Just spoke w/him at length. He recommended getting two stock secondary 850cc injectors and installing them in place of the existing 550cc primaries. So basically, run 850cc all around. He claimed this was good for ~400 wheel hp, which is good enough for me.

Re: the Power FC, he also stated that at 90% inj duty you're about as far as you want to go. That's fine on a regular basis, but no more than that. I have a friend seeing 98%, so he definitely needs to turn it down.

Hope you guys found this interesting...
