Over Boost problem
Just recently my 93 has started to make way too much boost.
If I stay in the gas while the turbos are under load, the boost will
swing all the away around to 20PSI if I let it (once was enough!).
I have the following mods:
Intake
DP
Greddy PE
MD Racing ECU.
I do not have a boost controller and have no other engine mods.
I've had the ECU for approx 3 years and it has always made perfect
12.5 MAX Boost.
Any ideas? Your help is greatly appreciated. I'm tired of having to
baby it for fear of blowing the engine....!
THANKS!

20psi 
I hope you only let that happen once.
If you made NO mods and it suddenly started boosting that high, the FIRST thing I would check would be the wastegate. You need to buy a pressure pump and test it.
