Sweet. My 86 GN just passed yesterday here in Delaware. We do a two speed idle test here.
My numbers were:
HC (PPM)
Low: 2
High: 0
Limit: 220
CO(%)
Low: 0
High: 0
Limit: 1.20
Car has 50# MSDs with TT alchy chip with open loop idle. Used a stock DP and low mileage cat for this test. All I did was turn the static FP down to 32psi. It worked. EGR is removed and blocked off.
