Sorry about the long post guys - I'm hoping someone has been through this and can point me in the right direction. I posted this question already once, but I guess I didn't make any sense. I just bought a 97 Cobra that has been converted with a T-56 6-speed. The car has a 4.30 gear, or so I was told The car runs almost 3k rpms @ 70 on the highway in 6th, so that sounds legit. The speedo isn't hooked up - the guy told me he needed a part that was on backorder (???) - thought he was talking about a new VSS. Turns out the VSS was unplugged - I plugged it in & the speedo works - however it's waaayy off. At about 20mph it reads about 140. What I need to know is if I can correct the speedo calibration with a handheld tuner (which I'm planning on getting anyway) or do I need something like the SpeedCal? If I use a tuner, which one works for a 97 Cobra? I was leaning toward a Predator 2, but I don't see any listed for a 97. Is there anything else I need? Any info is appreciated. Thanx
