First JB4 G5 Datalog

Hi,

Finally decided to upgrade to the G5 board and wanted to make sure everything was running well. Also took the opportunity to change out the vacuum lines for silicone. Looking at the condition of the toasty OEM lines, there had to be a boost leak somewhere.

Noticed an increase in throttle response and overall smoothness. I encountered some rattle after the install but was able to minimize it by adjusting some values. Overall I am very happy.

I absolutely love this car, even with the light mods that it has it is faster than some FBO Meth cars that I have raced and a LOT faster than my Previous 08 335 FBO. It's a freak of nature, I really can't explain why it's so freakin' fast.

Info:

- 2,3,4 Pull
- Shell 93 Oct
- BMS JB4 G5
- BMS DCI
- Forge BPV
- UR Downpipes
- HPF 3.5" Exhaust

Feel free to analyze and comment on what you see.

Special thanks to dmacpro91 for developing JB4 OSX. Used it for the first time tonight and works like a charm on my Macbook Pro. He has an amazing app for us JB4 users that's worth a look JB4 Mobile.

It is not that bad.
But when the fp_l is suffering that is usually a sign of a fuel pump failure in the near future.
