Once again your just showing your mentality, you don't know that every high tech development is tested in a Cadillac before any other GM vehicle, magnetic ride control was first on a 2003 Seville STS before a corvette got it. You can't beat me on GM technology. I was trained at GM in Parma Ohio, I also have a degree in electronics from kent, so if you want to challenge me, whatever. You know nothing about engine technology, It requires a laptop? What a dumb *** remark, once again showing your mentality. How old are you 12? Northstar is 4.6 l that is 280 ci with a cam change, spring change, and good headers they can make 800 HP with no problem. Oh yea you probably don't know what magnetic ride control is so I will tell you, It's a shock filled with ferrofluid that has a electromagnet on it and it 's viscosity can change from a mineral oil state to a gel in 1 millisecond, that's the technology that I know how about you give me somthing technical. My mechanical limits are way past you. Go find a GM site.
