i have my car recalibrate/retune because rpm idle is too high, it makes car hard to stop (i had to press the brake hardly to make the car stop)

after recalibrate my car rpm is too low on idle position
and it makes car lack of torque and affect gear too late for shift up, there is some delay to shift up gear

will it go back to normal after i drive it for while? i have drive for 200km, and its still has the problem

No. 1-2

I read on another web/blog, After an ECU reflash or reset, the car just has to relearn how to idle. Is that true?



take it back to whoever recallibrated it, they messed up big time. There is nothing you can adjust yourself on a modern car
