Yeah, since you point it out, maybe it doesn't make that much sense. It sounded good for a second though.

Never been to Moab. Wheeled all over the East coast but this will be the first trip west of the Mississippi. We leave in three weeks and I'm counting the days.

the factory intake is good to 500 hp or so, and usually doesnt do too much in the way of egt reduction. a muffler will. a module tends to increase egt's with a stock turbo when towing, most modules perform boost fooling which allows you to get higher boost from your stock unit, which will lower egt's, but when the boost gets too high on a stock turbo, you are shortening its life, and excessive boost will make higher temps. the stock turbo isnt efficient about about 35psi. a better turbo(not twins phil, though its a good idea )will lower egt's when towing. a turbo will benefit from having some form of better fueling, either from a 'box' or a programmer.

i started with gauges, then a 'box' then intake, exhaust, lift pump, and finally a turbo to drop the egts.
the temps were manageable with the quad box. but i had to slow down and watch the temps when heavy. it steady got better with mods, but the BIG reducer was the turbo.

I will definetly hit the broken ore.

Dodgezilla, you make some good points and I look forward to doing more mods in the future. Just trying to balance out spending on the Jeep, the Dodge, the wife, the house, the dogs, and did I mention the Wife!!!!

I find that whatever I spend on the toys, I have to spend twice as much on the wife. Well, this is the price we pay.

sps62/14 from II. the 1 requirement that i had when turbo shopping is the direct bolt onto the stock manifold and exhaust elbow. Which means it will bolt the pacbrake up just fine. So yes sir, fits great.
Phil, i had to slightly grind(3/16") off the end of the pacbrake cylinder bracket because it was touching the compressor outlet. i will try to get a pic of where and how much tonight, since i dont seem to have one in my gallery.

The "Cat" under the truck does not help matters. I am prepping to haul my two John Deeres to OH in a couple of weeks, and i can assure you that my "kitty" will be GONE!!!!!.

I used the 4" hole saw I used for the B&W and cut out the bottom of the stock air box. The filter minder doesn't get sucked down anymore and I'm pretty sure egt's don't get as high.

Here's my solution for towing heavy w/ an '06 quad cab CTD 4x4: I did the air filter mod (4" hole in bottom of air box and piece of dryer hose), added a Smarty (EGT's too hot, w/ Smarty alone) added a quad boost fooler and ---VOILA!!! Smarty on 5, towing a 3 axle toy hauler, grossing about 23,000# and standing 13'4" at the top of the A/C's, the hottest I have seen is about 1050 post turbo (in PacBrake PRXB boost port) and the thing runs like a champ. 55 mph in 5th gear in a G-56 up a 5.5% to 6% grade from a standing start at the bottom within about half a mile. Boost at about 38psi. No smoke except on the shifts which were not speed or power shifts. No turbo bark either. Just a really, really nice and responsive set-up. It would have just continued to accelerate but I got behind a big rig with oncoming traffic and that was that. I think it would hold 70 on a 3.5 or 4% grade in 6th gear with 34.5" tall tires and 3.73's no problem. Tried software #7 but stock clutch said "It ain't happening" -- no way would it hold the torque just walking into the power with the clutch fully engaged. Don't really need the extra power anyway, as when you hit a grade on the freeway, cruise on at 70, the boost just starts climbing, EGT's go up to about 850 or so and truck/trailer just fails to slow down until the exhaust brake starts to turn on going off the other side. It works just like a truck is supposed to now. Dodge oughtta sell 'em set up like this from the factory.

A 5" exhaust is probably your cheapest way to lower EGT's. Modding your stock box will help also. Removing the cat is not helpful.
