Can you provide some more details?

What does your fuel system consist of? How much boost are you running? What type of turbo? What exactly have you done to the engine internals?

I'll highly suggest you to get a stand alone system. A lot of ppls here will tell you tuning is everything, which is very true...A stock ecu just wont cut it, at least not for long ...a true stand alone will allow you to tune the fuel and timing a lot more accurate through out the whole rpm band. Its been more than a year now since I installed the DFI, I do a lot of autoxing and some road racing with my turbo and the motor still holding up strong.

properly tuned engine management computer, or just lower your boost

you are probably running lean which increases cylider head temps and melting stock cast pistons.

I would check out the your fuel pump then go from there. But a stand alone would be A good investment though.

Do you have a Egt gauge? I think that gauge would be the one to tell you if you are about to melt your pistons or not.

take it to a dyno for some tuning.

Have you considered hp coating? It will afford you a little more heat tolerance.
Hope things work out for you.

You didnt mention if you had any kind of FMU or rising rate regulator. With that small turbo on 10 psi you shouldnt be running that lean. How are you controlling the 380 cc injectors? those shouldnt run on a stock computer.
