Default Edge EZ reviews

I am thinking about putting the edge EZ on my 2005 GMC extended cab 4X4. I am looking for a little extra power while pulling and a little extra fuel economy. I want something that will work with the stock truck. Please let me know how well it works, ease of use and ease to remove when taking the truck into the dealer.

Thanks

If you read the posts from 2002 to the present date you will find questions, such as my truck just quite or truck wont start etc. and the common reply through the years is remove the (hp increaser or the gas milage improver) module, Im sure they are all well designed and well supported by the factorys, BUT when you are along way from home towing who needs problems???? you need reliability and your Duramax is just that reliable, and powerful for your intended purpose.

good luck

drive safe

I have had my Edge EZ on for about 9 months now, and have probably put 15,000 miles on it during that time, a lot of it pulling my travel trailer. I have had no problems with it, although it stays in #1 (lowest setting) all of the time. I bought it primarily for a little extra power when towing. Installation takes about 5 minutes and the same to take it off if going to a dealer. I don't know if I have ever read on any forum of anyone having any trouble with the Edge EZ. I wouldn't hesitate for a minute to buy another one. If you plan on towing, I would strongly recommend a pyrometer (EGT gauge), as exhaust temps past 1300 degrees are possible if you aren't carefull. I can't vouch for any mileage increases, as I don't have a DIS, and I bought my truck to pull with regardless of mileage.

I have had the Edge EZ on my truck for almost 18 months. I have towed my 12k 5th wheel across Missouri, Kansas, and into the Rockies of Colorado with the power level set on level 1 and also level 2. I bought the EZ just for the enhanced power while towing and have been very pleased. With the EZ I have been able to tow up many inclines without downshifting from overdrive, which previously required a downshift. As Roy W said, however, you definitely do want to get a pyro gauge so you can monitor your EGT. Even though the EZ will enable me to pull some inclines without downshifting, I still do so sometimes in order to keep the EGT temps below 1300. Installing and removing the EZ is very easy and quick. I have had no problems with mine and would recommend it.

Thanks for the Advice, I ordered the ez along with a set of gauges from kennedy. Do you guys have pillar mounted gauges, that is what I ordered. Do you have any tips on the best places to plumb in the exhaust temp and the boost gauge? Also, can you change the levels on the fly? Is it just a matter of flipping the switch? Is the power difference that noticable? Are you guys running stock trucks otherwise?

Letgo, Was the edge ez that you were having issues with or another tunner?

Thanks

I think you made a good choice. I only have a pyrometer, but I mounted it in a black gauge cup, and stuck it on the dash next to the pillar with two-faced tape. The pyrometer probe is mounted at the rear of the passenger side exhaust manifold. Access for drilling the exhaust manifold is achieved by removing the inner fender panel. (Change your fuel filter while you're there).If you drill the hole with the motor running, no chips will enter the turbo, but wear safety glasses to keep them from blowing back into your eyes......Yes, you can change the settings on the fly by just flipping the switch, and Yes....you can tell the difference between settings. I've also added a 4" TTS cat back exhaust system. I didn't notice any change in performance, but egt's were lowered by 100-150 degrees when pulling my trailer.

I had a pyrometer and a boost gauge mounted on the A pillar. The probe for the EGT was mounted the same place as mentioned by Roy W. I am not sure where the boost gauge probe was mounted (I had a local diesel shop do the work). As Roy W said, you can change power levels on the fly by just flipping a switch. Since I did not plan on changing power levels frequently, I just left the switch under the hood. The only times I change the level is before I tow and after I tow. Otherwise I leave the power level unchanged. Consequently, I did not need to mount the switch inside the cab. Yes, you can definitely tell the difference in the power levels. Apart from the EZ, my truck is entirely stock in terms of the engine and exhaust. I have thought about modifying the exhaust in order to lower the EGTs while towing, but my local dealer said it would void my warranty. Don't know about that, but so far I just keep the EGTs under control by letting up on the throttle or downshifiting (or both) when necessary.

Will I get black smoke out the exhaust with the EZ? Will it mess with my catilitic converter?

thanks

Check my site under Tech Tips for gauge install notes.

You will get some smoke with the EZ. The Boost Stick will help clean that up and give you some power to go with it. Use level 2 as max when towing with the BS or you may limp the trans.

Do you recommend towing in level 3 with the EZ, How much additional power will I get with the addition of the boost stick? Will it help or hurt fuel economy?



Thanks
