You wanna try something new run E85(30%)/ 93 octane(70%)
Change ign. Correction to 0.
Huge difference, you'll like your procede all over again.

I burn the N55 and the N54
N54 (Jb4, dci, resonator delete): Raced him from everyway possible. Dig, 40-100, 60-120. I beat him everytime.
N55 (JB4, bms dp, pe, drop in) beat him from a dig, on the freeway, pretty much always. He walked me once because i had a passenger, he did not, and he was running high octane. His excuses: " i was only on map 1" "my traction control was on" and some other shit.

Wait so you can put e85 and 93 octane? You can mix it up? There's e85 fuel next to my house I didn't know what the hell it was lol. So if I put in a little it will make a difference in performance? Is it bad for our car because I know ethanol is not good for boats.

Yep put in 4 gallons of e85 and the rest in 91 or 93. You'll notice a difference

I've been running JB4 for about 5 months now and I wish I could say the same.
Zero mods other than the tune (2011 e90 n55 6mt) and about once every few weeks the car will shudder while cruising at freeway speeds.

I like JB4, but please don't qualify their quality with a statistical sample size of 2!
