First off, I will be getting a 3.4 MPS and a PCM. I am going to for now get an off the shelf DHP tune through 3800performance.com My question is what is the difference between the 1.0 file and the 1.5 version? My other question is does anyone have anything negative to say about the DHP programs at all? I know it is the best all around, but are there any downsides to this at all? Is this the 1.0 version that I would be getting from 3800performance or is it the 1.5? If anyone has gotten one of these recently(DHP through 3800performance) please let me know your experiences good, bad, or otherwise. Thanks.
