A&C Performance tuned my Viper with 712 rwhp (Dyno pics)
Just wanted to share my experience at A&C Performance in Murrieta, CA.
I had my Paxton installed by a local guy who lives close to where I live, but he is not a tuner. After getting the Paxton installed, I drove it for a couple of months or so before I decided to take it for tuning as I knew (from the butt dyno) that I am not getting what the car should be capable of after the supercharger was put in.
So I learnt from the forum about A&C Performance and called the shop. I talked to Todd who was very patient and went over everything related to tuning and patiently explained the whole process in detail. I felt very comfortable with our discussion and sent the car over to him on a flat-bed (had to go out of country on a business trip and decided to use this time to get the car tuned). Upon my return at the LAX airport, I called Todd and he readily agreed to send someone (Mike) to the shop at 9 PM at night to give me my car so that I could drive it home to San Diego.
The car made 660 HP at the wheels. Mike printed all the dyno sheets for me and answered all my questions with great detail. He stayed at the shop with me for at least half an hour without trying to rush despite it was pretty late.
The next step for me was to replace the exhaust. I had my local shop do the install and decided to get the car re-tuned and dyno'ed again with a new exhaust and removal of the cross pipes.
I called Todd and went over to the shop the next day. We did multiple pulls with Todd tuning and re-tuning and fine-tuning various parameters. Todd was very thorough and didn't try to cut any corners. He kept making changes until he was completely satisfied with the results and at that point the car made 712 rwhp and ~634 ft-lbs of torque! There is no other mod in the car. Just the stock Paxton and the Exhaust. These numbers are SAE Corrected. This tuning is still with relatively safe timing. Todd thought that it could hit 720 but I didn't want to push / risk it, so I decided to call it a day.
The car drives like a charm. The Vipers should come out of factory like that!
During this whole exercise Todd & Mike also identified a problem where the belt removal tool was left on the pulley from the original install which should have been removed after the initial install (the install was done by my local shop - Not A&C Performance). It was causing loss of boost which immediately went up as soon as the tool was removed.
It was great working with Todd. He is a really cool guy, really easy going and laid back...and most of all a GREAT TUNER!!!
I would HIGHLY RECOMMEND A&C Performance for all your Viper needs!!!
