  1. General Discussion
    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...

  3. 11-16 LML Duramax Powertrain
    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...
  4. 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...
  5. EFI Live
    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...
  7. 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...
  8. EFI Live
    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...
  9. EFI Live
    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
  10. EFI Live
    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...

  12. 07.5-10 LMM Performance Parts Discussion
    Ok guys, this may sound like a really stupid question, but that's what forums are for I guess. Is it possible to have my truck tuned with EFI Live from a performance shop with their custom tunes without having to buy the software? Sorry, I am just confused as to what the purpose of buying the...
  13. General Discussion
    Ok, so I'm going to start this thread, not for me, but for anyone who may have the same question... what are the pros and cons of modding with aftermarket parts and voiding your warranty, and is it worth it? Also, IF something major were to go out (i.e. tranny, rear end, injector) how much would...
  14. EFI Live
    I just purchased EFI live. :D I was told that I can just download the software instead of using the CD in the box and use my PIN that comes on the box. So my questions is: Can I buy a netbook to use for EFI live? Netbooks do not have a CD drive, but will I ever need one? Also, How important is...
  15. EFI Live

  20. 01-04.5 LB7 Duramax Powertrain
