Right im gettin some hold back/judder in low revs if i slam my foot down and keep it down i get a LOUD bang from the zorst! Sounds cool but im guessing im over fuelling it?? my mpg is pretty s**t too! Plus the AFR goes over to 16/17 red for a split second it then clears and hammers it
If this is the problem whats the way to solve it??
Cheers.
