Hello everyone,

I have a kind of silly question, but maybe someone here can either confirm or bust my suspicion i have.

So i had my SR20det Tuned by a known Tuner in my Area (Switzerland) and since that day the car just has a rough fell to it and the throttle response is as if its just flooding the combustion chamber, as if the tune is done only by the closed loop function.

I'd be happy for any opinions on that.

Best Regards

Do you notice black smoke when you accelerate?

Are you able to provide a data log?

no there is no black smoke while accalerateing. Base timing is also correct, ill probably hock up an mtxl to externaly log the AFR.

No the ECU got password protected so i cant acsess it.
