I have not seen much improvement with the pro jection system but it did make the engine much smoother with better drivablilty. My old roomate and I had a fuel milage war some years back I had a 440 truck and he a 350 chevy truck. I used a lean carb and he put the holly the fuel milage was neck and neck. We were getting 17.2mpg with both. If I could have put a 700R4 behind the 440 I think he would have lost..
2.73 gears with a O2 that was way lean worked great on the hwy..
I like the way the megasquirt is set up and I am sure it will do all I am asking of it.
The suzuki uses Mikuni parts..
