I dealt with Mitch and his tunes were great didn’t hurt that he was 15km down the road either. I eventually switched to ppei because my buddy’s lml had his tuning and it was a monster...... till the tranny went. I wouldn’t hesitate with either one. I threw korys tunes in my truck before leaving on a work trip didn’t end up getting into rocky till 9:30pm with an empty diesel tank. Truck wouldn’t start I was a little angry thought it might be the tuning kory answered the phone gave me some suggestions turns out I had a weak battery and because I had no lift pump at the time had the 1/4 issue. Me being an idiot. Kory didn’t a follow up the following day after batteries and a full tank was thrown in it and it runs flawless. Was super happy with that customer service
