Not surprising. "Stale" gas usually passes. If you're "close", the problem is getting fresh gas to pass in 80 to 90 degree heat.

It's possible to pick up ET slightly by changing fuels , even brands of fuel . The pick up could come from increased torque , increased power , better throttle response , or a little of all of the above . Usually , any pick up you see will be due to the new fuel being a little more compatible with your engine specs and set-up .
And yes , some brands of race fuel are a lot more expensive than others. But spending a lot more isn't really necessary . Compare race fuels that offer the motor octane you need .

Mike you are absolutely right. If you have a car that is a 9:1 or 9.5:1 it is going to be less sensetive to fuel compared to a motor that is 12.5:1.

Our motor is 9:1 and I'll be willing to bet we could get it to run pretty good on a fuel with a lot less octane rating than 110.

In my 12.8:1 540 I have not seen a difference between Torco, Rockett, or VP. I did give Q16 a go but don' think I got the tune right and didn't see gains.
