Lots of smoke! I just wanted to relay the difference between my 600 and Big Bob's 555. I was at 4K plus miles and BB at 7K plus I believe. I had on my camper and Bob his duallies. Both 48re's. Bob bought his last fall and mine purchased in Feb with Jan 9 build date. I was first on dyno and Bob #35. We both hit 250hp (less than a horse difference). Bob had is AFE and smooth intake elbows and new 51" muffler. Christian, the dyno man says he sees 10 to 15 horsies difference tween the two, usually. There you have it. George
PS... really something to see Jason from Piers with his black 93 he bought new and new motor turning 538 (or something near that through all the black smoke!). Saw an early 90's Chev with a Cummins hit 500...
