Did you have to do a computer reflash? What are mtx wieghts ? What track? I have a 151 2.4
Your Polaris dealer has a reflash in their digital wrench system from SLP specifically for the SLP pipe and can. It works great. However, it will instantly negate any remaining warranty you may have. And since it is online, Polaris instantly knows that you did it. There is no way to hide it.
My riding partner has an '05 900 with the SLP pipe, can, head, airbox, torque stops, and "mild" port job. It also has V-Force reeds and a Boondocker Nitrous system. With the SLP mods, he hasn't even run a full bottle of N2O through the sled. No need for it. That sled runs very, very, hard. The only drawback that he has is he continually breaks primary springs. Three rides is about all he can get out of a spring. He is using a spring from SLP (almond, I think), but I believe that he is going to go back to an OEM issue spring from Polaris.
