I have an 03 6sp QC Sb. The mods are AFE intake, magnaflo 4", edge juice w/att, GDP fuel system and Dynomite 50hp injectors. With the box on 4 or 5, i keep getting a cel code p0193. From what i have read that is for high pressure in the fuel rail. I called and talked to edge and they said that i am not getting enough fuel and it is not a problem with the edge. I am thinking about just getting rid of the edge and buying the DiabloSport Predator PowerPuck combo and a set of guages. What do you guys think. I have checked all of the conections and still have the problem. thanks for the help

Have you put an aftermarket lift pump in yet?

the GDP he mentions is the Glacier kit...stand alone fuel system capable of lots of fuel pressure at idle.

Has anyone had problems with the edge juice making to much fuel pressure? Witch is a better product, the edge or the diablo. thanks

Don't know about the edge juice for model years 03-04 but I know for the 04.5-06 years it doesn't raise fuel rail pressure. Duration and timing only. So if it's the same then your edge is not causing your high rail pressures. Here's another thought, codes can be general meaning if it shows a rail pressure code doesn't always mean it's high pressure causing it. I know that low pressures can cause the same code to pop up. Is your GDP plumbed in properly? Are the filters plugged?

A variety of problems can cause a code. You have go through the process of elimination some times to figure out what's wrong.

On the 03 adn 04 the juice does raise rail pressure at lower rpms then it transitions to timing and duration only. I got this with my first juice and none since have given me this problem.
