Also perfectpower.com makes a piggyback for the 944, can a stock 944 ECU even be tuned for boost setting, like half throttle no boost situations and then boosted situations? Thanks

for the link Map stuff, check out
Guru Racing web site and go to the tech info section.
Basically, the link setup and the perfect power piggyback system are signal massagers (or signal generators) that modify the signal sent from an air metering device (afm, map, maf) to the DME. Since these systems allow you to alter this signal, you can replace a AFM and send a signal to match the original AFM signal.
Since you are altering the signal, you can modify the signal to instruct the dme to look at different fuel value in the look-up tables programmed onto the eprom. The limitations are you can only point to values found in the tables. If the tables don't have a large enough value (or small enough) you are stuck.
