U.S.

I don’t use the gas engine enough in my daily commutes at the risk of voiding warranty

I'm from Europe btw. Car has no longer warranty so I will try it next week. Honestly, in 90% my wife uses the car for very short routes so it is used as EV mostly too.

So I got some info from the company:

tuning box, you will have the option to change between 5 settings, A-E.
Adjusting the settings on the box will look as follows:

A: 469hp/705Nm
B: 479hp/710Nm
C: 487hp/720Nm
D: 501hp/739Nm
E: 510hp/750Nm

(B58 - 45e)

I installed the kit 2 days ago, it is really plug and play, nothing special. Only problem was with the boost sensor plug, the original. I was strugling with it for an hour to disconnect. That plastic had some issue.
I made a test drive, it is different for sure. On Bluespark module I changed the settings to A, so to the weakest. It is enough for now.
It would be good to test it on a dyno. Now I can only feel the torque change, and this modification is really significant at lower RPM.
So for this price this is a bargain.

I think I’ll install mine this Spring

I just picked up a used '21 45e a week ago. Looking forward to adding one of these piggyback boosts and perhaps an intake down the line. These cars are so quiet I'm not even sure if I want to do the intake or not, any observations?

I did/do have a 530E that I added a Racechip piggyback to ... don't know if it's related but I did have some transmission issues down the road and was replaced under warranty, a shifting hesitation when transitioning from electric to gas. Hopefully unrelated to the mod and just a fluke (I had read about someone else with the same transmission issue who didn't report having added a boost mod).
