Hi Monty
Going on what you said i got a 9901 with 41021 today for my p5 and put in the 8mm and all i can say is wow really brought it to life
one question on the tune though it seems great high speed and good smoke and low end is also great however mid range it isnt making the power it does at very bottom and very top its not to lean or rich on the top or bottom it doesnt hesitate or bog or anything like that it just drops power slightly should i play with the mid range needle its still factory as i have not touched this one any advice will be great
Thanks Ben

try a 7.5 and see if it helps any

Hi Monty
I just purchase the plus 4 and was going to do the heat cycle breakin, I was wanting to know once I get the motor preheated to 180 and the motor temp declines during the initial run in do I lean out the HSN and LSN a little at a time until I can get it stay around the 190-200 degrees? My next question is I plan on using the oddonnel plugs and run the byrons 30% Pro fuel and was curious on what plugs to use on the standard or turbo. I will be running JP4 for the time being.

Monty;
I have the ToroNero turbo and a 9853 w/41005(short) on it. This really launches my X2 compared to what i was using before.
I am looking to get another pipe. Question is... what should i expect from a 9901 and 9886?
Thanks!
