I went from DD TTPM to Edge Comp
I had a DD TTPM for about 8 months, then when the Edge Comp came out, I upgraded to that, so I have experience with both products.
All other BOMBs in mi sig were on the truck with both TTPM and Comp, so I think I have a fairly good comparrison.
As has been stated already, the DD version of Edge's boxes are toned down slightly on the timing, and are supposed to be optimized for DD injectors. I did notice my engine seemd to run ever so slightly smoother or evenly with the TTPM. I thought I noticed a slightly more aggressive, or "radical" sound when I installed my Comp, but it was only an audible difference. You will absolutely be happy either way, in my opinion.
