Please explain the advantages and disadvantages of what you are talking about with the early lockup vs regular lockup with these tunes. I'm trying to decide what's best for me and I want to fully understand what's going on, not just blindly take advice!

Thanks guys

It really depends on what you use the truck for. What do you do with the truck?

Usully the torque converter locks in the highest gear aka overdrive, in early lock up tuning the converter locks in lower gears and stays locked, this allows the truck to put the power to the ground and more efficiently. The truck will be faster at the track with a early lock up file.

But it is not necessarily the best solution for a DD tune. Depends on things like turbo, injectors, tire size, gear ratio, etc. With a basically stock truck it may be more street friendly than a built one.

Well, my truck has an intake, full 4" exhaust with no kitty and used to run on the edge juice. Thats about it for performance mods. I traded the juice for a cts insight and am shopping what to do when i order this x3 in a few days. I pull a probably 3-4k lb trailer almost every day for work but like to put my foot in it after that. I'd imagine I'll be swapping tunes fairly often between a street race type tune(i guess on the edge of what's safe with stock studs) and a whatever gets me best mpg towing this trailer. I just wanted to know what that early lockup was all about and if it woulld be best for me.

Thanks for all the help fellas!

also, the egr delete kit just blocks off the egr from going to the cooler, right? The valve stays in place? Am I understanding that correctly? The egr delete and egr cooler delete are the same thing?

any help???

A full delete kit comes with a cover plate to install on the intake manifold when you get rid of the piece of junk. I am not real sure if you can even buy one that doesent. Just make sure you tell the person doing the tunes to turn the egr valve off in the pcm.
