ok quick mods list
bigger turbo
looks like stg 1s
SAFC (not working)
MSD tach driver
MSD coil
upgrade fuel supply (blue)
return line
here a pic for better understanding
will post a pic of it in my car and maybe a vid if needed
ok so the engine fired up very quickly, but 5 sec into the run it starts to idle between 500-2500.
then if i try to give it any more than 15% throttle it will try to die out unless i let go.
does all of this have to do with the SAFC not working, is their any good
wireing diragrams for this??
suggestions??thnks

Out of the small mod listed above, I know of one that posses problems regularly. The MSD coil. Get yourself a stocker, and check your plugs. That is where I would start. From there it could also have something to do with the fuel modifications that you have, though I don't know much about those.
Thats all I have for you... sorry.
Good Luck.

yeah.. NGKs.
I heard the MSD coils don't hold up to the heat, which is why I pointed out them being problematic.

The rpm surge seems/acts like a vacuum leak/MAP problem.
That's about all I can think of/have enough knowledge/experience w/boost/SAFC. Just from experience with vacuum leaks.

The car would turn off and after three tries not run again till taken to a shop to clear the system or left to sit for several hours. So I do not believe this to be the problem
