Re: new cam,,, runs like crap !
that cam dosnt sound like its to big to screw with the vacum enough to freak the ecm out I start with checking to see if the timing is a tooth off but if it ran good while braking it in you may have broke a spring (you might get luck and spot that with valve cover off) also if you didnt add any thing to the oil for break in you might have flated a lobe
jegs/summit wont tell you if a cam is compatable with your ecm because you can tweak some stuff to make it conpatable but the cam companys will if you take with the tech. dept.
just a heads up just because it sez its works with a computer controled engine dosnt mean it works with all the other stuff you've changed that are compatibal with a comuter controled engine. when I BUILT my engine I started with the idea that if I keep every thing conpatible it will work fine! wrong! what a turd, so after a step learning curv I ended up talking with a guy that could reprogram my ecm.
when I first talked with him he put all my spects in to his computer and with a little math he said I'm leaving 150 to 200 hp on the table cause none of the sensors were in their perameters
lets just say it runs like skulleded dog now
