I havent had any problems with the JB4 communicating with the ECU and I have been tuned for about 2 years now.....So dont know where that info came from... So a 12.6 on NEW TUNE and NEW AA TURBOS....I know your wheels and tires are KILLING you in the quarter mile but with a upgraded turbo car I still think you should have been in the low 12's. 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
