Does anyone have experience with Dinan tuning. I understand that it doesn't effect your warranty. Looks like about $7000 to reprogram with new chip as well as new exhaust etc. How does this compare with going with a 550. I don't need to know that I may as well just put the 7000 towards the 550 I am more interested just in feedback from people who have do it on other models. What are the drawbacks? Also how soon after model launch would dinan have the upgrades available....Thanks
