Hypertech Max Energy Review

July 22, 2008

A while back I posted about finally having a chance to try out the Hypertech Max Energy on my 2005 Dodge Cummins.  It had been my habit up until then to try a new diesel performance chip or module every couple of weeks just to be able to offer reviews to you our readers but I must admit that I have enjoyed having the Max Energy on my truck so much that I haven’t had any motivation to take it off and try something else.  I want to start this post off by listing off the pro’s and con’s that I have found with the Hypertech Max Energy tuner:

Pros:

  • Excellent Power Increase – Now although I have not had a chance to dyno my truck with the Max Energy tuner Hypertech does claim an increase of up to 176 hp on the cummins.
  • Tow Safe – One of the best parts about the max energy is the fact that even on the highest power setting (Stage 3) you can tow safely. Now I haven’t had a chance to tow my toy hauler with this module I have towed several loads in my heavy duty dump trailer and have yet to see tempratures raise to an unsafe level.
  • No Smoke – Now I know for some of you that might sound more like a con than a pro but personally because of local authorities I’d rather fly under the radar as much as possible and one thing that helps with that is avoiding the smoke out of the tailpipe.  Also, another interesting thing to note about the lack of smoke, when I had the Diablo Predator Diesel Tuner on my truck it smoked a ton more.  It also had a little more torque on the low end but the same power at freeway speeds.  So it seems to me that Hypertech has done a better job of bleeding every ounce of power out of every molecule of fuel rather than just going the route of dumping as much fuel as possible.
  • Internet Updateable –  You can always get the latest version for your vehicle.
  • Oversized Tire Calibrations – Got oversized tires?  This unit can help!

Cons:

  • Small Screen – As you can see in the picture the screen is clearly smaller than the Superchips Flashpaq Tuner screen.  This is sort of a pain when working with it but makes for a smaller unit when you have to store it in the vehicle.

As you can see I don’t really have many con’s. I have been really pleased with the hypertech max energy, and if you are just looking for economy I would recommend checking out the Hypertech Max Energy E-Con.

Cummins Performance, the Best in the Biz

July 1, 2008

The Dodge Cummins diesel is known for its diesel fuel mileage and ability to be built up for power…. and known for its transmission for different reasons.  The Dodge Diesel trucks are the favorite of anyone that is looking for fuel economy in a diesel and doesn’t have a brand preference, because the dodge gets the best economy of them all.  Even at that, things are tight with the cost of diesel and the hard times in the economy.  There are some things that can be done to make it even more fuel efficient.

The first thing that anyone is going to do to make their Dodge Cummins diesel more efficient for fuel economy and power is install a Cummins diesel chip, programmer or module of some sort.  Cummins performance diesel chips, programmers, and modules all do essentially the same thing.  They alter “timing” or when the fuel is injected; “duration” or how long the injector is held open to release fuel; or “pressure” which slightly increases fuel line pressure to put more pressure up against the injector and get a better atomization of the fuel.  Most chips, programmers or modules use a combination of the methods to improve engine efficiency.  Most chips, programmers or modules give anywhere from 1 to 5 miles per gallon increase in fuel economy, dependant upon driving habits and the truck configuration itself.  The gains for the 5.9L Cummins engines are pretty consistent, however, the new 6.7L Cummins diesels are different.  They have a new emissions control system with a diesel particulate filter that hampers performance and fuel economy.  Most chips give these new trucks about 1 mpg better fuel economy.

Another way to increase efficiency and power are air intakes and larger diameter exhaust systems. Cummins diesel intakes generally give about 1 mpg and exhausts can be anywhere from 1 to 4 mpg.  If you do a chip, intake and exhaust all together, you actually get a little bit more out of each item.  The nice thing is that all the add-ons give more power and pay for themselves pretty quick in the added fuel savings.  The newer Dodge Cummins diesels don’t really need an exhaust upgrade since they come standard with a 4 inch diameter exhaust from the factory on the 2004.5 model and newer Dodge Cummins diesel trucks.  Performance diesel exhaust changes that can be made on the 6.7L trucks is very minimal due to all the sensors in that exhaust system.  It’s nice to know that we have alternatives though.
