Exhaust question for 2004 D-max

[tasco]

Right now I am buring approx 100 liters per night pulling a trailer with a forklift on it approx 7000 lbs. I get approx 500 km out of my 100 liter tank. I am running a Van Aaken chip right now

I figure by eliminating all the back preasure from my catalytic converter and increasing the flow through my exhaust system, and updating my cold air intake I can get an other 50 to 100 km out of a tank of diesel

by the way I am looking at a Magna flow 4" stainless system from Unlimited Preformance in Calgary here, and a AFE Cold Air intake system SKU # 54-10612

With the the exhaust and intake installed I think I can pull my trailer with my chip set on high with out worrying about over heating my turbo

Tasco, I would recommend some gauges if your adding that and going to be pulling... It is good to monitor that pyro temp when your working it!

The Allison Transmission rebuild starts at about $5000 and for the bullet proof version its about $7500, with the chip over level 2 and pulling a trailer expecially a larger trailer be prepared to be doing a Transmission, I did. And yes you need EGT and Boost Gauges as well. The edge with attitude has a warning system that you can set the limits so it makes a noise. With my 02 I had the Edge with Attidude, Magnaflow 3" exhaust, K&N intake, I would often see between 630 - 690 km tank, with the chip on 2, And remember the GM only has a 100L tank, the most Ive ever put in was 94L right to the neck, except for one esso station pump says I put in 109L

Well I havnt got my fancy exhaust system and cold air intake yet.

Seems like my truck started going to limp mode for no reason, that I can figure out. Changed fuel filter about 3 times, replaced the water sensor at the bottom of the fuel filter, because it seemed that when I played with the conection to the wiring harness here that the truck would stop being in limp mode after I play with this conection.

Right now it is in the shop, I think it is a harness issue. It is giving weird codes number 7 and 8 injector codes came up a few times, can't remember what the mechanic told me what the codes were, I cleared them a couple of times now. Truck dos'nt smoke period and runs like a top whin it is'nt in limp mode.

Any one have any ideas? No aftermarket parts till it's fixed.

2004 d-max, LLY engine

Sounds Like the samething mine did ,went into limp mode and had barely enough power to pull it's self down the road.What it was 7 and 8 injector harness wires had open circuit right at the injector.All they did was cut the wires off and put a new plug on.From what I understand it is a common thing with those to go out.

I agree as well... Cold air intake is a must! especially if you cut out your cat! You need to balance air in with exhaust out.

I wouldn't bother with an intake on the Duramax unless you're planning on making over 500rwhp. Won't help. Exhaust is a must though to get your EGT's down.

Tranny is your next biggest worry. You may find that you get the best mileage on a higher hp setting, IF you can keep your foot out of it.

try dieselplace.com for any questions, plenty of threads to search and solid advice on there.
