"My car has a Protomotive chip for the turbo, the only mod done to the DME."

That's the problem! Your DME ECM/engine is/are NOT stock.
Does the engine really have a turbo? Is so, another problem.
You're wasting time AND money by not focusing on all the mods.
Had a ECM sent in that had the same problem. Once the chip (junk)
was replaced, the engine ran fine. The turbo mods I've seen use
a MAP sensor too.

You also mention a CDI. Did you install an additional ignition system
with the stock ECM.

Bottom line: If really a turbo mod AND a CDI mod, get it back to stock!
