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
