Had it finally done yesterday, top service from Mark @ AbbeyMotorsport!
A short movie with how it was done it's in the works
I'd like to take this opportunity to thank Mark for the great service and the zillion of things explained and questions answered, but also for the discount offered as promised!
For anyone still thinking about having it done or not, guys, don't hesitate, if you changed your exhaust, cats, plenum, pulleys, etc DO IT, it's well worth it! My car was running lean, but I'll let Mark to explain what we have achieved
