I have HKS adjustable cam gear sprockets that are both set a 0degrees. I guess when I said built I didn't mean I was going to take away my power to gain fuel economy, that would be retarded for this car. A person doesn't spend big money to make power and then start retracting solid custom parts to gain small percentages in FE.
I have no belly pan at all as we speak. Planning on a full pan front to engine bay area and maybe between the motor area and the rear bumper but I need to leave under the motor open as the motor makes a lot of heat.
The exhaust is a full 3in with no bends but rather cuts welded back together, you can believe there is no back pressure. The back pressure only comes from the turbo.
The standalone Autronics computer was tuned to run around 15.1 afr at 3000 rpm area. It is fairly clean running at that range.
I could retune with cam adjustment for even more torque but I am not willing at this time to do that due to cost effectiveness. And as I said this car makes 181 peak lb ft torque at the wheels. I could only bring that down a few hundred rpm by cam adjustment.
