i just got back from las vegas... i really had a chance to open her up..and owe boy...there is a highway just north of vegas called the 93..myself and freind took it up there and WOW...i had taken the box up there before and i got it up 157. i ran out of space and courage to go any faster..this time i got the 997 to 165 ...the big differnce for me was in the box it felt like i was going really fast,with all the good and bad that goes along with that feeling.in the 997 it felt like i was going alot slower than in the box but was at 165...its kind of weird in a good way..i really love my new cab...thanks again to all
