    I’ve got an AutoCal V2 that I bought used from PPEI that has only been used twice. I’m not sure what this is worth or if anybody is even using the V2 anymore. Just looking to get rid of it. If someone would give me a price on what it’s worth or willing to buy it just PM me please
  2. VIN Check
    Hey guys, I purchased an LMM that was deleted by the original owner (I bought it from second owner) and he didn’t know which position was for which tune. It has the dsp5 switch and I just want to make sure I’m not going to be towing my toy hauler in a race tune lol. If anyone could help me...

    So I am looking into getting the SAC 45's (since the SAC00 are no longer available) and I am wondering if I am going to need to upgrade my lift pump for these bigger injectors. The truck is completely stock and it has an EGR so I don't know, if going with bigger injectors, is there is anything I...

    This will be a long one. Please read all of it. I have had this truck since new in 2007 and put just about every mile on it driving the country from worksite to worksite.

    I have a Black Bear Performance AutoCal efi live for sale. I bought it back in like 2017 and never put it on my truck because I was out of state. I have sold that truck and it has just been sitting here collecting dust. It was for a 2015 Silverado 5.3L but they told me they could be used on...

    I have an lbz which I bought from an older guy 2 years ago. When I bought the truck it has an edge insight cts for monitoring. The guy stated he had a stock optimized tune on the truck and other than that no other types of tuning. So I’m wanted to get efi live here sometime soon. I know that I...
  9. EFI Live
    Hey all, in need of help or guidance. I have a 2001 gmc 2500hd, I got efi live from kory at ppei. It came preloaded in the v3. Hooked it up, read the stock tune, then did the full flash. Trucks runs great but now the a/c doesn’t work. They wanted my stock tune to build new ones off of that I...

    Hey guys, I’m trying to find out who does good tuning for efi live in the Orlando FL area? Or just who still does good tuning for EFI in general. There’s a lot of companies and I’ve seen a lot of mixed reviews. I’d also rather have it dyno tuned if that’s possible with EFI so there’s no...

    Hey all. I have a 2014 LML. Deleted, EFI Live, intake and 5 inch exhaust. Today I ran to pick up my kids after school, but got an emergency call at work so had to scoot back home to get my work vehicle. Got on her a little to get up the driveway as we had temps in 40’s today and nothing but a...
  13. 01-04.5 LB7 Performance Parts Discussion
    Hey guys! First post here. I got an 03 LB7 a couple months ago and I'm thinking about getting a new tuner. Right now, it has an edge juice with attitude control module. This seems like a pretty old tuner that what I can find came out around the time the truck did. I'm looking at EFI live. The...

    Hello, first post here. Bought a 09 LMM Silverado a couple weeks ago, my first Duramax. Previous owner has some tunes on it with a DSP5, only info he could give me was that each tune would progressively add more power. He claimed the first one above the stock one was 500 hp and the highest one...

    I currently have a dps5 switch and about 700hp on mostly stock equipment. I drove truck with intercooler disconnected. Not knowing it would damage something. It smokes heavily now. So i already had collected parts; 68mm cheetah turbo, 200 over injectors and stroker cp3. A few yrs ago. Since the...
  16. Performance Upgrades
    i am running a stock lift pump and on my efi tunes (especially my 90 & 150 tunes) it seems as though my truck has lost some speed. if i get into the pedal about 50% of the time it seems to be a bit slower and just laggish in general it also hazes smoke through acceleration. is this my fuel pump...

    I am fairly new to the Duramax world, but have quite a few hours of reading on here. From my research on here it appears that the V2 is for data logging and retrieving the stock programming for use by a tuner. So, I'm thinking that I need to purchase EFI live first and use the V2 to upload my...

    I see a lot of guys making 50hp tow tunes, 80 hp tow tunes, 150hp race tunes and so on, so how do you know the HP for the tune when you create it? Is it just based on what you know a truck with similar modifications has will do or is there something in EFI that tell you this? Thanks Matt

    I was wondering what effect EFI tunign has on the tow/haul transmission mode and how it all interacts with say a turbo brake EFI tow tune? Also, does the EFI tow tunes with turbo brake change the shift points of the tow/haul transmission mode? I have used my truck to tow a 6k camper and put it...
