True alex, but Im afraid Im loathed to chuck more money away now - Im afraid I have not been that impressed with any of the tuners Ive visited so far and Ive got no faith that it I go to another one they will be any better. I just want to back it off a bit and get it running OK again, not to bothered about loosing a bit of power, wasting a bit of fuel, reliabilty is more important.
