I haven't messed with mine (bomb wise) since the last roll on the big drum. It's fun and a damn great daily driver, I did mention its fun - right?
I figure this, if I go to 600+ HP - why? what's that going to gain me? 75 more hp and a quicker ride to work - not.
I'm liking mine where it is and appreciate that its sooo drivable, and only takes 1 second to hit the switch from 1/1 to 5/5 and then it's "away we goooo" time.
