How do un-install my Comp?

How would I go about un-installing my Comp? I didn't install it, so I don't know how it goes in. Any help would be great.

No comp no boost fooler. I run mine off 90% of the time, but the boost fooler is still running with the unit off. I do not have the VP wire tapped either. So far do not need it.

If the turbo waste gate has been modified with a turnbuckle(see you sig says Jhook), you will have to remove that also, or you will defuel. What boost are you seeing? SNOKING
 
Well I'm up around 27psi. I'm just not sure if I need that much power. I want to keep my truck as long as I can. And it just seems this BOMBin stuff is trial and error given the problems I hear about. And I don't want to kill my VP and run into the problems other guys are having from runnin big power. So I was thinking of just going with more mild to medium power. Like an EZ, Mach 1. 5 maybe 2s, an HTT turbo, and the DTT trans. I was thinking that a set up like that would be pretty good.

BDR - FWIW, you won't need a different turbo with only the EZ and 1. 5's or 2's. Anything bigger than stock will just be laggy and will hurt daily driving. You would likely run hotter around town with a bigger turbo with that setup. It's really just not enough fuel to justify one. See my signature - I've been down that same road and have decided that changing turbos with what I'm running is just a waste of money and effort.



A buddy is running Mach 3's and Diesel Dynamics' version of an EZ and is still running the stock turbo. His temps are fine and that setup doesn't really require a turbo swap either. Granted, you may gain 20hp or so on a dyno because you'll be in the higher RPM range but it's just a waste for daily driving.



I would leave the Comp box hooked up and just run it as a boost fooler like someone mentioned above. Then the power's always there if you need it and you'll probably eliminate the need to do any transmission work. ;)

Well I really want to get rid of my HY, I was thinkin maybe an HX35 or something. If I was playin around one day and decided to run the higher levels I would trash my transmission. Wouldn't my EGTs go up with the small turbo on the higher levels? It just kinda seems like it would be a waste to have the Comp with all these great levels of power and not use them.



Where did my sig go?

Just remove the VP tap wire and run the Comp as an EZ. Set it up for:]



1x1

2x2

3x3

4x4

5x5



It will now function like an EZ and you have the ability to turn it off and on inside the cab. Depending on the number of LEDs you have on (main level) you will be varying the sublevels. I run on 3x3 most of the time and poke it up to 5x5 once in a while to "play". Without the pump wire you are not straining the VP. If you turn the Comp off it will still function as a boost fooler and you can leave the Jhook on. I have my set to around 27-28 lbs of boost also. Very driveable. I am happy with the setup. With 4" Exhaust and BHAF I do not have EGT issues. You will love the DTT transmission when you get it.

BDR - an HX35 upgrade is always a good idea IMO for an automatic. Depending on how your temps are now, the larger 12cm housing might compensate for any heat that you might want to put to the engine - running the box on 5x5 or whatever.



Your EGT's will rise with the more fuel you put to the engine but a Comp box won't require a different turbo beyond an HX35/12. I suspect that your temps are fine with the HY35. Unless your going to be sled pulling, drag racing, or doing some serious hauling, a big turbo just won't make a positive difference in daily driving. It will help keep the temps down when hauling a big load but again, unless your towing on level 3 or more, you won't have any problems.
 
Well I have had my Comp up to 4x3 just to play a little and see some smoke. Right now I'm runnin on 1x5 and my EGTs are about 1200 at WOT. So I'm not really sure how high they would be on the higher levels. I guess I should keep, I was playing around today and had a big smile. I just want to find a turbo that can keep my EGTs in check with some bigger injectors. That's why I was lookin at an HX35 or the HTGB. So I could get by with some Mach2s, my Comp, and an HX35? I noticed PDR can upgrade the exhaust housing to a 14cm from a 12cm. Would that make a difference at all? Plus I would run the true 4" down pipe. I don't tow anything, this is just my daily driver. But I want to keep it reliable.
 
BDR - if you're not towing anything, I would say that there's no need in upgrading turbos (past an HX35) if you're only going to be running Mach 2's and a Comp box. You should have pretty quick spool up with a 12cm housing with that setup.



A 14cm housing will keep your temps down at high RPM/high boost levels but will make the turbo spool slower and again, could possibily/probably make it run a hotter around town. You wouldn't be pushing enough fuel around town to get the turbo really spooled and then, you wouldn't be running enough boost to cool the EGT's.



If you just had to upgrade turbos (because you wanted to), a Dodgezilla hybrid is going to be hard to beat in the 325 - 475 HP range. An HX40 compressor side with a 12cm housing would keep you plenty cool if you started towing. But there again, I've been down the same road as you and I just don't need to upgrade turbos right now with the amount of fuel that I'm putting out. I have to STAND on my trottle to get it anywhere near 1100*. You probably won't be running with that Comp box turned up all the time so I just wouldn't worry about the turbo right now.



Good luck.
 
So with the injectors and my Comp turned up my EGTs won't be to high? I figured if my box were on like 5x5 they would be through the roof since the turbo coun't move enough air. So boost cools and the more fuel you run the hotter the EGTs will be?
 
I think you said thta your tap to the pump is not connected. If this is the case then your comp is not doing anything more than an ex. You can turn it up and down, but it doesn't do anything.

If the Comp is NOT connected to the VP wire it acts like an EZ, but you can turn it OFF and you can chose 5 levels. I think they are 1x1, 1x2, 1x3, 1x4, 1x5. The levels bring the fueling (40 hp) in at different boost levels. I am not totally sure of the diffferent levels and exactly what and when they do what they do.



I run mine on 1x5 and get more boost and more EGT so I am sure 1x5 adds fueling.

Bob, try the 1x1, 2x2, 3x3, 4x4, 5x5 thing. Seems to work same at changing 1x1 to 1x2 etc, but is much easier to manage. SNOKING
 
My wire is tapped, I can see it. Thanks for the help fellas, I think I have enough info to start figuring out what I want in a set up.
