I have a 2006 chevy trailblazer with the 4.2 I6. I have an eaton M112 supercharger and liquid to air intercooler setup. When I start the car, it starts fine, but flares up like crazy...probably 2500-3000 rpm. I'm guessing that since it is supercharged and there is a huge volume of air behind the throttle body(3" piping and liquid to air intercooler), it doesn't pull vacuum until it uses all this air and the bypass on the supercharger activates once it's pulling vacuum. How do I fix this?
There is not too many tables to mess with in the I6 file. I'm thinking I'll increase the values in the cranking ve table since it probably takes a second for the blower bypass to actually bypass.
Can anyone off some advice?
