My mods are a NeedsWings DCAI and a Eurocharged 65mm puley. Car ran like a terror after these two mods. Then I got the tune and now my SC does not function. Euro. says it is not the tune. Jerry said they have but 3 tunes and have used each about 75 times. I am getting power to the SC line/wiring. Even dead cold it does not boost so that should rule out the IC pump. There are no codes. The K-40 soldering looks good. What else can I check before I need professional help. What does a EU reflash cost from the dealer? I hope that this can be resolved before I need to hope a reflash does get the sc working. Thanks all. Mark
