Probably not 100% necessary, but it takes like 2 minutes to remove, so I am just going to play it safe. Especially since I don't really know how my local dealership service center reacts to any sort of modification. I have read some dont care as long as the reason its in for isn't caused by the mod, but I have seen post that some are more strict. So I just don't want to deal with them.

And also since they might note the presence on some log somewhere, such that if you brought it in for a problem, they'd know it had it. Potential future problems.

It's just not worth it in my book for 20-40 hp on an already quick car.

Do you really think it's necessary to remove it just for an oil change?
I would say yes asd the tech may note it in the car's file and then you have a possible future warranty claim denial. Some dealers are dinan authorized so you pay them to install and now they have to warrant any claims

I installed the JB+ today. I like the extra boost. I would say this is a good mod if you want to keep it simple, affordable and incur a slight bump in performance. S30i.

No offense, but answers to most of the questions you seem to ask in this forum are only a single Google search query away. |

I had a jb4 on my stinger for about a year. There are dynos showing it gives around 70 hp on 93 and up to 100 if you run an e30 mix. Looks like similar numbers for the b58 engine according to their website. Well worth the money, especially since you can find them used and resell if you want to move on.

It did, but luckily it was leased through my company, so the company paid for the transmission repair. I knew it would happen again, so I immediately traded the car in for an Audi RS5. Once the lease on the Audi ran out I went back to BMW’s.

My dealer just told me to have the Dinan installed at a local BMW Dinan shop to avoid any issues.

The installer my sales guy sent me to used to work at BMW and he said he's installed dozens of these when he worked at the dealer.

So as not to hijack the OP’s question, I have not personally used the JB tune, but have hear lots of good feedback on their product.
Warranty is always the biggest issue. APR completely abandoned me when I had problems with my Audi, but the issue wasn’t the chip. It was the transmission failure due to not being able to handle all of the extra torque. Today, I pretty much stick with Dinan. To Matthewstorm, if you can find a BMW dealer that does Dinan installs, that has to be the safest route for warranty coverage. I know that BMW dealers did this in the past. I’m not sure about present day. My local BMW dealer said that BMW is getting like Audi in their denial of warranty coverage for cars that show aftermarket work such as tunes. I think the Z40i with either the JB or Dinan tunes would be fantastic. That is the main reason I was shopping Z40i’s. I ended up getting a C8 instead, but the Z40i on a tune would be running comparable HP/weight ratio. |
