In a power box quandary

[rfcom]

Help - I can't decide which box to buy, van Aaken or Edge EZ. Engine is stock and I already have gauges. The VA has a boost fooler but no elbow for the turbo - it has to be purchased seperately. Both have about the same power/torque increase. The Edge claims a mileage increase while the VA does not. I need a box for towing and this will be the only power enhancement. I've heard good and bad things about both boxes. Some of the bad things are increased "rattling" noise, rough idle, failure rates. The good things are . . well. . power. Will either box have any adverse effects on my VP44? Opinions and comments welcomed. Thanks.

Your newer truck probaby has a "warranty void" sticker where the VA would hook up. I don't know if VA is sending new stickers or not?? That would be something to consider.



I have had one of every product edge has made for the 2nd gen trucks and all of them have been fantastic. You know what my choice would be.



As for the safety of your VP44, yes. In what I have read and my personal experinece the EZ and VA are safe for your VP44. How ever both of them in theory void the factory warranty.

The Edge EZ is fine with stock injectors, but I think the timing is overaggressive (i. e. , too much advance) for bigger injectors, especially on the higher-compression ETH (HO) engine. My truck is pretty "rattley" at idle with the DD2's!



Diesel Dynamics has their own version of the EZ (made by Edge but with DD-specific programming) that's optimized for larger injectors. If you're thinking about upgrading injectors down the road (and you most likely will ), I'd give strong consideration to the Diesel Dynamics TTPM (TrueTorque Power Module) rather than the Edge EZ.



Before the flaming starts, please note that I'm not knocking the EZ - I have one! I'm just saying that, if I had it to do over, I probably would have bought the TTPM.

I have to say Rusty that I could find NO fault with the way your truck runs or sounds... .



With that said, I would take yet another route and get the Edge Comp. I have it and really like it. It functions just like an EZ unless you pierce your pump wire. Also, on my '01 it does not interfere with any "void" stickers.



As far as idle quality and such, no problems in 40K miles here.



HTH.

Ditto here. Same combo, same situation, same feelings...

Would you choose the TTPM over Edge with stock injectors or only if you have larger ones? Their HP/Torque increase is less than Edge. Also, if you look at the dyno chart on the DD website, it shows peak torque at nearly 100 MPH Shouldn't the horizontal axis be engine RPM?

Please note my comment, "If you're thinking about upgrading injectors down the road (and you most likely will ), I'd give strong consideration to the Diesel Dynamics TTPM (TrueTorque Power Module) rather than the Edge EZ. " Only you can answer the first part - will you consider larger injectors down the road? If you will, I'd go with the DD TTPM - you might give up a little with stock injectors, but you'll be happier when you upgrade the injectors later.

Also, if you look at the dyno chart on the DD website, it shows peak torque at nearly 100 MPH Shouldn't the horizontal axis be engine RPM?

This is pretty common when a particular dyno doesn't have an RPM pickup for the engine. In that case, they use drum (road) speed for the horizontal axis.

rfcom,



On your 2002, if it is the stock HY turbo, you cannot use the boost elbow, you'll need to either use a J-hook, turnbuckle, wire or something along those lines to disable the wastegate on your turbo. This is what you'll have to do with either box.





Take care,



Casey

 

[RustyJC]

He said he has the 5-speed, so he should have an HX35-W, right? If so, the boost elbow should work fine.



Rusty

 

[Casey Ray]

Missed the 5 speed, my fault.

Spend a little more and get the UFM. No one says you need to pierce the pump wire. Just think of the UFM as a "in the cab adjustable EZ". As you can see, I too like the less agressive timing of the Diesel Dynamics boxes.

 

[outlawram]

what about superchips micro tuner. it has been brought up before. they claim 70hp. and it adjusts different tire sizes for spedp calibration. and also different gears. with three settings.

 

[Hohn]

I personally wouldn't use the Superchips. It was much-ballyhooed and did not deliver when dynoed.



IIRC, it dynoed more like 40hp.



On the Edge boxes vs. DD-- I would even go so far as to say that the DD box is better even with stock injectors. The less aggressive timing and lack of a HUGE low end spike makes the box much easier on the drivetrain, and easier to drive as well. When you add an EZ, the throttle gets a little "touchy" (i. e. less pedal movement needed for a given amount of fuel) and you almost have to re-learn how to shift.

I have installed an in cab on/off switch and settings switch for my EZ. I have been running it off most of the time trying to regain some mileage (if the EZ is indeed the problem - I kind of doubt it). About once a week I kick it back on and I have been having no problem with the shifting between the off and on positions, other than I have to shift a little sooner (time wise).



The control is all in the right foot. I roll into the throttle as I accelerate trying to stay about 5 or 10% ahead of the engine, rather than mash it to a certain spot and wait for the engine to catch up - speed or RPM - to hit the shift point.



Timing, yeah the EZ is aggressive. IMO go with the Comp and leave the pump wire off until you are ready to play with the big checkbook. They both just plug into the can bus and the MAP sensor. Easily removed if a trip to the stea... dealer is needed.



NOTE: I am in no way suggesting that you should defraud the stea... dealer, it is just that I see no reason for them to note in your record that you have engine/fueling modifications if you are going in for un-related warranty or recall work, like a squeaky door hinge or something like that.

Thanks for the comments. I ended up ordering the DD TTPM even though I may never upgrade injectors. As many others have said- this site rocks . Glad I renewed.

Anyone have an opinion on a TTPM and RV275 combo? Will the stock clutch be OK? Even tho the box is optimized for DD injectors, I can't imagine it knowing the difference. My main goal is hauling the TT.



Jim

 

[Sticks]

Your clutch is a crap shoot. It may hold, it may not. Some people have run stage 3 injectors and an Edge comp for almost a year - and not being gentle with it - on a stock clutch. Others started slipping with just an Edge EZ. Personally I would spend the money and get the Stage 1 or 2 injectors and not waste the money on the 275's. Sooooo many people have started out with the 275's and ended up going larger with in 6 months, I hate to see another waste the money on that little venture.

At one of our bomb partys last year someone put a EZ and 275's slipped the clutch in less than 10mins

275's and clutch

I have been tweaking Dodge's for a long time. The 6speed clutch 2001-2002 is usually not going to hold with any fueling box injector combo even 275's and EZ. The stock 5speed clutch usually will hold with 275's and EZ, but not always. If you are building the truck for towing I would suggest the 275's, over any of the extrude honed injectors. I still have a set of 275's and I run them quite a bit, I like the smoke control and good mpg's.

EZ and DD2s-- stock clutch still going strong here..... ~350rwhp
