Why can't you mix E54 + some 91 to dilute it? I run something like 4 gallons of E85 (min E71, per pump sticker) + rest 91. Based on this:

~5.6 gallons E54, 6.8 gallons 91 will give you E30. A 50/50 mix of E54 and 91 will give you roughly E32, which should be fine.

I wonder if, with the CPI kit + HPFP, you could actually run E54 straight?
