tuners are a get what you pay for item. to get more out of your tuner you have to pay. i bought my sct from morepowertuning on ebay and they build custom tunes according to your needs. you fill out the form and they build the tunes.
tuner and programmer are the same thing. a chip on the other hand installs inside your pcm and then requires proper tuning. the programmer term basically came out with preloaded software that flashed your computer then as it allow you to manually adjust features the term tuner followed but still the same aspect
