Multi Question/Automatic Cobra Killer customers and Mail order Cobra Killer kit custo

Alright I've been savin' for the Cobra Killer kit for my 03 GT Auto, I just wanted to know if any other automatic cobra killer kit owners experienced any weird shifting problems that are sometimes associated with auto chip blower cars like not downshifting or anything strange? And for any mail order Cobra Killer kit customers who got the tune through the mail any drivability problems from the tune sent to you, was it right the first time and how has it been working for you? I know Tim is a stand up guy from when I've talked to him and garners much respect on this site I just wanna squash some concerns and get some feedback. Cause I'm not able to drive to Georgia to get a custom tune. Thanks for any help!
 
I can't help with the auto question. But as far as the mail order flash goes.. The driveability and everything was right on target the first shot. The only drivability problem that I have(which is common with blower cars) is a slight bucking at slow speeds when the rpm is around 1500-1800. But it is very slight and avoidable by just using a lower gear. But since my flash I think Tim has found the fix for the bucking issue.
