dont know where a stock dyno sheet would be or havent found one yet, you can go on youtube and see some stock cavalier runs on the dyno though im pretty sure they show the dyno chart
just go to youtube and type in ecotec dyno, there a blue one on there I actually just watched it again and realized it not stock but not far from stock. it just had a 2.5 exhaust ,4-2-1 header, aem intake and Hp tuners and got 161 hp, im pretty positive the stock eco's are rated at 140 hp, if ya want the have a nice spec sheet at chevrolet.com
I'll have one SOON.
