I am running map5 daily, and a custom map 6 from BMS for more boost and more power.
I’ve bought a BMS Intake. Going to install in the next couple days
So by then I’ll be Tune Downpipe intake and E30
What else is there to do? Exhaust? I was never a guy to put exhaust on my cars, was always catless downpipe. And if I wanted more sound just do a muffler delete.
What’s you’re guys input on this ? Is there any one running the same mods but more E85? Maybe a e 50? E60? How much e can we put in these cars using JB4?
I feel meth is too serious also on a piggyback tune
What’s the deal just put more e? E50?/E60? LMK what you guys think

E30 is pretty much the limit with JB4. Before going femto unlock, I ran a jb4 for over a year, and did a quite a bit of logging and worked with burger and an independent tuner. What I found was, anytime I tried going for ethanol greater than E30, the car would run lean. I eventually grew frustrated with wanting more power, but being limited, so I finally gave up on it, and just went with the unlock, and boy its best thing I ever did.
