So the truck is a built 6.2 truck with a Whipple and a cam. Truck starts with the stock tune in it. Once I add the 4 bar map sensor info it will not. The 4 bar was provided by Whipple in the kit. We swapped it with another 4 bar sensor and still the same thing. Truck fires and then dies. Doesn't stay lit for more then a few seconds. Any ideas?
