Problem with the reflash is that if you have a warranty left on the sled .... and the dealer does the reflash.... they must enter in the VIN # of the sled in Digital Wrench.... voids the warranty.
Now more than ever, Polaris is looking for reasons to deny warranty claims.
You could try it, but I doubt that it will do anything... if it did, the performace houses like Tri City Perf, Carls etc would have done it years ago.
my 2 cents
