Oh man,sorry I haven't answered your post before now. I don't have anything as far as maps go. I'm trying to find some guys that have had tuning done. I'll let you know if I find anything. http://www.bluetraxx.com/reviews/kds_throttlebody.htm . These are very conservative gains on this dyno test. I think you will see at least this much.
I'd be very interested in doing this if we had more support for the map changes. Even if we could just find out where in the rpm range we could make changes to compensate for the additional air flow. Any information would be very helpful.
I just installed one of these in my 869 and absolutely LOVE it. This cam replaced my x-2 cam and I couldn't be happier with the difference between the 2 cams. Great Job on the Cam Kenny and keep up the great work.
