I ran an 11.7 @ 117mph and was on the JB4 G4 15ohm board and RB's, using about 2.5 gallons of E85 back then...Curious to see what I can cut now since I'm running the JB4 G5 ISO using about 5.5 gallons of E85/93. Good luck and cool your new tune is working out for ya  |
Thank you! And as soon as we fix the small details I'll repost updates.
