Has anyone used one of the Hardline Tachs? I installed on in my 94 GTX and even thought the hour part seems to be working, the tach part is not. It shows me idling at 2500 when I know I'm around 1500, and then it shows around 2100 at full throttle.
Another question, what is the normal mph on the 93 and 94 GTXs. The 94's speedo shows around 45 full throttle in glass water, but the 93 shows 35 mph and neck to neck it is slightly faster than the 94.
