220i Tuning Advice

Hey guys I have a 220i F22 2016 i was wondering if anyone knows and can help me regarding what I can do to make my car faster without voiding warranty.

I already have an aftermarket exhaust so I won't be doing any mods to that.

Been searching on these forums for the N20 tuning but I prefer to hear from some people who have used the JB4 etc themselves and warranty related issues

If it's possible could you link me so i know where to buy what you recommend

Thanks everyone!

JB4 doesn't void warranty, or just easy to remove if s/t goes wrong? I thought anything that was modifying original system was potentially a problem?

Easy to uninstall, takes 30 minutes

You are correct, any mod can cause issues if the dealership want to give you a hard time.

Thanks for the clarification - figured these could be an issue, but always hopeful (and nothing like the ECU redo's, in terms of difficulty switching back to stock). Not really bored with it, but thinking of some changes - you can tell the extended wait to get summer tires on is starting to erode my self control....

Any tune will void your warranty. You can remove tuners like the JB4, but BMW can see that you had it on there. They can look at things like boost pressures and see that it was running above stock.

No matter how good a relationship you have with the dealer it won't save you from BMW. If you blow an engine BMW will likely send out their own rep.

Looking at some other posts about blown n20's due to timing chain failure, you are looking at $15-20k for parts and labor for a new engine.
