Hypertech Stage III
I just bought the hypertech to convert my speedo as I changed the rear end ratio. For you guys that may have done this, is there anything I should watch out for? Thanks.

Are you using it on a 94/96 C4? Just make sure that your battery is up. Otherwise you can corrupt the memory of the PCM, and that would require replacement or repair of the PCM.
