Wideband
I have been searching for info on whether a wideband is something that is a must to have, or if it is just for you pros. From what I have gathered it really increases/betters the data you can gather. All I plan on doing is tuning for the cam swap, and little things like injectors, gears, and such.
Now the PCM does have a basic tune on it from a shop tuner, does that cause a problem?
Sorry for all the questions, but I figured I might as well ask people that are in the know.
Thanks
