HemiTronix

So I'm curious, after reading over their website and the magazine article how realistic do you think those dyno numbers are? I've heard so many different numbers for the Hemi, though I know that has something to do with the dyno it's actually on. 50 hp on just a tune alone seems a little generous to me. Generally speaking I thought that there wasn't much to gain over the factory tune with a factory ECU or everyone would be out there getting a handheld tuner. I've seen one dyno'd with headers, Indy intake, and TBI only pull 400, at that was without any accessories running.
