Tuning while on a lease...
Hey folks,
Driving a 2018 M240i Xdrive over here, and I am looking to get a bit more power out of it. I have read a bit about different tunes available, but I was curious to get some opinions on the best invisible tune. What are my options for easy install/unlikely to break the car/easy removal at end of lease/if stuff breaks. I know several companies offer warranties, but not sure how these apply to leased vehicles? Also wondering if you think it's worth running by the dealership first, or if these things are pretty problem free. Thoughts? |

Dinan and JB4 piggybacks are likely your best bet. I've read many people say that Dinan warranties are no longer a thing...but others have said otherwise. You'll probably need to call Dinan and your Dealership to confirm if A) warranties via Dinan are still available and B) you can run one on a leased vehicle. My guess is no. With all that being said, many many people (including BMW SAs I know) run JB4 on leased cars without issue. It is very unlikely you'll have a catastrophic issue that will cause BMW to dig into the ECU and discover evidence of a piggyback tune. Just know that it is possible though and it's a risk you assume.

Been using the JB+ (stock settings) for 2 years now on a lease and the SA never said a thing. But, if something happens to the engine because of the tune, the SA will not be friendly.
Best bet is to remove the tune before your service - jb+ takes less than 5 minutes to remove |

JB+ / Jb4 is the best option for leased cars
