'm sure you will get a lot of responses pro's and con's..... However, I have had better luck with EDGE w/attitude. With the EDGE you don't need gauges, safe to run on stock truck, adjustable fuel on the fly, alarms, safe defueling settings, many options on monitoring, egt's, boost, tire calibration, air intake, etc. , etc, and can be upgrade to "hot " setting. Bullydog has some simular stuff, except it is a downloader and has had some problems screwing with your ECM... . EDGE is not a downloader, and IMHO is safer to run...
