It certainly does appear that Route 66 is done doing the TnT sessions for the remainder of the year... you are, in fact, correct sir.
I've never run my car at Byron or Joliet... the furthest I've ventured from home is Gateway. I frequent Cordova and consider it as 'home track' even though it's 104 miles away from my driveway... been to Havana too, but that place is a HOLE!
Good Luck and have fun @ Byron... enjoy the cool air.
aaaannd... Weeeeee!!
I'll be tuning for some 10.teens next time out... as much as I want a 9 sec. timeslip, I don't want a split block

and putting more nitrous to that stock block would be a sure way to do it!
L8R!
