Learning alot with this, will try that high speed thing. That was my truck. I was attempting to read it to keep my buddy from driving over just for it to fail. Well in that case will have to call him up and try his truck. My truck is a dsp 5 tune.
Will keep you posted, thanks alot for all the assistance.
