I actually have both collectors on mine tapped for o2 sensors. It would be a litte pricy, byt I thought I would add another o2 sensor and a A/F ratio guage to help dial in the ECM.

On the Dyno the Air/Fuel is read from the Exhaust, If you want true accuracy from your air/fuel readings the need to get it from a wide band O2 Sensor setup, The LM1 is a little pricey but you will be able to tell if your running lean on the highway, city driving ro running wide open. There are lots of narrow band setups out for cheap money but the acuracy of them isnt there because of the slowness of getting and relaying of the info..


Burt, How are you getting a 30% driveline loss? Manual Trans setups are around 15 % Turbo 350/powerglides are about 20% which most claim is all automatics, and the Turbo 400/and 700R4 have about 25% loss
