you do know that a DIS is a parallel system right? it works WITH the ecu, its not like a blaster coil or any of the old school stuff (6AL etc) here's my opinion:
MSD= the LAST thing you should buy, unless you are running nitrous.
Tune+MSD is better than just a Tune, gains may be minimal, but the features are nice, and i like it. i never did say that it gives my car like a omg50HP or anything but it does help and the car runs very smooth and starts very well. the only downfall, you can hear the thing buzzing when the radio is turned off. that can get annoying.
