(2)450 DP's vs (2)750 DP's

I’ve found over the time I’ve spent tuning the 750’s is 14.5 (by the gauge) at cruise is where she’s happiest. Anything much more than that she feels flat. Having the gauge is nice for seeing the outcome of a change. I use my butt dyno to gauge whether it was a positive or negative change.

Nice to see you posting and working on the Duster, Mark. Are you looking for better mileage or response? What MPG are you getting with the 750s? I am super happy with my 660's with a similar car set up and get 11mpg. Mind you no vacuum advance, no power valves, etc..
