Will either the PPE or TTS extreme throw this code when running by themselves?

I'm not sure but I don't think that tuners are the culprit for the cause of the p1093 problem.There are many folks who have that problem running stock. I think it's a GM problem. I wonder if by adding the tunner that it some how raises the pressure in the rail and causing components to fail.

It is a problem with the tuners requesting more fuel than can be delivered. This is the very reason we have not released the higher power tunes for the LLY. We have been working hard on this problem and believe we have it solved for our race level tune. If testing continues well then we will move on to the Xterme level to see what we can do.

The PPE will throw it occassionally, but not very often, and only on Kill that I could tell.

Since it is thrown most often in 5th gear, and usually when lifting the throttle after passing, I believe it in the PCM's routine that checks the rail pressure.

If I had the tools to delete the code, I would. Big Blue runs like a freakin' clock, never codes when racing, only when on the street driving normal.

The LB7's burst when they starve for fuel, but seldom 1093. HEY!! The LLY's burst also! Funny thing is, they don't always 1093 when bursting. Heck, I've never seen bursting accompanied by the 1093 yet.

Is it fuel starvation? Not convinced. Driving data indicates otherwise.
