got one I'm afraid to touch

I was tied up on an 08 SD with a 6.4 last week, replacing a high pressure pump and gasket. When I started it up, it had a check engine light. The customer had to have it for a trip to PA. He brought it back today. Handing me the keys, "Dont screw it up. I dont know what you did, but I got 26.8 mpg, with ungodly horsepower." The pipes are clean, with no soot. He figured the mileage with both, hand calculations, and lie o meter.

Umm...I would be afraid to mess with it too!

That does not sound bad for what the truck is.

did you reprogram it with the 08b07 flash?

 

[blacksnapon]

Its due for the flash, but I've never done it yet.

I'm figuring because of the po193 (frp too high), the pcm was trying to ramp down the fuel pressure and changed the injector timing. It has a circuit problem on the frp vpwr circuit telling the pcm it has 29,000 psi fuel pressure, when it should be around 5,000 at idle.
