Smarty is the best "box tuner" for our motors - EFI depends on who installs it and also how many tunes you would like- usually you get more bang for your buck with the 5 pack- I have stock, mild, mpg, towing, and max hp tune. You can usually buy 1-3-5 tuner pack.

For gauges you can do analog with several mount options (pillar, steering console, above mirror, and dash pods) the other option would be run edge CTS or CTS2 with one screen and ability to switch what you monitor. Usually has nice features like 1/4mile time 0-60 and turbo timer as well

I need some advice on gauges and how do I hook them up? I'm sorry I am new and I don't know how to do the gauges and all any help will be much appreciated
