Can anyone shed some light on the Red top,blue top and black top engine designations.
Presumably these are different states of tune but does this only apply to one brand of engine or one tuner or is it a code that applies to the same sort of tuning mods on any engine?
Is this a bit like stage 1,2 and 3 tuning?
