740 tic is slugging out when the boost comes on.... 700

Hello...the car is running fine at startup, idle, and throughout acceleration..until you try to put the boost needle near or above 12:00.

Then, I watch the tach start to drop, some black smoke come puff out the tail (not too much) and I don't really go anywhere.

I replaced the Fuel pressure reg., for fun, didn't help. I'm pretty sure the turbo hoses are all good, I recently replaced them with better ones.

Should I swap an AMM or power stage?

Any other places to look would be appreciated!!! P.S. I've had a good stare through the FAQ, but I'm curious to what the brickers out there think.

Thanks! Josh
