Customer service is a joke, sadly. I'm not here to be mean but I feel it's my duty to inform future TT customers and current TT staff that better customer service is needed.
Brought my car in to have a tune made and three hours later it was done - seemed too quick honestly and also paid way more than I was quoted for too! Either way, I paid and got in my car and fought traffic back home. It wasn't until I got home a few hours later I started noticing issues. Yes, his tune fixed some things but made others worse - more so, WOT; had a couple stalls here and there (initial warm start); and warm starts always remained poor. Unfortunately, my car ran better before their tune; 'displayed wise' my car made good number though but from the seat of the pants to the dyno graph given something was off... But WOT was awful, so much it made me think about selling the car.
I was tuned 06/19 and mentioned my findings same day. I received repeated delays throughout communication even though Mr. Kaiser said he want's that sort of transpartent interaction from his customers - a reason I went this route. He sent me a configuration within a timely manner -thanks- 2 days later without instructions (even though I know how to log; done 100's of them). Received communication 06/29 saying he's reviewing it and on 7/10 staying he's sending out a revision same day or the day after, then I got ghosted! Next week, nothing. Following week nothing. Fast forwards a few weeks I gave up and got the vehicle retuned and it's back to it's original 'slap your face' glory!
Also went one step future (after I was retuned) and submitted a refund through my bank to look into the matter. After ALL this time, I received a message from Matt apologizing 'he dropped the ball' today, 7/31 after admiting Discover was asking for a refund on my behalf (only partial since I paid in cash for the rest). Needless to say, he apologized and sent me a revision -which I'll never use- and a message staying that "unforuntately, we have a signed credit card receipt for work which was done properly..." Yeah, okay... How is that a fair to say when I have to pay before you hand me my fob back?..
All in all, Matt isn't a bad guy just poor customer service skills. He'll act like your buddy so you spend $1,195 then ghost when you truly needed his expertise. Honestly, if you have a Mustang go with a tried and true Mustang tuner.
