Terry, well what is there to say that hasn't been said already, but for All those out there who are looking into tuning there BMW, N54 and N55, this is your guy (this is my opinion due to that I have the JB4 ) talk about support, he is there to answer your questions and today ( Feb 10, 2012 ) was no different if emailing or on forums, he was supportive and patient and we had a great day, well at least my wife and I did. ( Terry or Mike can chime in if they want )

Here my info

2008 535i E60


JB 4 - Alpha Firmware 2-7-2012


Eisenmann Exhaust: Race


91 Octane - 40% ( California and there low octane, BOO !! )
E85 - 60% - just going by there quoted 105 octane, so don't hate on me

For this Dyno:
When I fueled up I had around 1-2 gallons left, when I added 9 gallons of E85 and 7 gallons of 91.
