Yea it comes in the 900 rpm kit....shoot me a pm if you are interested.
If you have a solid electrical system you should be ok, but I was also having some other issues (and still am) like there is a amp draw on my battery when the car sits and wont start after a day of sitting without being started.

If you end up doing a before and after dyno with this then I would love to see how it turns out......later.
