Well Virgil was a good enough dude to hook his laptop up to my truck (he has HP Tuners) and we drove around for awhile to see if there were any problems. Turns out, the O2 sensors are barely registering and HP Tuners is giving an error message. This is all dumbspeak - I'm not sure of the exact terms, but anyway, something is wrong. Virg is gonna email me the file and I'll send it to Allen and hopefully he (or anyone else) can give me some advice.
