So for the 6 years I've had this truck I assumed that all 2006 Silverados with the Duramax had the LBZ engine.... I also assumed that since mine wouldn't "light the tires up" was because it was a dually. Just learned I could tell by the serial number what motor it had and came to learn I had the LLY. I also learned the 2006 LLY had the improvements of the LBZ mechanically but NOT the ECM that gave it the additional HP and torque. It's a great truck and has been very reliable. I could use a little more power but it's actually ok as it is for my use of primarily pulling a 21' center console boat.
However, I would like more MPG and I've heard the LBZ was a couple of MPG better when driven responsibly. I've done enough research to find that tuning one or even getting info on tuning one isn't as simple as I'd assume it to be. *Too many salesman and not enough actual facts.
My 1st question is basically: Is there a reliable off the shelf, plug and play tuner that will give me more MPG, HP and torque without going to a shop and forking out $$$?
Second question is: Has anyone out there tuned their '06 LLY and what is their advice to doing it (or not doing it)?
Final question is can I expect better MPG and power from a tune or is tuning really all about additional HP/torque vs economy?
Thanks in advance
