Ok, I want to know what the BEST intake & exhaust upgrades for a LLY Duramax would be. I have a programmer already, but think I'll be getting an Edge juice with additude.
What have you done & how does it perform?

Jason,

PM sent. Hope that helps.

Buck,
I would like to hear your opinion on this. Please let us all know.

Dangit! Questioins like this are a no win.

Just gave him the normal names that seem to be preferred. AFE, True Flo, MBRP, Banks, Magnaflo, Dynomax, and so on.

Not everyone of these products fits into every person's budget. I try to feel out the client and see what meet's their needs within their budget.

Did I do a good job of dodging the question?

Buck...I guess the warranty is void after you do this stuff correct????....anyway....how much power can one get out of a new duramax.....bernies rig???....plus it needs air ride all the way around...kershner air ride..or something....torque ....I am a torque monster

Wow, the "warranty" question. Ranks right up there with taxes for me.

I ALWAYS tell a customer the warranty is between them and the servicing dealer. All dealers have a different take on different items. My local GM dealer could care less. Put almost whatever you want on it and he'll take care of it if there's a problem. Go to the GM dealer in the next town and he will freak if you put aftermarket wheels on a Duramax.

In short, this is a VERY gray area IMO. Open communication with the dealer is what I recommend.

I personally don't have any issues with my dealers that my customers have to worry about.

Air Ride...I have access to Firestone. None of my distributors carry the brand you mentioned BM. Sorry.

Power gains....This should be in the 15-25 hp range. This is what I consider a realistic number. I won't balloon this number to make a sale to someone. For the most part the intake and exhaust are usually added to compliment a tuner or chip. In this scenerio the gains are substantial to say the least.

I don't have any dyno data to give out realistic torque numbers on just an exhaust and intake upgrade.

I do however have a full dyno run on a brand new 2006 Cummins in stock form and running the new Triple Dog by Bully Dog. A customer agreed to have his truck guinea pigged to do some tuning with a local manufacturer's chip. He took the opportunity to get some numbers on his Triple Dog while he was there. Unfortunately the numbers I have on the sheet are all HP numbers and no torque.

Buck

Wow...does not look to promising.....jeeeeeze...25 hp....why touch it at all....dang!!!!!.....what does lly mean

You need to check out http://www.dieselplace.com/forum/index.php
Lots of good info there.

The LB7 was the first generation Dmax. It was replaced by the LLY which has been recently replaced by the LBZ. The current rumor has GM Upgrading the engine again in 07. I had very good luck with my 01 LB7 Dmax and recently traded it for an 06 LBZ with a six speed Allison.

well...dan..you seem to know quite a bit about these trucks and motors..it is a 2005 4x4 automatic ...4500 with hauler bed...my truck guys are cursing me for this truck.....my only other choice is a 550...i know it needs total air ride installed....i posted pics on other thread......what is your opinion....interior is a little cheesey and like thin....but underneath is killer...everything is some garbage these days.....????opinions???

Looks like a killer rig. My knowledge is very limited on these trucks. Lots of lurking on truck forums helped me make my decision to buy a GM. I had zero problems with my 01 Chevy LB7 Dmax. I traded it in with 89,000 miles and the only thing I ever did to the truck was change the fluids and filters. Even the brakes were still original. I love the Dmax and can't say enough about the smoothness of the Allison.

Unfortunately what you are looking at is totally different from my 2500 HD. You need to get opinions from 4500 owners. I am not sure what things are done differently on the 4500. I would put a post on the Diesel Place asking for opinions. Let them know the build date of the truck so they can figure out which engine is in the truck. They will be able to help.
