Big difference between JB+ & JB4 on a stock application
So I've tried a JB+ and I'm planning on either the Procede or JB4 route for my 335i 6mt. The JB+ was pretty cool, but I'm understanding that you can grab a little more power from the piggy back tunes.
What I'm questioning is the feeling difference of the JB+ vs JB4 on a car that has no other modifications but the tune? According to the Burger website, the dyno charts of a JB+ turned up to 100% have very similar performance gains as a JB4, all on stock applications. I'm sure people here with experience with these and similar tunes will be able to comment on this. Thanks in advance! |

The full tunes also are more feature enriched and able to control a lot more of your engine. The JB+ although a great so called "Starter tune" is hardly a tune its just a boost controller in essence. A full tune is actually a safer approach IMO as fuel and ignition can be controlled. If you need any help further I'm a PM/email away. |

Good call, safety is one of the main reasons I've pulled my jb+ off the car. I had a reflash done on my 2.0t vw and it really made an all around difference on the car. The feeling wasn't so all around for me on the jb+ (could just be mental). Is this what I should expect with a

With the JB4 you will notice smoother power delivery, more power and much more features. At 100% the JB+ is not that smooth so you will notice better drivability for sure, even if the power delivery won't be that different from map1 on the JB4 to the JB+ at 100%. Its well worth the upgrade. Mike |

OP if you just want more power for around the street and never race your not going to notice a huge difference. The power down low is similar up top is where you'll feel a little more. It's not night and day like some claim. |

I never said it would HARM your engine. JB+ at 100% is not recommended is what I said. If people read the instructions they would see this. (dont worry I'm not picking on you I just hate when people turn words around). Quote:

The first sentence was meant for you, second sentence was more of a general question for all those who say the JB+ can be harmful. Please provide some proof cause I've never seen it. I like to try things out so I've gone through the JB+, JB3, JB4, Procede V4/V5, and Cobb AP. Just trying to give the OP some unbiased opinion. It is not a huge difference, powerwise like some mention here. |

If so, isn't just like the JB3 was and the JB4 was regarding at least ignition control? So according to Tuner A, the DME was good enough to make the adjustments. Though now they have a CPS module addon. Now according to different tuners, some say the DME is good enough to make adjustments and some say not. But there is no definitive proof. If anyone has proof please post it up. Then we find out the stock DME adjust timing per cylinder. Tuner B (who I will not name but anyone who follows this would know), says their tune makes their timing adjustments off of cylinder 1 and the DME does the rest. So is this now saying the stock DME was good enough to make adjustments in the first place? Regarding B, Of course if you want to maximize performance you would go with an alternative that will allow you to get the maximize performance out of the car, but the OP is talking about a stock car with tune. |
