What is THE setup for towing?

[Chace TX]

My 2001 just rolled 22,000 miles. I cannot stand to drive anymore without adding some power. Gauges are on the way. I was set to order a Comp, and called Autowurks on their special. They were all out, and told me that I did not want a Comp if I was going to tow, tried to talk me into an EZ. I declined and am now undecided. I don't care about racing, just want a truck that will get better than 10mpg towing, and have enough power to pull the hills without downshifting. I want the stock clutch to last a good while. Will the clutch live with an EZ and DDII's? What kind of mileage can expect with an EZ, or an EZ and injectors towing 10k@ 65-70mph? Not asking for a miracle just something that will make me glad I traded off my 12valve.

The Comp is adjustable so if your EGT is to high towing you turn the box down. I have pulled around 10K numerous times with my truck with the EZ only. I haven't ever really tried to figure that actual mileage but my overhead console(which is wrong) says 13MPG on the highway and it reads a little high because of the EZ. I don't have any trouble pulling that much wieght at 75MPH at all. My next step is some DD2s.



I have driven a truck with a stock clutch that had an EZ and DD2s. It didn't slip but was close. You should be fine with just the EZ and DD2s IMHO but a comp and DD2s will slip for sure.

The clutch should live with the EZ and DDII's if you keep your RPM's up, but why spend all that money when you can have that power on level 2 of the edge comp for less money.

Check out piers site $575. 00 for an edge.

I have learned from reading on here that an EZ and DD2s is going to give you in the area of 300-320HP at the wheels. A PE comp on level 2 will give that much??? Seems kinda high to me. I have an Early 99 so the VP44 is a little of my concern for not adding a heavy fueling box.

I had an EZ and DD2's. Excellent towing combination. However, I just purchased a comp. As stated above, you can adjust the comp for power and egt's while towing. But on 5x5, your clutch will not be happy

I should of stated with the Comp you can adjust power levels and still save money.

Sorry for the confusion.

I'm pulling 14,000 and mileage towing is 9-10 running 70-75mph. Maybe could get over 10 if held it to 65, but I don't slow on any hills either. The reason for bigger injectors is you're pushing more fuel so having an injector that flows more fuel takes a-lot of strain off the pump. See my sig for my setup; not mentioned is the 4" turbo back exhaust which I'd recommend for staying cool (or keep an eye on the EGT's on hills).



Your stock clutch might last for awhile but keep some money set aside for replacing it. Any power enhancement for towing is going to burn out the stock clutch before too long; unlike people who turn up the power that don't tow you're going to put that power to the ground all the time towing vs. only occassionally w/o towing.



ps: my 12v would get 12-13 towing the same trailer; but I ran it slower too. 65-70 (12v) vs. 70-75 (24v). And my 12v was a 2wd vs. a 4wd in my 24v.

I have the VA box & 275's. See sig for other goodies. I like this settup. The EGT's stay in check, but the clutch died. Some say the VA box is the best for the truck as it doesen't overstep the boundries of the computer like some of the bigger boxes can. This settup would be conservative, and still get great fuel milage. 20-21 empty interstate, 17-18 around town. Towing in the mountains 11-12, towing on flat land 12-13.

I can tell you that in the hills of Tennessee, with the mods I have, see sig, and grossing 17-19k I can start a hill at the bottom at 55 mph, and top it at 75+, the only problem is trying to wipe the grin off my face. Its a good combo for towing. I have 3. 54's so 4. 10's would probably do even better.

With our combo (ETH/DEE, 4. 10LS, EZ on level 3, BHAF, 4" exhaust), when towing our 5ver we're getting 10% better fuel mileage than stock (11 MPG at 70 MPH), 200 degF lower maximum pre-turbo EGT's (1050-1100 degF vs 1250-1300 degF stock) and pulling hills in the Texas Hill Country at 65-70 MPH at 1/2-2/3 throttle in 6th that were previously 55-60 MPH and full throttle in 5th.



Since we're running stock injectors, we've had no clutch problems. Our truck isn't set up for racing, but pulling our 13,500 lb GVWR 5ver and running at an actual 21,380 lbs GCVW (21,500 GCVWR), it's a towing son-of-a-gun with these mods.

Chance,If Iwere you,id get the comp,dont tap the pmup wire if you dont want to,but the power is there if you want it. The comp will need to be on level4 to ge the same power as an EZ,and dd2's. Had this setup for a while. The comp by itself on level4 or 5 will give you higher EGT's than thr dd2'and EZ,at the same power level. The fuel pump is delivering a blg shot of fuel thru your stock,small nozzles,this takes more time, with small injectors,so it effectively makes the timing late,and the EGT's get high. With DD2's the fuel is delivered much quicker,becuaei t can flow much faster,this gives lower EGT's and more power. with the comp,just tow on level 1,it will be plenty of power,I would not tow on anything above level 3,you should be fine. When iwent from the ez to the comp,the first time i blasted it,I couldnt get the grin off my face for a week,LOL.

If you intend on keeping the stock clutch in, then you can have either injectors or the EZ, but not both at the same time. The ETH clutch simply won't hold both mods (the max power of the comp is rated beyond the limits of the stock clutch too). I notced a couple of ETC guys saying the clutch should be okay... the ETC clutch yeah but not the ETH clutch.



If you're not interested in racing, then what good would the comp be that you have to keep it turned low because of high egt's during towing? Sounds like the EZ will be of better use for towing.

 

[Snow man]

Mike,I think he has an ETC.

 

[DRR-24V]

I'm With RustyJC And MikeR !

IMO the Edge EZ will do anything you want when towing. I think even then you will have to be careful with the clutch if you want it to last.

 

[MikeR]

Oops, thanks Snow. I quickly glanced at the '2001' in his sig and assumed it was a 6spd. That's what I get for ASSuming and not looking closer!

Go with the Edge Comp

Chance TX: I'd go with the comp box. Piers has it for $575, and if you don't hook up the pump wire it will give you everything an EZ will, and you can turn it off or adjust it from inside the truck.



Then if you decide you want more power, you can add the pump wire. But you will need to upgrade your air filter, and maybe your exhaust to keep egt's under control when towing.



The ability to adjust the box from inside the truck even when on the move, is a big advantage.



If you find your clutch slipping, just adjust it down or turn it off, or best, drop down a gear.



Just my $. 02 worth. Greg L.

I have to agree with some of the earlier posts. I have dd3's and an ez, and it tows great with a 9-10 k trailer. no egt problems at all, however, most of my traveling is at or near sea level. I love the ez box, however if i was doing it over, get the comp box. you dont have to tap the wire right now, but you will want to some day (trust me) the cost difference is negligible for what you get IMHO. get the comp and dd2's, or dd3's and if you dont tap the wire that 5 speed clutch will probably hold up pretty well if you are nice to it while towing. just watch for the low rpm foot to the floor acceleration runs, thats what will smoke the clutch fastest. the 6 speed clutches suck, mine went bye bye at 1800 miles. but i am a led foot with or without a trailer. It is just way too cool passing cars on a larger hill while you are towing a trailer. just my . 02

 

[HiPerf360]

I would go with the comp and DDII's, I pull 20k all the time with my Blue box set at 30% and don't have too many EGT problems. If the temp starts getting to hot the box starts pulling fuel out until it is back to a safe temp. I think this is the best setup for pulling but I could use some more power... LOL

 

[Chace TX]

Thanks

I thought I was never going to get back to the computer and read this. I would really like to keep the transmission, clutch and everything else in one piece for a long time. I don't think I will ever need more than the EZ and I could sell it to one of my buddies if I needed to get a Comp. I just ordered one from Autowurks. Can't wait to get it on this slug.

Have the same setup...

I went through the same process you did in deciding to get an EZ... I have the same setup as you do and had the same concerns. I installed the EZ and set it on 3. I tried 2 and decided that 3 would be okay with my setup. If you have a lead foot, 2 might be the best setting... . GOOD LUCK...
