To be honest i dont see any real differences between either product. Many people are getting positive results with both softwares, but I do understand how Ecutek would be pissed at the movement (maybe a certain company). It all boils down to choice, there are people like myself and platinm that like the pice of mind of having a 'pro' tuner workin on our cars. Its the same thing as people who pay for a brand name exhuast (HKs Greddy etc.) and those who choose to have one made at a muffler shop. As far as im concerned ill stick with SS, but more power to Snowman for leading the way on the open source tuning in Tampa Bay. Do whatever you guys feel comofortable with.
