For sometime I pondered the merits of getting the white mamba supercharged by DLM. I took the plunge and got my car back over the weekend. I have to say I made the right decision. Doug's shop is filled to capacity but his "winning customers" philosphy made me feel comfortable. The 20 miles ride back to the house was an awesome experience. I recommend the upgrade to anyone. I put red supercharged lettering below the rear bumper viper sign. I also placed them on each side of the sills just to remind the high performance people that Vipers can be energized beyound their original capability.
