Sent it back - setting off trouble codes
I had one of these in my previous truck, a '97 F-150 4.6L, and it worked great. So, I bought one for my recently acquired 2006 Silverado 2500HD 6.0L. Unfortunately, the unit was sending faulty information to the vehicles PCM which caused the computer to think a lean condition existed. It would constantly cause the engine light to come on and it was always the same codes P0171 and P0174. I used my Hyperpac monitor to check the Fuel Trim and sure enough, the PCM had the Long Term Fuel trim pegged out at +25%.When I put the stock unit back in, the trouble codes went away and long term fuel trim returned to normal levels (positiive single digits).

Disappointed in quality
This is over priced garbage. The phone number given for manufacturer isn’t a good number. I had the same problem everyone else has it stops working and make your vehicle run horribly. I will never buy any of their products again.
