Crane Interceptor 1

Is everything else stock on the engine except the supercharger?. What grade(Octane) of gas do you run. What is your base timing set at? I can probably help you when these questions are answered. I have been programming the Interceptor II for 6 years and I think the Interceptor has the same functions just not the range of change for each selection.

Well a Interceptor is useless when using a FMU because it just floods the car with fuel under pressure and it is not stable. You really need 24-30lb injectors and the FMU can be trashed and the Interceptor and do its job. The Interceptor-1 does not have enough range to use it alone with 19lb injectors. The car will run better if you '0' the settings for the Interceptor and move your timing to 10-12 degrees at the crank and see how it runs. With 91octane and 5psi you can have 24-26 total degrees of timing.
