Man there's alot of great info on this site already
i've just thought of a question that i haven't seen posted yet. Maybe someone can give me some numbers on the difference in hp/torque #'s between an 87 perf and 91 perf? Is there like a 10 horse/30 torque difference between them, or is it smaller. I was looking at Bill's dyno chart on the 09's and noticed a 50? torque difference between the stock truck and the perf tune....that's a helluva gain. Just trying to get some info in order to justify getting a 91 perf tune. I don't expect a mileage increase..altho some say they get better mileage on the good stuff. Thanx for any replies. You guys rock.
