Well Im supercharged so I definetly need a chip. And not having egr is looking for detonation without one. I would say he provides the best workmanship but customer service is down. One of my buddies agrees with me on this one as well. He has a 2003 mustang gt with cams in it and nos which Chris said, "oh theres no need for a tune on a car with cams and nos". Im not bashing anyone here just quoting the facts. Yes crazy horse put my engine in my car, fuel system, brakes, trans, radiator, etc and only charged me 4800 which was a hudge job. The work is amazing but when a problem occured and he didn't like a part, he would call me up and bash the part and say there's no way he is installing that. I was advised by laracos on what parts to get too. Yes, I would go back to Crazy Horse for certain work but not all. Chris is weird, one time hes cool and the next total opposite.
