So is this because the stock cam and crank sensors don't put out a square wave, and the DIS converts their signal into one?
There are no mod kits needed with ms3. The map sensor is built in up to 21 psi and you can upgrade to the mapdaddy for up to 44 psi. The wbo2 is just plug and play. Tuning the car is really easy and I have a "starter tune" for anyone intersted that has the correct calls and good tables in it. I have patience but time for me is slim. Im hoping once im done moving next week I can start a build thread for ms3.
