Face it...in the world of "tuner customers," there are some real prima donas. Eventually, every tuner will get a slam, no matter how good their customer service, in the tuner world. I owned a Venom 600 (not original owner of car), and had several questions for John. I always received quick, useful answers to my inquiries. I was impressed enough to send a few people his way, and they had no complaints.
But then, I avoid prima donas. I guess some people think that spending $40K on an engine means something...OK, well maybe it does...but be patient. At least the man turned over new turf in the Viper world, instead of being lost working on furrin cars (like Chevys).
