puuuuufst, no need to spend hundreds of dollars on something like that for a mild street car. get a vacuum gauge and a good timing light. That's all you need. If you choose to stay w/ the Eddy carb buy the tuning kit. The Eddy 750 will never be as good as the 850DP. Personally I'd use the 850 and get a drop base so you can use your air cleaner assembly. I'd also turn the fuel line backwards towards the fire wall, or get the split fuel line. It's not rocket science.
to tune a car to run good, no. to FINE TUNE (get it running good and optimize mileage) yes. if you tune for max vaccuum, 9 times out of 10, I bet it's tuned slightly fat, and you're sacraficing some fuel mileage. for someone who drives his car every day, a 2-3mpg difference can add up relatively quick.
