Just know that a flash is an insta-loss of your drivetrain warranty now. I am not saying that you should or should not care, but BMW no longer has to hunt. The new ISTA auto-flags, so it is no longer a question of "if" your drive train warranty is void. https://x3.xbimmers.com/forums/showthread.php?t=1742168 I personally don't think we have much to worry about on this platform, but some do. |

I will be soon. Should have my '21 X5 M50i in about 4 weeks. Will install one after ome break in and give a full report.
I just traded a few posts with a guy on Rennlist who used a JB4 on a late model 4.4L tt V8, 5 series sedan and raved about it, said there was a big bump in power. Ya gotta figure 4 or 5 lbs of additional boost is going to kick ass on 93 octane. |

Have you looked into it?
Hi
I have contacted DME and Velos. DME offers stage 2 ECU tuning for around 1800$ for 80-100hp gain. But you can get a raceship at 699$ for a 50hp and 100tq gain. Now; why pay almost 1000$ for a 30hp gain? |

The mega down side to flashes is the instavoid on your warranty now. With the most recent ISTA changes, you have no chance to retain power train warranty. You will be flagged and BMW will know. It is all about what is important to you. |
