Can someone correct my speedo for me after my gear swap?

[rbaksi]

I'm swapping a 3.42 rear in replacing a 2.73 rear and need the speedo to be corrected.

Can someone that lives nearby change this for me? I dont have tuning software or a Hypertech. I do have a tuning cable however. I'm in Bridgewater.

I dont want to spend the money on a tune just to change gear ratios.

unfortunately you will need to get a tune to change it. HPTuners doesnt work with LT1s, talk to Josh from JSPerformance

Check out older LT1 sites, some of em have .bin files for stuff like that. If you download a program like LT1edit etc you can do the tweaks yourself.

Be careful with those. I've downloaded some of them and didn't contain what they said they contained. If the OP does download any .bins, I HIGHLY recommend opening them up and checking the tables.

I see theres a 30 day free trial to c.a.t.s. Tuner. Will that work? I have C.a.t.s. Winflash also
