It’s no surprise that gas prices are going up. So I’ve been looking into improving the gas mileage in my Evo IX. Between the variable cam, Timing, and AFR. I would like to get any advice to what people have been seeing that works. Also AEM doesn’t have the EGR valve connected. I will be doing that this weekend and post some results.

I’m running as lean as 16.1 at 3-5K in vacuum. I’m going to start to mess with timing and variable cam.

Open to input.
