I had my 3.90 Motive gears installed over the weekend. And anyone that is on the fence about 3.73's or 3.90's, I recommend the 3.90's whether you do lot's of Hwy driving or not. I haven't yet recalibrated my speedo (debating on speedcal or Diablo Predator), but on the highway I keep up with the flow of traffic in the fast lane (70ish miles per hour) and I'm running about 2500 - 2700 rpm in 5th. I haven't yet been able to really lay into it, but it really pulls in 2nd & 3rd with just half throttle. Just my .02.
