I’ve had it for over a year and the power bump is noticeable. I recently removed it just to see if I could feel a difference going back to stock and it was certainly noticeable.
Very nice, I use dragy, which 1ft rollout is taken away from results (does show with rollout too but it's not calculated for validity)I’ve had it for over a year and the power bump is noticeable.

Take these numbers with a grain of salt but before the install, I was getting between 3.8-3.9 pretty consistently.
With the JB+ I am getting 3.5-3.6 consistently.
No driveability issues at all. I keep the dial in the 3 o’clock position and use 94 octane fwiw
Good stuff. Do you have the JB+ at the 3 O'Clock position or maxed out?I’ve had it for over a year and the power bump is noticeable. I recently removed it just to see if I could feel a difference going back to stock and it was certainly noticeable.

Bang for buck I don't think it can be beat. If you are expecting it to be mind blowing then no. It a good compromise for tired of stock power but don't know what route you want to go yet.
What other mods you have?I’ve had it for over a year and the power bump is noticeable. I recently removed it just to see if I could feel a difference going back to stock and it was certainly noticeable.

At the time these pictures were taken only cosmetic mods. I now have an AA downpipe, too.
Its a pretty basic device. Just under-reporting your boost pressure and letting your DME compensate for fuel. Only downside is occasional hesitation when the DME can't compensate quickly enough.
I agree, something I can get behind.
Hmm I do get the occasional hesitation. Can you explain more about this and would it be worse at max setting?
A few occasions I have been driving and noticed with constant throttle % (around 60%) in 3rd, the additional power would surge on and off a couple times thru the revs. (almost like the tune flipped on and off) This was with the dial maxed out and 3 gallons e85 mixed into 93. It hasn't done it the last two time I've driven it.
Carguy not sure what you are experiencing is JB+. Try unplugging yours and see if you get the same issue with shifting at redline. I have had mine at max for over 2k miles no hesitation at redline shifts. I have even tracked the car twice now with JB+ no hesitation or issues at all. I have been using 93 no e85 so far. The fuel compensation adjustments are written in to a long term trim map after a pretty short period of time. There shouldn't be any hesitation on the DME's part.
In your case I would be concerned you could be nearing the max flow of the injectors with that much e85 mixed in. I would consider backing down on the e85 content only. There may be no real need to back off the JB+ setting.
