How do you spell Road Dyno...

This proceedure can help with the tune. It is for setting fuel pressure, but if you change ONLY one thing at a time, it can work for any variable or adjustable item.

Get one of your buddies to ride along with you. Find a level stretch of road where you can do some testing. Don't choose a speed range that will make you shift gears, the shift quality & speed will affect your results. Use 2nd or 3rd gear and do a run from 2000 RPM to 5800 RPM. Call out the RPM as it increases and have you buddy record it and the elapsed time. If you have one of those cheap digital watches like I do, a stop watch is built in. Start the fuel pressure at 36 PSI, vacuum off and make a run. Turn it up to 37 and make another. Be sure to reconnect the vacuum every time you set the pressure. Keep turning up the pressure and making runs until you notice a drop off in time. If your bud was careful to record the results, you'll have a nice chart to use to find the optimum pressure.

If you can find a G-tech to borrow it makes jrichker's suggestion easier.

well if you could tell us the exact parts list of your car then we can suggest a fuel pressure and timing setup for a good tune.
