[7isPerfect]

Hi,

I have '14 650xi gc (nt63tu)

i recently purchased a jb+ and its on its way but wanted to know how much of power i would be getting on my car.

it's pretty fast right now but i was hoping i would get some more power with this affordable purchase.

if you have any experiences please let me know!
thank you

Yes, I have the JB+ on my GC. Ehhhhh, I did before and after dyno tests and I got NOWHERE near the advertised results, I got 25WHP and I had to turn up the set screws inside each box past what is recommended in order to get those numbers, I emailed burger tuning and they told me to turn it up until I got advertised power and I tried but at mark 7 I got 25 and all the way up I got 26 so I turned back to mark 7 and left it alone.

I am not sure if JB+ is the same thing as the BMS Stage 1 tune, but I had that on my N63tu 650 and it did absolutely nothing so I sold it.

According to BMS, some N63TU cars did not adapt to the tune is what I was advised from them when I contacted them.

When my warranty runs out, I am going to a custom tune or JB4 as that seems like its the best from what I've heard and been told from multiple people.

The problem is that nobody ever does an actual before and after dyno with these cars. Since my post I have met two other N63TU owners and convinced them to do the same before and after pulls and hey "thought they felt the difference" then they saw the actual numbers and were both very disappointed to say the least. Don't get me wrong I had an increase in power but not what I expected and nowhere remotely close to what was advertised

Seems to be a commonly reported problem with the tu motor. Just doesn't take. Sounds like the flash tunes are a better option. Much better numbers anyway, - +100 hp and torque.
