He called back 15 min later with a quote for $300 I made a comment that it sucked that it went out and he snapped. Called me a crybaby and demanded I come get my car off his property immediately. I offered to pay and he said no! Come get your car NOW! On my way to pick up car I called to let him know I was on my way. He stated I Better be there by 5 or he’s leaving. When I pulled up he was in his car, shop locked up and once we went in he charged 300 for the half tune and 9 dollars to use my card. He started in on me again. I just wanted to pay and get my car which was left outback in the alley. Horrible experience and shame on you Keith !!

  Bottom Line

  Thank you for your feedback.

I seen a lot of Mustang so I asked the tuner Chris Ortiz how good was he with tuning LS he told me to my face that he didn’t like tuning GTOS and LS . He sat down in my car for 2 mins charged me $250 dollars and said the O2 sensors where bad . So my car went back to the mechanic shop the mechanic shop said the O2 sensors are brand new it went back to the the shop with deferent O2 sensors the next day and he said the same issue. So I took the car to Black Market Racing the tuned the car and nothing was wrong with it. Also the Owner Keith Hellum was referred to another person on Facebook I told them my experience and I got message from the owner stating that he hate Mexicans and black peoples because I told another person my experience
