True. It's just that my mapper is away this week, (typical on my week off work) and was just looking for a bit of insight.

It could be anything ranging from spark plugs,fueling ,timing.etc etc.the fact you are running a simtek ecu is why I recommend you let your mapper plug in and give you the right info first time.SJ.
