they updated the PCM . 2 times updated and I cannot load Intune again...........with out going back to pc and "Update" the intune.
This is getting interesting.

OK will do in the morning. What does ID change?
Thanks Mike.
On a log the throttle position percent does max out at 127.1. That i am use to. Now the throttle blade percent max out at 76.29. Should that actually be maxed out at 100?
It sure sounds as if the throttle body is closing at the shift point.

Mike here is my last written

Again why is there so much torque management left in the canned tunes. The predator had less where you feel mds on and off, All I can see is the "ECO" symbol comeing off and on.

Not bad for a stock car. Small hesitation at the shift but better.
Thanks

Had just finished making this tune for the new 5.7Ls on the dyno and street
Did it with 93octane. Not aggressive enough to worry about though. If you have 91 I can adjust it for you. Didn't even cross my mind at the time.
Anyway. The difference between the old hemis and the new 8 speeds is a lot more is hidden in the TCM with the shifting also they have them turned up quite a bit more than in the past on the engine side.

It grabs second gear real good in auto. Paddle shifting, I cant put my finger on it as to what it is in the shift. When it hits second its good. But some sort of "free spinning" during the shift the into second aggressive.
Thanks
I guess if I feed it BP it should wake up more.
