First off thanks for all the help guys. I have learned a ton of info on this forum in the last 24 hours. Most of you probably have read my first thread on here so lets get into it.fficeffice" /><O></O>
<O</O
I was considering a 60 hp eco/tow flash for my grandfather’s 96. However i know EGT’s may become a issue with mountain driving. Some of you will say just put a pyro gauge in it but that’s just not a option. My grandfather is in his 70s and a gasoline guy. He would probably never even look at it. So with that being said I am looking at options to boost low and mid-range power on a budget. The intake and exhaust sides are done but everything else is stock on the truck. It is also a 4EOD with 4.10 gears.<O</O
<O</O
I have read up on the 14.7K, BB (fuel shim), and IDM Mods all look like good possible options. After reading a few right ups on all the above I think I can tackle them. However I want to make sure I have a good understanding of them first.<O</O
<O</O
The Fuel Shim “BB” mod basically increases the fuel pressure going to the injectors. Your goal is somewhere between 68-72 psi. It seems like this is a good mod for older trucks that may have lower fuel pressure due to wear and tear. <O</O
<O</O
The 14.7k mod tricks the HPOP pump into running more pressure to the injectors. I am assuming this is similar to turning up the rail pressure on a common rail or CP3 system. The increase in pressure allows for better atomization of the fuel creating a cleaner and more complete burn. I am also assuming this will not increase EGT’s and may in fact lower them slightly.<O></O>
<O</O
The IDM Mod basically allows the injectors to respond faster. This helps the truck become more responsive. I also read one thread where it states they also stay open longer. Once again if it helps the truck respond better and does not raise EGT’s I am all for it.<O</O
<O</O
I still have some research to do and will only take on one at a time if I get positive feedback from owners. If any of the above mods make the truck start better, increase its response, run smoother, or add any low-mid range power I will consider it a win. The only catch is I don’t want to trade reliability or higher exhaust temps to do it.<O</O

 

None of the free mods are gonna give you EGT problems.
You need to add more fuel to do that.

 

Thats what i figured but wanted some advice from the PSD guys first

 

Biggest thing that isn't free is just to put a good exhaust on it from the turbo back.

If your gonna spend any money at all, that would be number one.
and number two would be something like a 6637 kit for the intake.

You'd have a sweet truck without a whole lot invested.

 

How much heavy towing does your grandfather do? I'd wait for input from the folks that live in the mountains, but I would guess that a tow tune would be relatively safe, especially if he's not towing.

 

6637 filter kit and 3 inch down pipe are on order and should be here by the end of the week.

As for the towing he pulls loads any where from 4000-8500 lbs. Slow steep turns.

 

Thats not heavy, so a medium tow tune would be just fine id think. I'd still urge you to put a pyro in and urge him to use it lol.

 

See that’s the issue. I can run my stock turbo LB7 on a hot tune and watch my pyro all day long. Younger diesel guys can and probably enjoy watching the needle. But it would be a waste of money on his truck. If it was a intercooled truck I would be all for it.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-comfficeffice" /><o></o>

 

What does an intercooler have to do with it lol? Its not about having fun watching the needle bounce, pushing a bone stock truck hard enough pulling and you can reach 1200*. With a tune, a load, and a long steep grade it'll have no issues getting there. Prolonged high EGT's to the tune of 1250+ can warp internals, ruin valves, and even melt pistons.

 

That’s what I am getting at. He will not watch a pyro gauge so I am afraid that even a tow tune on a long hard pull might get up there. If the truck was intercooled to help keep the EGT’s down a little bit I might feel a little safer about running the DP 60 hp tow tune. And for right around 100 bucks it seems like a great deal.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-comfficeffice" /><o></o>

 

Ahhhh I misunderstood, i thought you meant if it were intercooled you'd put a EGt guage in and i was thinking.....if it were intercooled youd have LESS to worry about lol

 

Now we are on the same page

 

Still kind of split to be truthful. Looking at DP tuners web site it kind of sounds like there 60hp tow tune would be perfect for him as long as EGT’s don’t become a issue. I also like the adjusted shift point idea to help hold the rpm’s in the power band.

 

Honestly, You can go to PepBoys and get a decent EGT and hose fittings for less than $100. Now depending on the store (mine does sell autometer), it might not be the best one. But its still better than not having one at all. Plus the one down the street from me sells 3 pod gauges right off the counter.

My dad was the same way with gauges. But, after being educated on their importance. He went out and bought a set of his own and looks at them religiously. Dont take your grandpa's attention span for granted.

 

With stock injectors, you will only see a max of 40ish hp from tunes.

Shift points are going to be the best part of tunes though.
