I weigh 270 lbs; built like a "World's Strongest Man." So the suspension in stock form is quite alright.
I put on a seat concepts seat - huge improvement. Also added an airhawk.
I haven't done a tuner yet but I don't know what it would give me since I have already done the PU mod with a muffler. Please educate me why I should get a tuner for the 610. Will it give me more power?
