the injectors can handle more hp than stock, i think they only run at 80% width from the factory, so ur computer should sense ur running slightly lean and compensate for it. heck, on the zetec, the 19 lb/hr injectors can run 160 whp just fine!! so just cams on a dura shouldn't mean getting new injectors. if you do a full out na build, then i can see a problem, but just cams shouldn't need a tune. if you go w/ a sct or something, then you could have issues from an emmissions standpoint

i would only recommend stage 1's if your gonna try and still pass emissions, the stock parameters of the PCM should still allow enough compensation for the stage 1's

Stage 2 will be fine as long as you dont remove the manicat. You can put the tune back to stock and they will not find out.

^ that's what i waiting to hear. i didn't know if stage 2 cams would pass smog with a factory tune. i can put the factory tune back, put the big fat factory intake back, i can even put the exhaust back. but i didn't want to have to take the cams back out, lol

There are enough cats there to take away any extra emmisions that the cams give if any.

The emmission police cannot tell you have a tune in your car or cams unless there wild so the cam and a proper tune sold pass , I can get cams ,turbo etc to pass the sniff test here in NC

no it isn't in that respect, i think he's just referring to tuners in general

you'll be fine in the visual department
