I installed the SLP pipe and can during fall of '06. SLP had just just begun to ship the actual product. Didn't ship any during the 05/06 season. At that time, the ECU programing had not been released by SLP to the dealers, allowing them to use the digital wrench program (like they did for the 900's). As a result, I had to pull the ECU out and send it to SLP with a copy of the receipt for the pipe, and the color of the injector sleeves. No problem, very fast turn around (one day). Very easy.
The biggest change to the program is at higher RPM (7000 to 7400). The motor takes off, like a motor with twin pipes.
Not sure if the program is the same for 700's and 900's. i would think the 900 needs a bit more fuel. The ECU box itself should be the same. You can then reflach with what ever program you want.
The best part is you loose a true 20 pounds from the front end. I made the change for the weight savings alone.
