Between 1.5 and 2 gallons remaining. When in Street spec I ran entire events with fuel light on all the time. The only issue is when you try to balance that for full weekend events the gauge will not update until you have 3+ gallons more than what it's reading. If you continue to add 1 gallon at a time after every session it won't budge; presumably this is to account for different readings from parking on hills, etc.

If you tune the car I wouldn't run it beyond fuel light and if you're on a concrete site you should consider adding a little to account for the extra G-forces that might result in fuel starve.
