I've been lookin for a tuner for a long time and cant seem to find one.. the LT1's have tunercat and LT1edit but us v6 guys seem to get shafter... I just want a tuner that can get rid of rev-limiter and raise my top speed limiter.... anyone know of anything to do this?
thanks

 

I know there are some people out there that tune the V6 cars, but they are very few and far between. It's also very expensive, simply because there is not much of a demand for this. Also, for the 3.8 Series II, being OBD2, it is VERY difficult to both decode and have a cable that translates the ALDL port transfer information to something the RS232 port can read. About the only thing I can think of is a Tech2 tool for the 3.8 Series II, which can do what you are talking about. However, it is also very expensive, not something you'd want to buy and use once just to raise a couple of limiters.
