Re: Just got hummer what are the first mods that are a Must?
Do not get a Volant, they rob your motor of HP not add. I owned a Silverado SS that had a Radix and a bunch of other goodies, a friend owns a dyno so we tested the **** out of it. When the Volant was bolted up I lost around 7 hp, with the standard K&N drop in I gained 5 hp. For the money its a no brainer
