I just had 3.73s put in and i've been trying to get ym predator tuner to change the gear ration so the speedo will read right. Ive installed the tune with the adjust gear ratio 4 times, and even unplugeed the battery for a few minutes after and im still running 10mph off. Anyone had similar problems or have any suggestions?

I have heard noyhing but problems 100% about the Predator tuners, and I heard there customer service is the worst, I know this sucks as a solution as you have paid big for it already, But invest in the SCT Xcal 2 Tuner.

wow....you have heard the wrong things then.

I have never had any problems with my predaor and my gear change worked perfectly. I have used customer support including the forums 3-4 times and always got a answer very fast from them. My SCT works fine also......

are you sure you got the 3.73 and dont have the stock gears still in there or 410s instead

ok, if the speedo is still off, i would then
look at your wheel/tire diameter

Zero problems with my Predator.
Used it many times.
You'll have to change to 99% or lower.
