Ran my chip on the 100 hp setting...just because I could.
Handled the hills great, engine ran a bit quieter, rpms and EGT's were down some. It's running about 75 degrees cooler over all I'd guess. RPM's were down about the same, 50 to 75 less than before at the same speed
Held it to 67 or so the whole way, rpms were about 1900, mileage was 16.1. I was hoping for more, but don't we always?
Next test, full week at 80 dd.
What a difference!
