The best longevitiy for N54 is with Stock Settings!

I actually think the jb3 is safer since it remaps fuel and other things too as opposed to simply raising boost...

A JB+ is not safe. It just raises the boost. Get a different tune or stay stock.

Its actually very true! Even though a jb+ doesnt raise the boost by much, it relies on the cars stock ecu to add fuel, however the car isnt supposed to see more than a maximum of 8.5 psi stock so thats why a real tune us much better since it remaps all of the neccesary parameters.

point being the stock car is not meant to run 14psi with stock fuel/ignition. All the jb+does is adds ontop of whatever boost you are running. So if a stock car, like the guy in the desert, runs 10-11 psi in shit conditions as the ecu attempts to stock like power, the jb woul dsimply add on top of that 10-11 psi, which in those conditions is absurd.

this is why i was asking the question. i thought the jb3 would be a safer tune. but i emailed Terry from burgermotorsport and asked him if i should get a jb3 for longevity reasons and he said no the jb+ is ok. he would have made more money on another sale if he told me to get the jb3 but he said my jb+ was fine for longevity, im not saying it will last as long as a stock car, but it will make the car last as long as the jb3 will, is what it seems like.

Having cars with mileage on the JB+ and no failures is necessary but not sufficient to prove this is a safe tune... whenever you want to raise boost, you want your tune to remap other parameters to account for this additional boost (and not rely on your stock ECU)... just my opinion |

Its definitely not the only way to raise boost, but it makes sense to say that it is a safer way. As in a JB4 running at the same boost as the JB+, is a safer tuning solution. Would you agree? |

I agree that there are many ways to raise boost in the N54 engine, and you should contact to appropriate people to discuss safety.

And I told him to talk to someone more knowledgable them myself? I don't see a problem with that.
