I’d love to see a JB4 non-S dyno chart compared to a stock S.

I've had no issues with launch control, 2nd or 3rd gear pulls whatsoever. I started experimenting with map 4 today using E30 blend as recommended by BMS (no CPI kit). I feel like the car is still trying to adapt but it sure makes serious power compared to map 3. I'm now spinning in 2nd gear WOT. In fact, this was the first time traction control kicked in 8 months of ownership. Kudos to BMS.

Hi Navid,

Thank you for the kind words. I'm happy that you're loving the JB4 system and the new added power. Since you have 93 octane, you can do less than e30 blend to relieve the system because you have higher octane to compensate. Send me some logs on map 4 so I can check it out.
I want to make sure the fuel trims aren't maxed out.

Very interested in Navids map 4 results with the ethanol blend. What blend would you recommend for those on the east coast with 93 octane for map 4?

Look for an AWD
