Not sounding the same

[RossTi30N]

has anybody who has their car tuned ever had it when the exhaust note just don't seem the same (quieter) and the pops and bangs don't seem to be the same and also feels more flat when trying to accelerate like its not got the power it had before?

I recently filled up with fuel and since then its not felt the same.

Could be bad fuel? I know you’ll probably run 99 ron as it would have been tuned with this, but even then, it’s not that uncommon to have a bad tank of fuel occassionaly.

That's what I'm hoping. Once i use this tank of fuel and fill it back up hopefully all will be good again.
i wont know until then though. If not i really don't know what could be causing this.

Make sure that no one has shoved a potato in the tailpipe. More likely to be water in the fuel from bad petrol station forecourt tanks
