I have been reading the posts about the Magna Charger installs that everyone is doing. My question is if any of you are using the program that came with the Magna Charger or has the car been dyno tuned after the install? I am trying to guage if the results I have been reading are from just the kit as it is delivered or if the installer/tuner is doing something special with the setup. I am looking at the supercharger as a first modification since it is the big ticket item. And then modify the exhaust/heads/cam in support of it. Has anyone with exhaust or head modifications experinced a loss of boost pressure with the Magna Charger setup? In my experence with superchargers once long tube headers and high flow exhaust are added there would be a loss of boost pressure in the system. The same can be said of porting the heads etc.. usually a blower pully was used to set the boost pressure back up to support the higher flow through the system. Just looking for input while I map out the plan for the new car.
