Racechip v JB4 for a '19 540 w/M package (if that matters)

deciding on one or the other. both are 50hp upgrades, allegedly. racechip is about $80 cheaper just not sure which is (a) better and (b) easier to install - both should be fairly simple. Anyone else gone through this that can offer advice? my car is a lease but I'm one of those "I don't care, I'm doing it" kind of guys... thanks!

or...do I go with BM3 (bootmod3)?

I wonder which mixed review?
I don't recall selling a lot of RaceChip to G30 540 guys.
But, I have sold a lot in F15/F16 X5/X6 all engine variant, F85/F86 X5M/X6M, and recently F90 M5.

I know you are a reseller of Racechip, thats cool, but dont try and play coy.

Anyone else thinking about Racechcip you should just google "racechip reviews bmw". Then just sit and read the negative reviews for a few hours.

Curious too about DTE, as the other options are not popular in Europe. DTE was the one present in Germany/Austria/Romania. Anyone has it on 540i ?

I thought that once you flash the ECU it's permanently marked and traceable. If so, then it's not an alternative to piggy backs like JB4/Racechip and carries a much higher risk of voiding warranty.
