no i havnt.....

 

i would definitly go to a dyno when you get the chance. something doesn't seem right about your time or mph on a 150 shot. actually, i would have a mechanic take a look at your car and make sure you don't have any internal damage before you head to the dyno. thats what i would do if i was runnin a 13 @ 104mph with a 150 shot.
