1981, 350 Stock engine. Are any of you running the Hypertech Power Chip, Street Runner version, with your still factory setup CCC and ECM? I have one, ran it for a while but did not notice that much difference but now have new engine in so wondering if worth the effort to swap out chips again and see what she'll do now?
Any of you have good or bad words on these chips? Also does the check engine light system still operate correctly with power chip in?
