BMW G90 & G99 M5 913HP Stage 1 Performance Controller

GREAT PRODUCT!!

Was skeptical but the dragy results are irrefutable

I’m always skeptical when only Dino numbers are posted to show performance games for any type of part tune, etc. , but given the reputation of the owner of the company I said why not I’ll be the guinea pig. And I am glad I made that choice because the car drives significantly better than it did in factory form just on the 93 octane tune previously the transmission would seemingly take forever to get into the next year and fall out of power, but with the new tune everything feels so linear and smooth, and the transmission shifts instantaneously into the next gear and the results speak for themselves. I was beginning to have buyers remorse for my G 90 M5 but honestly this 30 minute installation of a box and a couple wire wires has made me really like this car and I’m finally impressed with it. This is how the vehicle should’ve come from the factory. Curious to see how the 100oct goes but I’m in no rush. Can’t wait to see what suspension parts. This company comes out with that hopefully fixes a lot of of the handling issues I have, which is next on the list of things I hate compared to the previous generation M5.
