FYI, all that car needs is a proper SharkTuning in the lower RPM ranges.

It would also be helpful to replace the Adjustable Fuel Pressure Regulator with a Stock S4 FPR to eliminate the possibility of user adjusting of the FP which is part of what is currently causing the lower RPM issues.

BUT, the main reason is that it has NOT been tuned below 4K rpms in it's curent configuration. Each time Ed upped the boost on the setup he would temporarily readjust the fuel pressure to compensate for safer fueling on the top end until I could come down and retune it for him with the SharkTuner, but we only tuned the upper RPMs and WOT per his request.

This was done on 2 occasions as boost was increased from approx 6 to 9 psi or so. On both of those occasions Ed wanted me to tune for 4k and above ONLY as that was all he cared about for the way he drove and used the car.

It was funny, I asked multiple times during multi-hour long on road tuning sessions if he wanted to tune below 4K and and that I could make it get better fuel mileage, drivability, etc, etc....he would just laugh and say he never drove it like that and wanted to concentrate on the upper powerband only for the upcoming race etc.

I would still have tuned in those area anyway, but sure as heck we would drive for an hour or more and he really never would be below 4K for me to even try to adjust those areas.

One thing I remember distinctively is that even after an hour plus of truly driving that beasty in "full anger" non stop continuously from 4k to redline over and over....the temp gauge never moved pass halfway on the gauge and the ST log files also confirmed how cool it ran...pretty amazing!

Nice ride you picked up...I would highly recommend getting together with someone with a SharkTuner 1 with the EZF option and do a complete tuning on it as it has never been done in it's current configuration. If you do that you will forget about messing with any other Engine Management system..AND you can continue to enjoy the car as it was intended, ie. driving it.

I fear if you start down the road of putting on an aftermarket system, my crystal ball tells me you are gonna have much less seat time in a fanatastic 928 for quite a while as you try to get it all sorted out.

Best of luck and let me know if I can help you with anything you need on it.

The biggest thing that needs to be conveyed from my end is that I inherited a lot of issues that came with this car. I did not cause the issues and I did not abuse and blow up this car.

It never ran properly from the start.

How would you feel if you bought the most beautiful 928 in your mind only to find that you cant even drive it without stalling issues and popping the hood everyday to wipe up oil from your beautiful engine bay. It is not what I was hoping for or expected.

DR and I have a plan and he is the man. This car will become a RELIABLE 928 again. One you can open the door and go for a drive and have fun and not worry about anything. I look forward to that day because I haven't experienced that yet!

I am not pointing fingers, it is what it is. At the end of the day I feel I will have two more friends in my life, ED and DR. That is more important to me than saying this or that or all that crap. It is what it is.

I will leave with this someone sent me a pm in regards to me blowing up the car and begging for free parts and money! I thought that was funny. I think they maybe to much when they type.
