So that’s roughly 4psi over stock. Max is 4.5 according to them. But my map 2 is similar to max on JB+ and that shows around 4-6psi over stock. Your car will be fine at the 3 o clock position.

The thing is, in my car, map two is putting out around 6psi over stock. So is map 3. Basically map 2 and 3 are the same in my car. Map 2 felt slightly more powerful so I went back to map 2. Ill be adding a few gallons of E85 in my tank and then run map 3 again and see if theres a difference

Map 3 was slightly worse than map 2 for me. Another person running JB4 mentioned the same on his 330i and hes running map 2 for now too. Stock, our cars dont produce too much boost. Around 13-14psi max. Its in the 11-12 psi range most of the time. With map 2, mine is pushing around 19-19.5psi max.

Well. I screwed up. I got the grey lock thing accidentally off of my TMAP sensor and it fell into the engine bay while trying to install. Idk what the hell to do. The TMAP sensor will also not come off. Help lmao.

Use a small screwdriver and slide it under the black tab (look at the corresponding/same tab on the JB+ to get an idea - the grey tab you lost rests on top of a black tab - slip the head of the screwdriver under that black tab). Lift the black tab up and pull the connector. It will slide off.

Putting my screwdriver in and the damn thing still won't come off. I'm also worried whether the grey tab falling in will screw up anything |

Nope. It wont do anything. Youre in the exact same boat I was in. Youll notice that the JB+ plug clicks in place. Thats all that matters. It will NOT come off unless you use a screw driver again to remove it.

Thanks to VipinLJ and g20beam for reassuring me that nothing will happen to my engine lmao. I was seriously freaking out that the grey lock that fell into my engine might screw up my front axle or belt in the engine bay. Hopefully nothing happens as it's very tiny. Okay, so now moving onto the JB+.
Installation wise, it was very easy to locate the TMAP sensor after taking off the engine cover, however, disconnecting was a pain at first. I was stupid and broke the upper tab and grey lock on my sensor and was only pulling on the upper tab rather than the bottom one to pull off the sensor. Later, I realized that I was supposed to lift the lower tab and then the sensor easily slid off. All I had to do was plug in the JB+ and we were good to go. I'm a little concerned about the location of where the juicebox is within my engine bay because it is touching very hot components of my engine and may melt some of the plastic on the juicebox. Ill attach a pic of how its situated within my engine. Performance wise, I was very surprised because most people said they felt a subtle change. However, with the thing cranked at 75%, I feel like I felt a huge change. My butt dyno definitely puts me back when I go WOT compared to when everything was stock. Past 3k RPM, I could hear my turbo spool a lot louder than previously on Sport Plus. I was easily able to hit 100 mph on the highway without even realizing it. One difference that I felt was that I wasn't getting the gunshots I usually get with my Y-Pipe Muffler delete on 3k RPM anymore. They only come when I rev it up to 5K RPM when the car is idle or when I downshift and it hits 5K RPM. Overall, I believe that the JB+ is definitely worth it for the G20 330i and I even felt that my car pulls harder than my older F10 535xi. My G30 540xi still feels a lot faster as it has the B58 though. One question I had was when I tried moving the arrow inside the box to 100% with a screwdriver, I literally could not do it. It almost felt like I was gonna break the little blue thing off the green board. Keep in mind my JB+ is used, so was it easy for you guys to move the small arrow inside the blue circular module or is it just tightly embedded in its blue shell? |

Glad you’re enjoying it hamzag20
In my JB+, it was relatively easy to turn the arrow. Only the white arrow part moves (the blue thing doesn’t as you probably know). Did you try using a little pressure to turn it? I don’t remember the blue thing moving or about to break when I tried it. And yes. It can get hot. The plastic box will have markings on it because of the heat but it doesn’t melt enough to become a problem and doesn’t affect the board inside either.

I was trying to unscrew the cover to crank up the boost and I also lost one of the screws into my engine bay, needless to say it was not my day I replaced the screw and all is fine, I was worried about the grey clip in the engine bay as well as my jb+ getting disconnected while driving. I was contemplating buying a new JB+, but after inspecting the connections, those are solid I think it'll be fine without the grey clip and the new screw fits perfectly. I couldnt find the screw or clip so I decided to drive like a bat out of hell and drift as many corners as I can to hopefully knock it out LMAO. I hope its gone, I tried tapping the undertray and couldnt hear anything LOL what a day. Was the plus .5 PSI worth it? HELL YES |

Anyone else notice the burbles are less pronounced after adding the JB+?
