Help please I have an 2002 MCS
which I have fitted a 17% pulley and colder plugs, carried out ECU reset via odo button
Car initially ran better more boost but much improved pickup at light throttle openings.
After a week it just feels flat obviously it goes at full throttle it feels almost like it doesant like the colder plugs, any ideas anyone
Also what suggestions for what I can do for better pickup my Sonja's an 06 MCS
with the Works Engine and they only run a 11% pulley but it feels much stronger at low revs.
