I said earlier:

Could all these issues be caused by bad ignition parts or a bad ground? Could that be why the pick up is bad too?
On a previous vehicle boost and torque would get choppy and taper down. Found out later on that my coil pack or something was bad.

And I found a dyno chart. Was running 17 psi but it would taper off to 14 psi. by redline. It got choppy too in the higher rpms. My tuner couldn't figure out why it was doing this as the turbo was BIG, no knock, perfect timing and definitely shouldn't have been losing boost. The car also had terrible cold/warm start up issues. We tried for months to figure it out and in the end I sold the engine. Someone bought it and put it in their car with a new ignition pack (something like that) and it ran beautifully. Made 420 WHP with no loss in boost etc.
(notice how it gets choppy at 5.5k rpm?)
