It feels as if this car/model is getting Performance Upgrade offerings by the week! And the price of this is absolutely ridiculous nice. Anyone here interested?

Looks great. You should order it. I've had the JB4 on my G90 since Jan 23. My redstar downpipes arrive today, install tomorrow. I'm also in the north TX burbs. The dyno he is using in the video is completely different than what you will find in our area. His Dyno is reading very high, not realistic. The cars are 780 crank from the factory. 20% drivetrain power loss, so a real number on a dyno is 650-660 HP. The best Dyno machines are Mustang, in our area, JoTech and AWD Performance have them. My car showed 652 stock wheel, 782 stock crank. 749 JB4Wheel, 898 crank. With downpipes you can increase PSI and run an E85 mix, so shooting for an 830-850 wheel HP with custom map. I also have an XM, and may give it the same treatment. If you want to connect and discuss since we are both N-TX, let me know.

I’d be interested in connecting with you as well. I’m in North Dallas and thinking about ordering the JB4 as well. Had it on my G80.
