guys have used SCT to tune their OBD-II computers while feeding them upwards of 12-14 psi of boost. They also swap out the MAP sensor for a 2-bar map to handle boost and vacuum readings



Pretend I'm dumb, what is "SCT" and what is a "2 bar map"?
I do understand the "OBD-II and the 12-14 psi boost very well though.

This Dakota chassis and drive train is in my 48 Plymouth coupe. More kick would be fun, but I don't want a V8. Gene
