Can anyone tell me what to make of this datalog. I am having problems getting the car to run above 2800 rpm. The reading on the tach is eratic. I am running MSII 2.33 on a gm3.1 throttle body running 8-10lbs of boost any insight would be greatly appreciated.

Looks like your RPM signal is quite erratic. That will definitely affect everything........... WHere are you grabing the rpm signal from.
Timing looks ok
Fuel looks ok but your PWs are a little odd but those are impacted by rpms.
MAP does not seem to rise as the trottle opens up so something is up.
If you post an MSq it will help in determining what is wrong.........

There seems to be something wrong with your O2 sensor. It is spending most of the time stuck at .409V and never goes higher. This is sending your Gego to your min as it is always lean.
