I have a 2005 GMC LLY and I am looking to add a compound kit to it. I tow a lot to the track (truck/trailer just over 24000). Looking for any input. Thanks
trent on this site is one to pm about that Keep the stocker and run one of his 75mm kits. it will work great
I'd look into Trents or Nathans kit (MPI). As far as tuning, I would look into EFI Live, or have someone make you a tune to run with the twins. I know that trent can set you up with twins and the tune to run them. Also are going to want to have your trans done if its not already. I'd do that before the twins/better tuning
