I just used the Stillen cable to flash back to stock, and then I flashed a custom tune over that. Yes, the Stillen tune is locked, but you don't tune over the Stillen tune, you remove the Stillen tune, and then flash the ECU as if you're flashing a stock ECU. The annoying part is that you can't do anything with the Stillen tune, so once you remove it, you essentially have to buy whatever tuning software you want to use, as if you don't have anything at all. In my case, ECUtek doesn't work with my ECU, so I had to buy an UpRev Tuner kit (license AND cable) from someone else, and start from scratch.
So now that that's out of the way, what kind of power did you make? Videos only show the pull, not the results.
