Went back to super after seeing how badly the ScanGauge "thought" this tank was (24.6 mpg) when in actual figures, it was not.
Added another .25 oz on Syntek.

This tank was a beater tank. I had overdosed it with Syntek and romped on it a little. Not expecting good results.
This fill-up used the appropriate amount of Syntek (5ml for the fill) and I will try to get some decent mileage out of it.

This tank had Lucas Oil fuel treatment. This tank marks the end of my performance map on the Suby's ECU.

This tank to be, will be on the stock map with regular fuel. This tank will serve as my baseline to gauge the fuel treatment I'm buying from Kay.
