3406e 40 pin ecm

Hello All,

this is my first post. I recently purchased a 1998 379 last 6 of the vin 444937. It came from the factory with a 6ts 550 cat and an 18 sp. I don't think it pulls well at all. It is a factory 4 axle double-framed truck, and I routinely gross 200,000 lbs.

I brought the truck to Cat yesterday and found the serial number on the engine to be 5ek72847. not the original serial number of 6ts13722.

In checking he 5ek serial number, I discovered it was sold to the man I bought the truck from. He claims, cat did a compete inframe in the truck in 2005 and put the new plate on the old block. is this how it's done?

the 5ek72847 egine is a 475 hp in the computer, but with the perf. spec of 2T7447, its 550 hp.

I am assuming it now a lownox ecm settng, and I need some help.

What can I do? Mr. Haney sells the programs, I believe, pre-lownox and up to 600 hp.

I need more power and need it fast. The truck is scheduled to pick up a control building this wednesday, 2/16/2010. and going to West Virginia, I'm going to need more than this puts out. currently, its running about 900 degrees at 29 lbs boost. that's all it gets.

any help would be very much appreciated.

 

do you have a ecm there that you can program and ship with a core fee/deposit , of course, and I can ship mine back? as you can see, I'm in a bit of a hurry? thanks

 

had my ecm sent to Mr. Haney. in about 2 hrs he ha it back in the mail. Put in a pre-low nox 601hp 2050lbs brakesaver program. Let me tell you, it made a BIG, BIG difference. If you need a program, he's the manto call!!!!
