It seems my ride seems to be running a lagging abit, i'm not getting the response i'd expect and i am just wondering what you guys would looks at in terms of a performance service. Basically i've put in some spitfire to clean the injectors and also some stuff to clean valves and rockers etc as my they have been being noisey. This really has me stumped, im thinking new sparks plugs and ignition leads??? maybe have a look at the timing???
Could it be benificial to reset the ecu??

any help at all would be great :cry:
