Last year I got tired of fooling with my Holley and switched to a TWM injection system and FAST XFI. All the work was done by a shop in Chantilly, VA called EB3. If you call C&C and say "fuel injection" the response is EB3. Superformance recently sent a few cars their way that they were having trouble tuning, and EB3 took care of the problems. Definately worth checking out.
