Hello,
I have a 98.5 3500 4x4 5 speed with a reman injection pump and new transfer pump. If I installed an EZ for towing purposes, mainly so that I could stay in 5th gear above 1600 rpm on the interstate, would my EGT's stay below 1250? The truck is otherwise stock. Is this box likely to throw codes or cause any other problems with the truck? I have read many posts about the box itself failing, and would you recommend for or against buying a used one? Would this be a trouble free addition? My truck will pull anything up any hill in 4th, but with 3:55's I have to shift down a lot. The truck has 141000 miles.
Thank you

 

mine is great i do not want to drive without it. 1 year no problems this edge is like night - day when towing. never seen temps over 1100.

 

I don't recall reading of that many failures with the EZ, however on the ones I remember, Edge is very good about standing behind their products. I bought one used and it's been on the truck for a year now. I believe that makes it over two years old counting the time that it was on the previous truck. It really added the little extra giddy-up-go for towing our 5er. The truck stays in OD now without having to drop a gear on the minor hills. I would highly recomend the EZ to anyone who is looking for a mild increase in power without taxing the VP44. I've never had it set any codes or cause any problems. It has been a great addition in my opinion. Here are the dyno numbers for my truck.
Stock
198.8 HP ,,,,,,,,,,,,, 385.4 TQ

After adding the EZ
227.3 HP ,,,,,,,,,,,, 506.4 TQ

 

The Edge EZ alone will raise EGT's significantly. If you install the boost elbow on the turbo (or other turbo mods to increase boost) EGT's will stay in line. Improved intake and exhaust will help a little with EGT's but nowhere near as much as the turbo mods.

 

The EZ shouldn't throw any codes or cause any problems with your truck. You'll notice more engine noise from the timing advance but it's a diesel... You'll definitely want to install the boost elbow. A free-flowing exhaust and at least a BHAF will keep your EGT's well below 1250.

Dyno numbers (11/27/2004)

These are just the type of replies I am looking for. I would probably put it on the least agressive jumper setting to limit smoke. Would that help control egt's? Also, how much boost will I get with the EZ w/and w/out boost elbow, and will that hurt the turbo, or blow off intercooler boots? Right now stock I am pinning the boost gauge at 20 psi at 2200 rpm+ towing, and I thought they weren't supposed to go past 18.7 or something like that. Thanks again

 

I dont have gages, but the E/Z's for 98.5 and 99 are same, and boost elbow came with mine, tood box off for a few days and set over boost codes. I dont have gages but i think the code is set at 23 pounds. with the box on i feel it builds more boost, I would think 27-32 with the box and elbow.

 

With the EZ and no elbow, you will continue to see your current boost numbers. With the elbow, I can hit 32 psi in 5th and 6th. I'm not sure about the older trucks but you should definitely see in the mid to upper 20's which probably means a new gauge for you. I'd recommend a 60psi gauge cause you never know where you're gonna toss on a KSB1..

I would think you would see some lower temps(comparatively) with the EZ on jumper setting 1 as long as you weren't seeing boost numbers over 20 psi.

 

ok i had an EZ on my truck for close to a year, then my clutch started to go south, so i took it off. My clutch started goin while on an elk hunt, and i had to pull out TT back home. The hottest my egts have ever been was when i was pulling our trailer back home from the hunt, WITHOUT the EZ and boost elbow, i went back to the stock elbow cause i didnt want my truck setting the overboost code, and defuling like they do if they see to much boost. So in reality the EZ LOWERED my EGTs cause it was allowing me to push 10 PSI more boost. I wish i could afford a clutch, so i could put it back on Oh BTW i dont think it was the EZ that toasted my clutch, i think it was the roads i was on while hunting, i had to slip the clutch quite a bit to get where i was goin

 

I have had the Edge-EZ for just over a year now and love it. I awoke the engine first with some rv275's and raised a monster when I added the Edge-EZ. This is my current power level and I just turned over 135,000 miles today with the original VP44 still. In my instruction book from Edge it states that the boost elbow with the Edge-EZ with produce 28psi of boost. The stock boost is set at 21psi. I did have the problem of blowing of the intercooler boots though. Took out the elbow and have the stock elbow in right now. Other than that, it's a great product and great company to deal with if you should have a problem.

 

I don't know about that edge unit but I can tell you that my box from D/D is hands down the best thig I ever did for my truck.

somthing else to look at also. i have a blue chip box that goes from o to 135 horse and can be adjusted with a dial in the cab...wow what a box

 

Pike--

The EZ is a good mild upgrade that's easy on the VP44. Jumper settings affect pedal response and how the engine reacts to boost. On the most aggressive setting, the pedal will give you 66% of maximum fueling available, and you only have to wait for 3 psi of boost to get the other 33% back.

On the mildest setting, it's opposite: 33% with the pedal, and you have to see 20psi before you get the other 66% back.

On the middle setting, it's 50%/50% and 10psi.

The main problem imho with the most aggressive setting is that it makes the pedal feel like an on/off switch and brings the fuel in so fast that it kills that last inch or so of pedal. IOW, if you floor it, you expect more as the pedal goes down, but the EZ finishes early, so it's a little disappointing. The most aggressive setting also makes the cruise control more aggressive and less smooth--not to mention being harder on the clutch.

The stock clutch should hold an EZ on all years. Mine is holding the EZ *and* 75hp injectors. Dynoed 390/918 on stock clutch.

HO trucks have too much timing in concert with the EZ, so I'd recommend the DD version if you are yanking something near max GVWR.

I have had my EZ for 2 1/2 years now with "0" problems. Towing my 12K Fiver I could not pull a decent 6% grade in OD. I was usually in 3rd gear and feathering the accelerator to keep EGT's under 1200 degrees, boost at 28 PSI.
I never had a problem with smoke with just my EZ
I just switched to a HX35 w 12cm wastegated turbo and added DonM's 1.5 injectors. I am hoping that this towing combo will help me maintain the speed limit on long steep grades as well as keep my EGT's around 1200... I am very pleased so far with the non towing performance! Just gotta hook up the fiver and give it a real test.

Where can you get a different boost elbow such as you guys mentioned?
