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!
