Its been a while since I've posted. Been buried in my other hobby. Anyways I have been getting back to my truck. I lost my tranny about 8 days ago. Fortunately I have already bought all the parts to rebuild and a torque converter. I had a friend do it and its all done. I went with a TB converter. At around 40 to 50 mph the converter wants to lock and unlock. I'm guessing a tune would solve that. I was looking into Diablew tunes. I like to have the ability to change tunes at will. Like going from a 87 octane to a 93 or e85 at will. This truck is my daily. I know a lot of people will say send the ecu out or get a hp tune. I don't want to be stuck with one. Any suggestions?
