Jenkins is the man. He admittedly has not been very responsive in the past but he has his new business up and running now and has seen the light. I have several cars and have used several tuners, and I can honestly say that DJ is the most experienced, top notch tuner that I have ever used. He has done everything to my car from oil changes to supercharger installation. If you have had a hard time getting in touch with him in the past, give him a call, you will be surprised. He is the best out there. If anybody has any questions, feel free to email me.
