Econ shouldn't matter at cruise with the fuel. It's setup with timing, on cruise I recall that timing is advanced quite far. You're talking maybe 2-5° of timing difference for the 87 to 93 fuel.

I dyno'd my truck and found around 16rwhp at the high end with an extra 5° of timing.

Anyway, hope that info can help :jester:
