Any Tuners on here?

Im using Magic Motorsport Flex and X17 with good success. Ive only ever had one problem and thats with a 2019 BMW X3M40i where I couldnt write a gearbox file due a lack of some sort of data from BMW. Some customers Ive met say MHD is a simple option because it comes with preloaded maps. To actually make modified maps most are using either WINOLS or Autotuner. Theres a new program called Stage X out there now from magic motorsport but Ive not used it and couldnt honestly say if its any good.
