So I just recently got some things installed in my car (systemax intake mani, 47lb injectors, 340lph fuel pump) and a dyno tune. So my question is if I install a afm power pipe (i have a bbk cold air right now) and/or a bigger 75mm TB (I have a bbk 70mm right now) will I have to get it tuned again???

it will throw your air/fuel ratio off by how much i dont know but it will change things for sure....i say retune better safe then sorry

Ok. Damit! What about just the afm pipe?

to my knowledge any change can be harmful to the motor if your racing it once its been tuned and u change something......if u are not ripping on the throttle or swinging donuts it wont kill it as i drove around without ripping on the throttle in my stang with a blower and no tune for a few weeks

Normal driving should be just fine, your 02 sensors will take care of that. You personally may not even notice a difference during a WOT pull. But because you made changes after the tune, you should at least throw it on a dyno and check where your air/fuel is at.

Ok guys thx so much for all the info!!! Looks like I'll have to wait until I get a turbo or sc to dyno it again

when your talking about 800 hp you should just burn a custom chip

most guys here can give advice to about the limits of a blown stroker, and no more than 500 or so hp

your in BIG BOY territory

47lbs injectors on a na build? what u got a monster motor or preparing for some type of forced induction. id put some smaller injectors in it until your blown.
