Remember that if you run too lean it could be hard on the engine, ................ especially with trailer towing. Try to reach that happy medium. Hope you have an engine temp. gauge.

My approach is going to be to put on the exhaust and then take the puller into the carb guy with one mandate. Do everything to fuel flow and vacuum to increase gas mileage. He is a wiz and has already told me that he will set the carb on the margin to get a couple of miles more per gallon. That might reduce performance a bit, but as I mentioned the truck is so hot at the low end that I could sacrifice a little performance.
