Chris flew out to Phoenix to dial in the drive-ability of my Gen 2 viper with the GG Heads/Cam. The car runs absolutely great, excellent drive-ability for a car with a big cam. Chris is very meticulous and a perfectionist. He spent hours making sure every detail was just right. Couldn't have met a nicer person also. If anyone is looking for a highly skilled, knowledgeable and detail oriented Viper tuner, you should definitely give Chris a call. Thank you very much Chris.
