I believe low speed is 226. I can't remember what high speed is off the top of my head

I believe they were 226 and 236, but I'm not sure about the high one

Can that be adjusted when you get your PCM flashed? That's just too hot for my tastes..

On my old motor, I had set the low speed at 200, the high at 215..

Yes, it's all adjustable with any decent tuning software.
