I only plan on tuning this thing once. I planned my setup and am doing it all in the next couple months. I'm not going crazy with the setup since it is my DD so I'll just take my time, get it tuned right and probably sell the HPTuners after that to try and recoup some of the investment. I would definitely get the wideband if I was going to keep modding it or was going more extreme with it, but I don't see that happening.
