Just wanted to add my .02 cents to this as well - I've had the experience of two master tuners for EcuTek - of those experiences Toni has been a great guy to work with - and very responsive, usually within 24 hours at the latest I'll have an update to logs. My car has actually had over 10 revisions, each one a little bit better than the last (car is being remotely tuned for Flex Fuel, probably much easier to do this in person with the tuner, but hell I live in Ohio..... enough said
) - the few times I had questions around CELs I had a response within 2 hours.
Toni's service is awesome, even when I can guess his enrollment numbers have gone up thanks to what happened recently with the car fire - I do recommend him when asked by others that were in my situation.
