Title says it. how are they doing it without "pro tuning" or delete parameters provided to US based tuners or even out of the US based tuners. There's about half a dozen or so US based tuners providing this and the claim is that they are not using addition software or equipment to do so. So how's it being done and where can I get it? I get requests daily and am missing out on a lot of business due to not having it. I hear about .CAX but was also told that that has been disable or taken away from the EFI live update.
