hey all i finally got my car up and running (ED XR6 TURBO) its only running standard comp and injectors big fuel pump and a obx rising rate reg and ive retarded the timing by about 5deg. just a question on getting it drivable with standard injectors and computer. ive got it running and driving but its surges big time as in vertually impossible to drive. how do ppl get away with leaving there standard computer?

Was is the rising rate regulator your using? 2-1 12-1???
Its possible that you have it hocked up backwards, if so that will cause the surging on and off boost.

Change ratio in" rising rate fuel reg" till you get mixure close.... Close plug gap down to .030 or .70 mm

the reg is a 12:1 and its not adjustable unless you buy the shim kits for them. i dont think i hooked it up backwards, but then again maybe cos there where no markings on the reg as to which line was in and out. i connected the line on the side of the reg as inlet and the line on the bottom as outlet.

I'm 99% sure you have the lines around the wrong way.
Malpassi regulators are configured the way you have it, but the OBX ones are the opposite.
Give it a shot with the lines around the other way, I'm sure it will come good, I've made the same mistake...

Cheers

Wont hurt the reg, but will most likely end up damaging your engine when it leans out to much

If you can T off the line pressure fuel line to check fuel pressure ... The fuel pump "MAY" not be up to the pressure put on it ??...Do you know exactly what boost you have ?? It could be cutting out due to map not reading boost above 8 or so Lb ??... If plug gaps ar too big you'll get park blow out...
