Question Who is running the DUI ignition set up?

Who is running the DUI ignition set up and did you notice any gains?

I run the HEI distributor from CRT performance, its a DUI knock off. its one of the best mods I've done to my jeep and allowed me to get rid of the problematic factory emissions system. I've run it for 5 years with O problems.
like most performance mods its just one part of the package, add a better carb, a more open exhaust and you will see a substantial power increase.

I got the whole setup, cap, rotor, coil wires, opened up my plugs to .060. Noticed a little gain in power, big difference in fuel mileage. Very pleased with setup.

I have it on my '90 yj with a 4.2. I bought the jeep with it already installed. I have been playing a bit with the timing. Using a vacume gage I reset the timing and have been very pleased, better starting, power and mpg. Now it is time to play with the Weber carb set up and fuel pressure.
