I know that RAW is based out of Canada and I'm currently saving to buy the RAW stage two upgrade for my 06 ss/sc. I just have a few questions before I buy.

Does your 2.79" pulley fit the hub that is on the car now (stock), or do I need a RAW hub as well? Do you include a pcm reflash or tune for this set up? I notice a custom tune comes with this set-up. I live in south Mississippi, US, and seeing that the climate is totally different from where you are, would your custom tune be efficient for me? Also, if I buy this set up, would you throw in the ngk spark plugs and the shorter belt for additional cost? I have a few more questions, but I have to leave for work now... Thanks for your time RAW

 

The pulley fits the gm hub and a tune is included but if you want a larger idler(we dont offer the belt anymore) and plugs you would be better off just getting our stage 1.
