Definetly best bang for you're buck!
Digital monitors are bling
for the App-Happy who know Much less than they should about this stuff
They're neither Fish nor Fowl. They try to do everything but end-up doing a poor job of it All.
They're poor gauges (relying on the PCM's sensors for the most part. If you add real sensors the cost skyrockets), they are Not as easy to read unless you dedicate the entire display to just one gauge (dividing-up the screen makes them too small). They may give you a warm & fuzzy because you can monitor so many things but, they're mostly unimportant like pulse width, vacuum, and the like. GET REAL GAUGES AND SENSORS IF YOU WANT ACCURATE & MEANINGFUL READINGS!!!
They're a poor scanner with limited diagnostic capabilities and again, give you a feeling of false security in your diagnostic abilities. GET A REAL SCANNER TO HELP YOU DIAGNOSE YOUR TRUCK!!!
They, for the most part, contain poor "canned" programming/tuning. GET REAL TUNING FOR SAFE & PROPER PERFORMANCE OF YOUR ENGINE / TRANSMISSION!!!
There is NO FREE LUNCH, you save Very little with something like the EDGE once you add Pyro & Trans sensors. REAL Gauges-Tuning-AutoEnginuity is gonna run around $1,000. Buy it as you can afford it, the difference will be the best money you spend in the end because you'll have what you should have to do the job right
