Just want to piggyback and say that my 15 CTS 2.0T gives engine 'rumbling'/shaking (hopefully not knocking? I don't know) under heavy acceleration using this tune. Car drives smooth until you get on it, especially when coming from 2nd/3rd gear, it just trembles. Very concerning. It has been present ...

Stellar! Thanks for the FAST response! You have a new customer

Just want to verify that the '15 CTS 2.0t is included? I see on this page that it says 2013-2015 CTS, but I don't see that in your post here. I found your tuner from your post on the Cadillac forums but figured I would double check. Thanks
