Hello all.... i recently had my stock 2017 camaro SS A8 tuned i just want to have a couple of questions answered. Every time it shifts it kind of lunges is this normal after the tcm tune? Also when at wot the shifts are very snappy is this normal as well? im new to this tunning stuff and just want to get a better understanding. I'll post my tune incase someone wants look at it.
thank you
Depending on the tune, yes the lunging feel is normal. It's from the pressure increase on shift and the reduction in torque management control.

I don't have a stock file handy to compare too but it looks like someone upped the pressure and disabled upshift TM but left the desired shift time long.. This will make a slip bang or slip lunge like shift.
This isn't the right way to tune these. I'd put the pressure and TM back.. Then shoot for a reasable desired shift time. .22-.25s is a quick up shift for example. There are spots were your tune is asking for around half a second to shift.

Thank you for your response... I'm new to this but I'll try and put the pressure and the TM back and change the shift timing
Thank you
did you have any issues with the tune? thinking of tuning my stock camaro 17 SS transmission tune for better shifts do you recommend and changes before a trans tune?
