Pillar question
And to answer your question, either way you go you want an electric pressure gauge. As far as wideband goes, I had a Dynotune Wideband and guage in the car and it worked perfect. I know they make quality products cheap.
For the wideband i know dynotune has a nice one. Innovative is another nice one on the market. Trick Performance has recently came out with a wideband setup and we have had good results with that item. We offer several different wideband choices http://www.nitrousoutlet.com/catalog...del=87&dept=11
