My friend has a greddy turbo timer which he will sell to me for very cheap. He had it in his MR2 for a few months, so it has been used. The question is, should I buy it or not. I have been searching aroudn the forums some and found that there have been problems with some tts, is Greddy one of them? And is it a bad idea to buy a used tt? Will I run into any additional install problems with the Greddy as opposed to any other tts?
