Engine lumpy until 3000rpm and then pulls cleanly but slowly to 7000rpm
(It has only done 5000miles)
In an effort to release more ooomph, I have looked at the following:-
Removing existing two air filters and resonator valve to improve flow into the airbox.
The major improvement from the 190 upgrade kit appears to be the ECU
Can I simply plug in an 190 ecu to guage any improvement or should I just get the existing one remapped on the rolling road at Falkland?
