quest for power... 09 800's

[F_ast]

Being totally satisfied with the performance from my 09 crossfire 800SP this year, i wouldn't be able to call my self a man if i continued to run a stock snowmobile. I have been looking into power adders and have pretty much nailed my direction down to 2 options.

1. RKT 15hp kit

2. D&D shim kit

Similar HP claims or true 10-15hp, but are there any options or clear cut direction i should go. I have looked into both and read some response but looking for a comparison of the 2.

Setup, fuel and additional parts needed to make these kits shine?

thanks

Get the slp or speedwerx pipe in my opinion.

dealer runs a 09 m8 slp piped, ported with a bd box and a stock 09 m1000 won't touch it,
