Me an my friend are going out tonight to break-in his new Nelson Tune. But I have herd that it takes it a while till all the new setting are loaded into the system. So my question is, How long till he will notice the full effects from the Nelson Tune?

I noticed difference first drive I took. Then the little things that it didnt do before I started to notice. And oh yea pegging 120 MPH is always fun :anitoof:

When I put mine in I noticed power right away, but the more I drove it the power just kept getting better.When I finally drove a long distance I had picked up 2 mpg.That is awesome to get power and gas milage.Nelson`s tunes rule!!!!!!!!!!!!
