EFILive AutoCal V3

2020 Ram 3500 almost takes off like jet, stupid quick!

I am doing an EGR and EGR cooler delete on my 2005 GMC 2500HD LLY truck.
I was finally able to download the tune and the BBX (?) files yesterday onto my new AUTOCAL V3.....Installed in my truck and all is good......

Extremely helpfull to a fault, the first time I called was after hours I didnt leave a message and received a call righlt after I hung up and was asked if he could me. Very helpfull and responsive .. Thank you.

Easier every time

Purchased an Auto Cal and a couple different tunes for a couple of trucks. Customers service was fantastic, tunes runs well, just got to watch your EGTs on heavy tow tune (switch #2) for there is no defueling and EGTs can quickly get to 1600 if your not watching.
