What is the best/safest programer/chip for LBZ

[mark45678]

Any empty mpg changes? Should be across 20mpg on a flat road at 60-65 mph.

The way my truck was before the tune I was seeing 15~16 mpg with a heavy foot at speeds 75 ~80 mph , Now its 17+ MPG with the last 3 tank fulls empty. Towing shows a solid 1~1.5 MPG better then stock with 9200 pounds of 31' holiday rambler in tow. Power to spare in the hills and keep me smileing .

Thanks again John !

A well known GMC dealer in Ogden Utah has signage on its new 2007 Dmaxes that say in big block letters "Edge Products". Now is GM going along with this or are any problems that might occur because of the product being covered at the dealer? I know that some time ago in another city near Salt Lake that they were also advertising Edge. Whats up? Is GM now suddenly ok with this? Me thinks Not. Maybe the dealer is closing the deals with a disclaimer.

Any ecm / sensor fooling devices is going to be a BIG issue with GM and the EPA , again out of site / not in the truck at time of service or inspection time and you will be fine. I would never by a truck with a dealer knowing it had a power adder on it , I would go to the aftermarket company so there was NO paper trail that could be connected !

I should also add to my fuel milage statement above that this is a 4x4 crew cab truck with a cap and ladder rack on the bed and 800+ lbs in the bed of the truck every day .true is not as high of mileage like some owner that claim they get more then 19 mpg , but there is no way "they" are going to drive beside me on the highway and the speeds that I travel and live up to there claims. Drafting and driving slow I dont question it adds 2~3 MPG , I just dont have time to wait for a truck thats willing to run over 70 mph.

i have been working with a local diesel performance shop and quadzilla is BY FAR the best programmer available for the duramax. I thought EDGE was good...and it is, but we did not see the same performance gains as we did with the quadzilla stealth II. If you get the race version of the programmer ($300 more...), hang on. And you better have a heavy duty torque converter too. Banks needs to go back to the drawing board. We only saw a HP increase of ~20hp on level 6!!!! Whats the deal with that???? Bullydog was ok too....but nothing compared to Quadzilla Stealth II. They deserve a pat on the back. ~200hp at the rear wheels....programmer only....WOW

At 200RWHP gain that puts you well across 500RWHP. I really doubt that the OE Garrett turbo can move enough air to get there, but I could be wrong...

I'm sorry and i stand corrected. they did modify the wastegate to pump more PSI, i think they put on a banks??? I'm sorry, i dont know much about this since im just getting into it....

but on the other hand, i just can't believe the possibility of diesel engines...wow

waste gate ???? LLY , LBZ , LLM motors dont have "waste gates" they use varyible geometry turbos that change to amount of slip in the exhaust housing.

If your correct they most likely are tuning a LB7 truck 2001 ~2004 vintage motor or they are useing a old school turbo ....
