Putting JB4 on

[dangenny19]

Just purchased my jb4 and had a few questions that I couldn’t find online. I have a ‘19 G70 3.3t AWD currently am running the burger motor intake and oil catch can, I also have a custom exhaust and midpipe. I was wondering what gains I will see with these mods? Can I run e85 on lap4? Should I still consider getting lap3? Any other suggestions would be helpful!

Hard to say what gains you will have without a dyno. The alternative way: got access to a Dragy or a drag strip? Do a 1/4 mile run and note your trap speed at the 1/8th and 1/4tr mile marks. Compare to your stock speeds.

With just the JB4, you can add E85 to your 93 octane to target an E30 mix. That will get you a lot of the octane gain while not asking for more fuel than what your stock HPFP can deliver.

If you want to go all out, here’s where I ended up (best value for $):
JB4 with Charge Pipe Injection (you have the JB4, CPI full kit is about $820)
BMS Back End Flash to be able to run straight E85 and take full advantage of the octane rating. $520 for the SXTH EK1mini needed to load the BEF, plus $75 for the BEF file. The EK1mini gets tied to your VIN.
BMS TCU Alpha flash for $75, and you use your EK1mini to load it.

Don’t bother with getting an ECU flash from anyone else, you’ll spend at least 2-3X the money for MAYBE a little more power.
