Ok, Chris has said that the j-bodies use Alpha-n (TPS,rmp)for their fuel delivery and not the MAP, however MAP is used for ignition. For a Turbo application the 2-BAR trick would seem nessesary to control the timing retard needed at higher boost levels.
Okay, now the curveball, I have a DIS-2 ignition that can retard based on RPM so based on this information would there be any real gains to using a 2-bar and re-scaling?
Thanks
