Well, the 03's have a return style fuel system with a regulator that is vac / boost referenced which allows higher FP as the boost increases. I took the rubber hose that connects the FPR to a boost referenced source and replaced it with a hard plastic piece of tubing. Not sure if that gave me a better reference or not but in theory it did. The rubber hose was too flexible IMO for the FPR. The hard plastic is very unforgiving.
The 04+ non-return systems are different and do not see this boost / FP relationship. The 03 system is better IMHO for this reason.
