You need some way to read you short term fuel or AFR to realy know.

Never said they wont work or fit just that I wouldn't trust them for too long. My example was to show their craftsmanship or lack there of.

If your going to do it pick up a shop manual or chiltons. Its all layed out in there torque specs and all.

thanks man i appreciate it ill read up more about them b4 i think about installing them.. i found stage 2 crower cams for 40 dollars more then it would be for stage 1 OBX cams

Near as I can tell nobody has answered the question directly.

If you still have a MAF then you don't need to tune it when you change the configuration because the MAF measures the air for you.

If you have switched to SD then you will need to retune because you're calculating the airflow from an extrapolated VE which will be affected by the new cams.
