Very good write up.
Very informative for those of us that do not have any of these products being talked about.
If I can afford it, I would LOVE to go with the DSE stuff. A friend of mine went to SEMA this year and said that their stuff is nothing but TOP-NOTCH!!
But, for my personal use of the car, which isn't going to be used on the track, just a "once-in-a-while" weekend warrior, I may go with the Speed Tech instead to allow more money for other aspects of the build, et: big block power?
