I don't disagree that a dyno tuned chip is the best way to go but I have yet to hear of an engine blowing up because of a main order chip running lean in the power band.
There's been thousands of chips sold and I haven't heard 1 story in 5 years on these car forums of anyone blowing a motor because of a mail order chip.
Technology in tuning has evolved and tuners have learned a lot. Heck, even SCT now makes trips to shops around the country to educate people on the correct methods of tuning.
The SCT engineer is no hack either. He use to work for Ford from what I've read about him.
If you got the money and time to spend for a chip for a car/engine with bolt on's, have at it.
The majority of the people who buy chips just have bolt-ons and never even get to head jobs(no pun intended), all-motor build up or induction.
When you get those kinds of mods, you better be getting the engine tuned or you are asking for trouble.
