cheers for the info stu.

I expected that nearing tightening the limits up with a chip would require better fuel, but with the current price of petrol the extra performance wont outweigh the costs of swapping to SUL on my daily driver! (got the turbo to drive if i fancy going faster! lol)

if you have a christmas sale I think ill be very tempted with the FRST chip!!

don't know about everyone else but every time I hear something new or more detail about MSD i never cease to be impressed at the apparent quality and attention to detail.
