Correcting speedo after gear change Ive been out of the f-body stuff for a while now, but now starting to get back in it. On my 97 z, when I put the 4.10 in it about the only thing to correct the speedometer was a hypertech power programmer. They were a little costly, just wondering what is the best way to correct it now, or if the power programmer is still about the best choice. Thanks
Get a computer tune LIKE PCMforless.com or something like that.
I also had a black box come with my gear set from slp. With this you can put in your gear ratio youself. (it stays hard wired to your car) I think they might sell them at slp. I would serously get a comp tune like mentioned above.
Do it quick or your going to lose mileage to your motor like me, since your computer thinks that you have stock gears in the back.

www.madz28.com It's a cheap mail order tune and he'll correct for gears. That way you correct the speedo and pick up a little more power.
