1 will i get reciept of stategy before & after tune?
2 does the mpg differ drasticly between the 40hp heavy tow& 65hp moderate tow

I can't answer most of your questions, but I might help a little. If you know that something is wrong with your motor, or it needs to be cleaned, then do it before you get any custom tunes.
And also welcome to the forum!
