does the comp make the truck more responsive? i'd just like engine to be a little more responsive. i rarely rev past 2k so it won't be that bad for the transmission right?

 

Sounds like you want the EZ instead. Bout 60 extra hp and shouldn't harm your tranny. Especially if you drive it like a grandma. The comp is way more aggresive. It can add up to 120 extra hp and WILL damage your tranny. The EZ is a nice kick in the pants. It will definately wake the truck up around town. I love my Comp though. If you absolutely, positively, 100% sure, not a doubt in your mind that you only want a little extra power, get the EZ. But, if there is the slightest doubt that you may want to upgrade later on down the road, then get the Comp and leave the pump wire unhooked. It will act just like an EZ. Until you hook up the wire. Plus you can adjust it in cab. Most people end up selling their EZ and upgrading to a Comp anyways. The power is VERY, VERY addicting. ;D

 

although i dont have one (yet), everything ive learned about the edge products are that the comp will make an enormous difference in engine performance. so much so as to push the stock automatic tranny beyond its limits. u might be better off with the EZ or a comp w/o the pump wire if u just want a little more performance and a dependable tranny

 

we have an edge comp a PE 4200 and we still have the stock tranny NO upgrades to tranny. different huh. gonna send comp next week and get the Drag version installed.

 

what are the stages to upgrading the tranny? Would a valvebody tide over the trans with the comp? or do i need more...like a new tc and so on?

 

You will want to do the Torque converter first. It is by far the weakest link in the stock autos, as well as the biggest source of heat. The VB is nice AFTER the TC, but by itself is a waste. You need that TC a lot more. And hey, it's only about $1500!!

I bought the EZ and not the comp. It is very wise what you were told about getting the comp if you have any doubt. *I* had no major bombing aspirations- 350rwhp is enough for the next few years or so, and I don't have to run intake or exhaust mods either.

Also, keep in mind that putting on a Comp does NOT meana automatically that your trans will explode. It mostly depends on how much discipline you have in how you set it and how you operate the pedals. With these, you could keep the stocker alive for a long time.

It's not how much power you have, it's how much you USE.

That said, almost all of us are weak and will use what we have.

While there *are* stages to trans upgrades, you will be happiest by just biting the bullet and getting the whole thing done. ALso, the increased performance from just the trans upgrade may lead you to decide that you don't need as much in the power upgrades.

Take this is you see fit from me, an Edge EZ owner: if I were looking for a fueling box, it would be the TST Powermax. It's generally more reliable, it's the cheapest max fueling box, and can be programmed any way you want, from standard levels to VP44-eating levels.
If you prefer the Edge style box, get the Diesel Dynamics version. Their version has better parameters, is less smokey, and a little easier on the engine since it has less ignition advance.

My dream combo would be EDM 4s, a TST pmax competition model, twin turbos, and all the other mods needed to run that. But now you are WAY past the point of diminishing returns.....

For now (and the foreseeable future), and I am happy with just DD2 injectors and my EZ.

It's also a little easier on things to make power with injectors over a wire-tap box; less heat, less strain on VP44, and much smoother (more driveable) power delivery.

I highly recommend the edge comp even if you don't think you will use all of it at first. use it in EZ mode for a while -- you can always hook up the pump wire later. But the benefit of using the comp in EZ mode is two fold:<br><br>1. the box rides in air conditioned comfort. I don't care what they say, heat is an enemy of electronics and no matter how long things will last under the hood, they will last longer in the cab.<br><br>2. you get really cool control over low boost fueling, with adjustment control at your fingertips. more control than changing the EZ jumpers. I run mine on level 1/3 most of the time (level 1 is all you get without hooking up the pump wire). <br><br>that said, if you're a &quot;set it and forget it&quot; guy, then the EZ is best for you. I'm just a tweeker and can't stand not having control over things to experiment ;D

 

Go with the Comp and use it like the EZ, it will save you money down the road because you will be upgradeing later if you don't.

 

will the comp in EZ mode smoke more than the regular EZ? I'm just in it for the smoke not really the VP-444 fire breather.<br>DM01 ;D

 

I don't think so. If you want smoke put the comp in 5x5 and powerbrake it whooooa doggieeeeee. 8) 8)

The only thing worse than heat for electronics is repeated warm up and thaw cycles, and up here in Canuckville, we've had alot of trouble with the Comp LED's failing during winter use. In deep winter, we can see as much as 120F of temperature swing, with rapid cooling after the truck has been shut off. Edge has apparently changed some of the components, so I guess we'll see next winter if the change has been a success. The EZ, on the other hand, has been virtually trouble free, with a warranty return rate of less than 1% (our experience).<br><br>Rod

During the winter up here, we reach down to -40F and the cabin of the truck can be 70F or 80F. When the truck is shut down, cooling back to -40 can occur pretty rapidly, within a few hours. Warmup is even quicker, with the cabin warming from -40 to +70 in minutes.<br><br>Rod
