    Easy install and works great!

    Posted by Chris Armstrong on Jan 4th 2020

    After much reviewing, I went with the ESS Engine and DCT tunes. They installed seamlessly and performed as I hoped delivering noticeable performance improvements including sharpening response of my 2011 OE base software without any trade-offs. Excellent customer service including 1 day flash file turn around on Christmas day. I highly recommend!
