Engine/Transmission (1998.5 - 2002) Need advice, Pulse or Comp box

[rspinks]

I can get a good deal on a Pulse right now (same $ as an EZ), but should I spend the additional 25% to get the Comp for adjustability and/or resale value? I'm not too concerned about the 90hp vs 120hp issue for the Pulse vs Comp because I'm not into ultimate power, but I do want to be able to tap the pump wire if and when the urge hits.



TIA,



Rich

This is America, Super-Size It, go for the COMP! Oo.

You only live once.

Rich,



I started with the COMP and would make the same decision again

My thoughts exactly. When I was considering the EXACT same thing back in December, I called Piers Diesel and Piers answered the phone. We talked for a good 30-45 minutes and I ended up buying my Comp from him. Take a look at www.piersdiesel.com and www.wildcatdiesel.com. Both Piers and Rod have good prices on their Comps... and both will answer any and all of your questions. Sometimes Piers has a better price, sometimes Rod does...



But it's worth checking both out to see if you're really getting the best deal.



HTH.

If I were you I would go for the comp, when in its lowest mode it is just like a ez, and then you have 5 adjustable levels, but beware of one thing, your clutch's holding power, I slipped mine with the ez & 275 combo... ... ... ... ... . Kevin

Go with the comp. I don't think most people who buy EZ expect to want more power, but most (myself included) end up getting a PE comp for more power. Bombing is an addiction and you will probably be kicking yourself for not buying the comp.

Thanks so far, I should have been more clear in my original question. Because both the Pulse and Comp tap the pump wire let's assume the power levels are the same with both boxes. In this case is the Comp's in-cab adjustability worth the added $250Cdn? Is it really useful to be able to adjust the main/sublevels from the cab, or do you guys find that you tend to leave the Comp set at one configuration for the most part?



Duane I've been talking to both Piers and Wildcat, they're both great to deal with.



Whitmore I know my clutch is probably history past Level 1, this is in my contingency plan. BTW I have gauges sitting at home waiting for me to get the courage to drill my manifold .

Rich Rich Rich the BOMBing bug bit finally did it? You must have been hanging around Alex a little too long... ... ...



I wouldn't hesitate to get the COMP-I have been running on my EZ for the last 2 weeks and to be blunt I HATE not being able to adjust things. I like the COMP's program better than the EZ's as well..... Rod was saying that a Pulse on his and Scott's truck made both considerably noisier than the COMP did as well... ... .



My advice young grasshopper... ... take it as you will!

IMHO, the in cab adjustability is well worth the difference in price.

The PE comp gives you the option to turn it off if you like. It still provides the boost module feature even when it is turned off.



It is great to just drive around on 1x3 and take it easy, but also have all kinds of power/smoke at you disposal when it is needed.



It gives you the most flexibility.

Alright, I'm leaning towards getting the Comp now and just running it in timing mode for awhile. I'm still impressed with the stock engine so just the EZ mode will be a kick for me. Will I be able to make puffs of smoke on the level 1 settings even with stock ETH injectors?



Jason, can't wait for Cold Diesels report with the clutch, turbo, etc. If he makes it back from the coast without spinning it out under throttle that is .

I have been thinking about the Pulse instead of the COMP... which may be a bit of a waste on an ETH





too bad the Pulse is not adjustable from the Cab

Dang Cliff,

You have more control than most Bombaholics. Actually thinking of a pulse instead of a comp, never would have thunk it. 358hp isn't what it use to be huh?

358 is still fun!



Actually I stopped by a (sic) shop yesterday to borrow a few electrons in an attempt to make my Power Puck obsolete prior to Diesel Thunder... . it did not work like I had hoped to... so the Puck is plugged back in.



the reason I am thinking of the Pulse vice the COMP..... I have a stinking suspicion that with a COMP on 5x5 wil be very close to a Pulse with the jumpers on 4x4 when installed on an ETH..... however I may be wrong, but here is my reasoning behind this... . and it is full of quite a few holes



I have seen an ETH with a COMP on 5x5 dyno at 383 with DD2's... on a Mustang dyno



I know of an ETC with a COMP on 5x5 dyno at 412 with the same basic bombs as the perviously mentioned ETH... . on a Dynojet Dyno



however this is on two different dyno's. The dyno run with 412 HP, I ran at 300 HP (Dynojet dyno) with just 275's and the Puck... . I also ran at 302 HP with the same BOMBs on the local dyno here in Hillsboro which is a Mustang.



I set up the Mustang Dyno here in Hillsboro as close as I can to the Mustang Dyno where the 383HP ETH ran for my 358 HP run... so I am assuming that since I was within 2 HP on two separate dynos, and I set up one Mustang dyno as close as I could with respect to another Mustang dyno the 412 HP ETC and the 383 HP ETH runs are accurate.



Have I lost you yet... now I am even starting to get a little confused.



I think that with the COMP I could only get at most 400 HP from my truck, where with the Pulse, I would be at about 380-390. Now if I had an ETC, I would be at almost 450 HP with a COMP and my DD3's. I think you reach the point of dimishing returns faster with an ETH, so I am wondering if a COMP is worth it over a Pulse when slapped on an ETH

Cliff...

I like your open mind and thought processes.

The only reason........

To go with the pulse would be if you didn't plan on building mass amounts of power.



I have DD2's in my truck and put a cab switch on my EZ to control smoke. It makes it the same as a pulse. On a stock truck I can't see reason to ever turn it off of 3.



I thought about the comp, but it is a work truck and I have to keep it under control.

I stopped by Edge today and had my comp upgraded to a Drag Comp. Granted mine is an etc truck but man what a difference. The pyro thought there was quite a difference too, 1600+ came in no time. My excuse was I had to break that new clutch in .



Cliff,

Good luck up at Diesel Thunder. I hear that beat up green truck is smokin pretty hard now. You aren't going to let a girl beat you, are you?



Nathan

 

[jweir]

Rich,



Just to clarify my earlier post, I like the in-cab adjustability of the comp, and every now and then I can actually shut it off and remember just what the stock truck was like



It's also nice when you hook up to the trailer to "kick it up" a couple of notches just by pushing a button



Can't tell you much about the ETH as mine is an ETC.



Here is a mounting idea if you want one...

Nathan

well, if she does beat me, looks like it is time to get off my butt and do something different.



She has an auto, so I may be screwed in the 1/4, but I would love to run her from 50-100.



Keep in mind that the current score is Cliff:1, Rhonda:0 so all she could do is tie things up.



Maybe Russ could get his truck stuck in the mud again..... I have new tires, so I may do a little more damage than last time
