Like Mick said, there is no hard and fast rule on how to tune these cars, And even If you go to a course they wont teach you how to tune, think of it as a liability concern that would hold the host company responsible. Now I cant speak for SCT but Hp has very good customer service and online support with the forum that Luke posted the link for. Yes on the most part HP seems to be dedicated to GM but They are getting there as they dont like to be second best to anyone. The updates come a little slower for Ford due to to their dedication to GM but they are also in the process of adding dodge so that takes man power. I did the beginners course last weekend like I said, it cost $1k fully catered which I thought was ok. But making the contacts and meeting the guys that support the product I value alot higher. And it seems to be a bit of an unwritten law that If you take the time to go to their course they put you to towards the top of the pile when it comes to dealing with customers. Herrod seem to have a monopoly on the SCT stuff, I even asked them if I attended one of their courses prior, could I purchase the software and the answer was still no. That pretty much settled it for me, plus Hp is heaps cheaper and like JVK said the updates are free. The more people jump that jump on board the HP wagon, the more we all benefit, as it adds more weight for them to justify developing the ford stuff further but after dodge is added hopefully the ford updates come thick and fast!!!
