just curious... i have a first generation edge programmer (came with the truck)... on it it will display engine oil temp, transmission fluid temp, transmission main line pressure, and exhaust back pressure before turbo all while plugged in the OBDII port... in an honest opinion would any of these readings actually be accurate from the port... i would like to do the basic 3 gauges but don't want to get to in depth with them especially for the cost if can help it... thanks

 

just pull out your stock system get a tube and put a high flow filter on it and it will do the same thing just not look as cool or cost as much
