The Saga continues. Now Im having a problem with O2 sensors.... changed out all 4.. ended up changing them again after a month. Needed to put a defouler on the down stream O2's because of the Highflow Cats. Made sense seeing that the truck originally had four. now running only two (Highflow at that). So now the truck runs a lil rich. but not the problems like before. just did the job so we'll see what happens. Any advice in the meantime?

Have you considered a EB? LOL Tuner written for you, can make it off road and eliminate the need for O2's if you want.

I Have. I just looked into the Diablo programmer. Whats your thoughts on that Papa Tiger?

It would seem Diablo or Livernois as being at the head of the class now. I know Livernois is the fastest EB in the country right now.
