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
