No one would care about the 50 bucks if efi supported deletes.
Wht do you mean IF? They DO support deletes, just not for those in the US. And it has nothing to do with the customers, or lack of them wanting to offer it, but everything to do with our EPA. As to obtaining LML tunes, I can't blame people for charging for them. It's not like they can just go out, plug into the data port, and read one out for you. They have to get an ECM, open it up without destroying it, solder the VERY FRAGILE circuit board to enable reading ability, flash the required tune file using GM software to the modified ECM, THEN read it out using the jumper and there own 3rd party obtained software and equipment. So it's not jsut a simple ordeal to do it half way legally. I just lucked out, and got those files before they were deleted after somebody north of the border had hosted them on 4share for all to find and download if you felt like waiting through all the popups, ads, and clicks to get them. It's no where near a complete tune file repository though, and those tuners you pay for a file can get you the hard to find tune files.
I'm just trying to pay it forward as I still remeber being green to tuning, and having some others help me to wrap my head around this, as well as several people helping me out with tune files over the years, and still to this day having others who know more than me help me out with problems I had.
