What Years Fall Under LBZ Duramax?
You will be able to find 6.6L LBZ engines on GM Duramax models, and for this article, we will be focusing on tuners that are compatible with those engines (although many of the tuners on our list are also compatible with other engine types, so if you happen to be a truck aficionado, you are in the right place). GM only produced trucks with 6.6L LBZ Duramax engines from 2006 – 2007, so make sure your truck falls within those model years before tuner shopping.
What can a Tuner Do for Your 6.6L LBZ Duramax?
Tuners can shake up your old engine and revitalize your truck in a number of ways:
Trucks with 6.6L Duramax engines likely are not as hefty as they used to be. But using a tuner can be like rubbing the sleep from your truck’s tired old eyes – and then hitting it with a really hefty shot of espresso. Tuners will unlock your truck’s power reserves and turn it into the monster it has always been meant to be.
All this talk about heftier power may be making you nervous – tuners are already pretty expensive, and now you are going to have to get more gas to fuel your newly powerful truck? It is actually exactly the opposite – tuners will improve your truck’s power and its fuel efficiency. It sounds too good to be true, but trust us, buying a tuner can actually save you some money in the long run.
How to Choose an LBZ Duramax Tuner
So how do you know which tuner is right for you? Here are some key characteristics:
Let’s face it, dealing with anything automotive can be pretty dang intimidating. Add high-powered tuning technology to that mix, and it is easy to feel overwhelmed. Invest in a tuner that is simple and easy to use, so you will not spend more time figuring out how to program it than you will actually driving your truck.
The best tuners will go beyond enhanced power and improved fuel economy, and will just make your truck run all out better, period. Whether that means enhancing its shifting smoothness, or evening out the balance between truck speed and truck torque, invest in a tuner that will be able to do anything and everything for your truck.
Tuners are awesome for keeping track of all that is going on with your truck’s engine – and there are some great ones out there that can run diagnostic error codes to tell you exactly why that “check engine” light came on. If you are looking for data on what exactly your tuner is doing for you, choose one of these models.
