I think the MS3PRO the non science project, fully assembled ECU is quickly catching on. It has phone support, training classes, etc that the "science project" grade makes you do a little more leg work for.

Lots of Drag Week class winners have been science Project MS cars over the years as well as lots of land speed stuff.

In MY scenario I saw the Holley stuff in Action on roadkill when they did the engine and EFI swap in the middle of PRI. I thought it was cool and I wanted it, then I looked at the price once you buy all the stuff to make it work and I pooped a little. That's when I started to dig around on the MS stuff and I am glad I did. I learned a lot doing it the "hard" way and I saved a ton of cash.

I sound like a salesman for MS3 but I am just happy with my experience.
