Pulled a couple codes

**sevenmalards** · #1 (**permalink**) 08-21-2007, 01:24 PM

Truck didn't seem to be running quite right, when I go WOT it doesn't smoke as much as it used to. I checked for codes and I got two.

The first was:
P0748: Exhaust pressure control valve. high output

The second was:
p1211: injector control pressure above/below desired.

I have been running an edge evolution on xtreme, would that make a difference? I didn't pull these codes last time I checked for them, and I recently changed the injector control pressure sensor, or whatever it's called!

I believe the 1211 is the hpop not putting out enough pressure for the extreme setting.

What would be the possible solution OTHER than spending a truckload of $$$$ for a high performance hpop?

Really the only fix I think is to buy a custom chip or tuner or dual hpops to supply more oil. You still might get that code with a custom chip or tuner also, so I wouldnt worry about it too much.

So the edge evolution is poop?

I've REALLY been looking for a custom tune/tunes. Any suggestions? What is an SCT?

No I don't think the edge is bad, but custom tunes is where its at now. Here is a link to SCT's website. Its a tuner that can upload custom tunes from a programer like DJ by email and then download them to your truck.

WOW! I need to be more up to speed on technology! You mean I can pay for a custom tune, have it emailed to me, upload it from my computer and download it?
MAN, I NEED TO GET OUT OF THE CONCRETE BUSINESS!

I love my SCT...have basicly a stock 6.0...ran the 1/4 mi in 14.3 at 93+mph...all I did was a tuned SCT and separated the exhaust before the cat just for that day to attempt to keep the EGTs down since I was running at the track all day.
