Thanks in advance for the help. Have a friend here in Davenport, IA with an '05, cam, headers/exhaust, cold air intake. Runs like a raped ape on the highway and open throttle - but struggles down low and in stop and go traffic. He's looking for a place that can properly tune and willing to drive to get the job done right. Thanks again.
You might try Hartek in Iowa City. Their tech is really good and a factory trained Viper tech (I think). A few us us from the area have our Vipers taken care of there.
