I run 20+psi all the time and DD my TR in the summer. I use about 10 gallons/year with a LOT of passes at the strip in the 11's, so roughly 1 gallon per 1,000 miles of driving with plenty of street runs and a few passes in there too. I never like to even see my low light flash. I try to keep it topped off at 3/4 full or more all the time. Alky pressure drops with fluid level and we have a lot of hills so sloshing can be an issue too. I should just get a cell. I turn my pump on sooner, 5psi, but with less initial and an agressive ramp. And Razor's kit keeps adding up to 30psi. His pump is also not maxed until the initial and gain knobs are maxxed and you run 30psi, as far as I know.
