Hi have an 02 MCS
with a 15% pulley, problem I have is it feels really flat in general driving.
If you rev it at idle it's quite delayed just feels heavy sluggish.
But if you floor it from a standstill once it's got going feels ok,its a part throttle issue.
Also since fitting the pulley and 1 grade colder plugs it just doesant feel as smooth. Could I use standard plugs.
I have done the RESET on the battery and also the Speedo
Any ideas please
