As seen on the other fitech thread, for the ga-billion-zillionth time...an oem distributor is not worth farting around with, as you will have nothing but issues, become frustrated with the system, and ultimately end up buying a pro-billet anways. We have sold probably 2500-3000 of these since inception. I have had like 3 guys ever luck out and get one to work with an oem Distributor, and that's WITHOUT timing control even. asking for trouble.
