03 LB7 Duramax, Tell me what I need!
 

I just purchased a 2003 GMC Sierra 2500HD extended cab. It has 195,000 miles on it and is bone stock. It runs like a top, the Allison shifts smooth as can be, and looks like it just came off of the show-room floor. It has never pulled a thing in it's life, but that is about to change. I won't be pulling huge loads, just a stock trailer with some calves in it about once a month. I am wanting to do a little bit to the truck, not necessarilly for the pulling, nothin too ridiculous though. I've heard good things about a PPE programmer or maybe the ATS. I am putting a 4 inch straight pipe on it and probably will get a cold air intake. It would be nice to be able to roll some smoke too. I'm just looking for a little advice from anyone that is willing to give it.

EFI Live would be a good thing to look into. maybe a lift pump. it all depends on what YOU want :tu:

welcome to DB

efi live, ppe, banks, bully dog, quadzilla, hypertech, superchips, or any small little programmer will so also, untill the big bites you lol

the intake can be modded for free.

I have the same year truck. But a single cab ZF-6 tranny. I have had great experience with the predator programmer, a BD flowmax lift pump, straight pipe exhaust, and a Brute Force intake. Lots more turbo sound, a fair bit of smoke for tail gaters, and loads of power (for the amount of cash) Full throttle launches in 2wd are useless(blows the tires off) just IMO.

PS: I will tell you from experience, no matter how flashy it looks....don't go with edge. I spent about 4 weeks just trying to get the juice w/ attitude to work and then I gave up.

i like my superchips flashpaq for mine. i do same as u, little towing but mainly dd.

only reason i went witht he flashpaq is i got it off craigslist for 100 bucks.

no smoke unless i stop on it from a stop with the flashpaq turned all the way up. and even then it is just a puff.


i also would do the intake mod to the stock box. works well, little more turbo sound after i put the drop in k&n in it too.

You must of had a bad unit. The edge is very simple and only takes a couple of hours to install (Running the pyro takes the longest). I have been using my edge for two years now and am very satisfied with it :tu:

I had the same problem with the edge with attitude on 6spd.:humm: Ive also ran Bully Dog and now have a PPE. Ill personally never get away from PPE unless of course I go EFI live.:tu:

hands down go with efi live if u want big power

i had hypertech not a very good programer im tuned with EFI Live now and i love it

idk i have the edge with the attitude i think it took me like an hour to hook it up 4 plug ins and run a wire to the cab the egt wire definatly takes the longest. 4 what you say you want the chip for i would say go with the edge its a good chip for your money and it power at your fingertips with the attitude monitor. the ppe and ats programers are good but there not on the fly ajustment witch would be something you would like. and efi live is way up there with the big power and need to no what your doing with it or it can really f*** stuff up. i mean thats just my opinion. hope this helps

i have also found a website www.kennedydiesel.com and there they have a bunch of things that modify your stock parts to make them better some of them are mods to the air intake and fuel pump and in my opion help out quite a bit considering they dont cost anything and are just upgrading parts you already have.
