Yeah Mark even with your old Fuel i ran my Go Tech at 135ish and it produced awsome power. Worst part about it was the clueless idiots telling me its too hot and i was gonna blow my engine up.
I had run it a few time at 140+ but didnt gain much, anything under 120 and it was doggy.
Go Tech`s love the heat and thrive on it, i usualy leave my temp gun in my tool box and tune by ear.
Might try some of your new improved fuel soon.
Deanos car seems to run pretty strong using it.
