Ok. I'm looking to put a chip in my 89 GT and I've been searching on the forums about the probinator chip and I've heard good things and bad things about it. I've heard that it good for only bigger turbos because of the advance timing programmed and I've heard some people saying that it runs fine with the stock turbo.
So I want to know if I should invest in a probinator chip for the stock turbo or go with another one like Zombie or adam chip. And do any of these chips are still sold? Cause if so. I'm having a hard time trying to find out who sells them.
