BLueJAy432000. I was wondering if there would be a way to get that spreadsheet sent to my email at the house if i gave it to you. It sounds like you have one hell of a research project goign on and just curious to see the results.

 

I run 97 octane here in the UK, mine is a 6.8 v10 Whipple Supercharged dually, I thought it was safer to run the highest octane especially as I'm forced induction, but now wondering if maybe I should use our regular 95 octane. as 97 seems overkill!! (plus we pay £4.50 a gallon which I guess is about $8.00 !!!) ain't no fun when I only getting 9-15 mpg but who cares
