what does tuna mean?

It's coon azz for "tuner"

Best bang for your buck for "hop ups" will be a set of reeds and reed stuffers from Chris Carson, also you can have Chris or James Perry (closer to you in TN) cut your heads. That will give you a little more compression and should improve your bottom end and midrange. Probably won't effect your top speed much. I don't know what tuner your motor has but unless it's a really crappy one you won't notice a difference with a change.

If you do go so far as to change the tuner you should really think about swapping to solid motor mounts since you'll be down that far anyway. Also you could ditch the liner in the can and drill the bottom of the leg for exhaust relief like the hi-po motors.

Setup will be where you get most of your speed from though!!!

I wish I knew 1 around here that done boats most say they wont put mods on due to the reliability issues, I am not looking to break any records or anything,just make it better, faster this guy is only 1 willing to do mods I have found so far.

You’re far better off working on it yourself, especially if you want to start hot rodding.
