Just picked up a nytro with a stage one mpi kit. It has a 23 top pulley and 31 bottom pulley...what boost is this at?
Also, I believe the fuel settings to be; 1.5, 5, 6, 6, 3, and 7. This was taken from the MPI manual that they wrote in. Unfortunately i have the plugs out of it and tank off so I cannot start it.
However, I rode it only a mile or two and noticed the A/F numbers to be in the 15 range (lean!!).
I am doing a compression test tomorrow once I get an adapter for my gauge.
Any help would be great!!

big pulley on the crank (bottom)
small pulley on the S/C shaft (top)
should be 11psi - measured between the throttle bodies and the head - measuring in the intercooler will give you higher #s
