Had the jb in for a bit now. Decided to add 2 gallons of e85 and see how it goes. Has anyone turned the jb up at all? And if so how much did you go for what supporting mods. I hope terry makes this into a Jb4 type soon, would love some auto tuning!

 

Several JCW and GP2 guys using this.
But they all hang out here: https://www.northamericanmotoring.co...ms-tune-s.html

Terry is there also, not sure I've seen much chatter outside in the model specific forums.
Just saying your best bet is to read and hangout/subscribe to the JB+ thread!
