i got my 4.10's in ( car does not seem that much faster ) dont ask why, idk if the guy put em in right or not but i havent heard any whine. I mean i can tell a slight difference, there must be something else wrong possibly my tranny. Anyway thats beside the point, i was having my godbrother install my speed cal today and the connector from the tranny is completely different then the one from the speed cal. I have a 96 GT Auto. Anyone know the deal and how i can get this speed cal in? My speedometer being off is really pissin me off and on top of that i just got a speeding ticket the other day because i had no idea how fast i was really going. SOMEONE HELP
