I have a DHP tuner i have been playing with to try to get it tuned, i am def going to pick up a wide-band here in a few days. I have a 4.2 stroker motor that i am going to put in my other car (one of these days), so i need a wide band that will support both motors. I guess the one ZZP has isn't compatible with the 4.2? So what would i wanna get for a wide-band???
