Replying to: kcram (Aug 03, 2005 5:09 pm) Well, thank you for that clarification KC. However, I've posted this address once before and got my hand slapped. Since I have your blessings, I'll post it here.   The name of the business is Diesel Injection Service. They are in Lubbock, TX. and maybe a couple of other places in TX.

mullins87, thanks for the help. I build race engines on gas but never dealt with a diesel before so I'm on uncharted territory. I'll take a look at the links and I agree with you on the pre-turbo pyrometer. What's nice about the new Duramax's is that they come factory with a good trany temp gauge. Dealing with the Hypertech's get me a little nervous so I set it to the lowest setting and I will be towing my 30' race trailer to Texas to give it her first workout!!!   On another note, I'm not sure why my email is private but I'll change it!!!

#35 of 391 Down side of chips by cflowers Aug 30, 2005 (2:41 am)
After doing some investigations on chip upgrades, I found that all of the chips on the market, that are available for diesels (diesel engine pickups), get their performance boosts by dumping large amounts of fuel into the engine. If you have a lot of black smoke when you are accelerating or pulling with a chip you will see what I mean. This does boost the horsepower but it also boosts your EGRs and has other unkindly effects which are tough on your engine. If your EGRs get to 1350 degrees or over your exhaust system is glowing read hot and it has already sustained damages. Thus if you are using a chip upgrade YOU NEED to have a pyrometer to keep from burning your engine up.   I own a 2004 Dodge 2500 with a Cummins, I am running a 4" high flow exhaust using a power-module which I will not name here. With the installation of the power module I picked 85 hp and 275 ft. lbs. of torgue and I get 26 to 28 miles per gallon and my EGRs never go over 1050 degrees.   Oh, I tried the Super Chip Programmer on another truck of mine. We found out that most of the ECU units on the new diesels have a hidden resident program in the eprom that if the settings are changed in the factory chip with say a handheld programmer. After 90 to 100 days This resident program will come back in a wipe out the settings and change all the setting back to the factory default settings in the chip! And you would never know it until you started checking your milage.   Cflowers Replies to this message: firekiller (Sep 03, 2005 1:05 pm) 2003dodge (Sep 21, 2005 7:40 pm) coltech (Nov 15, 2005 7:42 pm) jimmyjimjim (Feb 17, 2006 3:14 pm) steergazer (Jan 15, 2008 9:52 am)

#38 of 391 2001 excursion by frummans Sep 05, 2005 (4:14 am)
I recently purchased a 2001 7.3 liter excursion. It has a 3.73 rear end, auto transmission with over drive, has 56,000 miles. Recently drove 600 miles never over 2000 rpm's with no load on flat highway. Milage was 16.5. Is this normal? What can I do to increase it. Will not be towing and am not concerned with increasing power although it would be nice. Replies to this message: coontie57 (Jun 18, 2006 4:21 am)
#40 of 391 Magic Chip ? by allan01 Sep 06, 2005 (5:44 am)
cflowers Seems like you've sparked (well, maybe not sparked in a diesel) a bunch of interest. Understanding you're not endorsing the chip maufacturer, can you share the brand and model ? Help would be greatly appreciated Replies to this message: fishman1 (Oct 07, 2005 8:54 pm)
