The tires are not rated for that speed. There is a guy in Ft Myers, Proautoman is his sig on titantalk, how does ecu mods. He may be able to lift the limiter with an ecu mod. Its something like $420 but it also enhances performance and can be updated for free as you continue to mod. Several Titantalk guys have had good results. If you do this, get better tires, V rated at least. The Mada/QX isn't designed for these speeds. The Bimmer is designed for autobahn use, very different. You don't want to blow a tire at speed in a large SUV. There's a video of a suburban doing this. They guy was going about 110 and lost it. Fatality. He ended up being flung from the cabin and the burban rolled over him. Bad news. I have no problem going fast. I've broken 160 in the vette and cruised for a couple hours at over 120 but I don't generally break 95 in the mada. No nead. Its not meant to be a top speed monster. Next time I'd just rip the guys up at the lights.
