Not sure if that is normal AFR for the kit but it sounds awfully lean for real world running.

He is probably being cautious because he knows that the AFR from a bank of four cylinders at the exhaust collector is the average of the four and since all cylinders are not the same identical AFR some will be leaner than the average and some richer. Its the leanest cylinder that you have to be paying attention to.

Did you ask Dustin Whipple if that is the case with his Stage 2?

I was told 12.8 at wot and around 13.5 mid-range cruise, Dustin at Whipple told me 12.5, I think he's being cautious.
My main concern now is cleaning up the idle/low rpm's. That is where most of my transom soot comes from. I notice a huge difference when I run the exhaust through the leg at low rpm's compared with running it straight out.
My stock flame arrestor is long gone. The Hardin Marine arrestor seems pretty good, I took out probably three-quarters of the stainless mesh (left two layers in) - I also took a grinder to the inside of the little velocity stack on the arrestor and smoothed out all the edges.

Innovate LM2, Logging of GPS Speed
Anyone have success logging GPS Speed into an Innovate LM2 Analog input. It appears the GPS device output digital signal would need to be converted through a "Digital to Anolog Convertor" to a 0-5V non-pulsed linear output. MPH to Voltage calibration numbers would also be necessary.
