Is there any solenoid bypass to speak of with the n55 motor? I know that was popular with the n54, don't know if there is an equivalent here.

Put my jb+ in. Took it for a drive.. Def noticed a difference right away! Took it local and highway. Went over 120 on highway run, tried automatic, auto with sport, manual mode, and manual with sport. Left jb+ on default settings. Very pleased with it! Gonna see if it "learns" and if there is a difference after a few days. No codes (visible at least)

Sadly, no real difference in performance in my opinion, just more turbo whine. Perhaps needs more "learning" time....
There should be a significant difference, especially past 2.5-3K RPM, like the review below.

pointless!

Hi Mike, I am new to this. After reading all these test result, its really tempting to get one. Unfortunately I don't have the M series. I have a F10 535i. Really want to try put one in and see if it makes a different.
I have a few questions may be you have answers for me. For JB plus, does it require a minimum of 91 octane, here in los angeles I can hardly find 93 in my area, is 91 will still work ? Should I just leave the dial on default settings? If I adjust the dial to the max or 3'Oclock position, I will need at least 93 octane to make the car run properly.

Right now my car drives fine just not happy with the gas throttle, I did use the sprintbooster a while back, it was fun and totally remove the latency from the throttle. Would this JB+ give you more responsive throttle like the sprintbooster does. I always feel the low end torque is very weak. When lights turn green, I see these Prius, Hyundai .. go pretty quick from start LOL. (or may be I am little easy on the gas, just feel why others are faster than mine).

Any feedback or answer will be great. I really want to try one and see how fun it will be.

You can run default settings if using 91 octane and will definitely make the car feel much more responsive.

Hi Mike,

Thanks for the reply. When you said responsive, does it mean the gas pedal throttle response will be sensitive like a sprintbooster?

My other concern is what if i set the dial to 3 O'clock position (Not Max), would I be able to use 91 octane. I have heard people set it up as max but have to use 93 up octane for the boost. Otherwise the car will have problem. Is that true ?

I just want to gather all the information before I make the purchase.

Regards
Ced
