I know there is a HUGE thread on SC and I have already decided on the 3865.

Also, it says on the website that it wont affect factory warranty, but....have you guys experienced any problems with the stealership?

I only have about 9 months left on my warranty, so I could just wait if there is any problem.

Thanks.

 

yes. just flash it back to stock if you have to go back to the stealership.
They will use every excuse they can to try and make you pay for repairs.
