No, I never dynoed it as I have stock fuel injectors but not a stock fuel system.  As for the ecu bit, to run a '91+ ECU in a '90 car requires the gauge cluster (tach), coil packs, and power transistor from a '91+ as well. So the '90 is a more versatile ECU as far as swapping.    
My ecu is the eprom ecu.  I was going to send it in since the transistors were done recently and the DSM link was the last bit I needed to open it up.   
And...   
No trades.
