Don't get me wrong. I want a tune for this truck, but at the moment money is tight. I don't plan on getting a tune for a little (2-3 months).

 

Why not just save and do everything at once then?

 

I got my ARH LT's installed a week ago (which defintely made some power!) and for about a week I drove it without a tune, now with a tune...it's night and day. Save up and get both as the above poster said, it's the way to go.
