computer upgrade

I'm new at this mass air flow thing. If I want to change my MAF sensor, throttle body and injectors, fuel pump etc.. To bigger and better, do I need to do anything to my computer? Oh ya, this is on a 91 GT AOD. Thanks.

you probably wont gain any thing by changing just the mass air flow sensor. changing to a larger mass air flow meter is probably what you mean. Be sure the mass air meter's sampeling tube is calibrated to your injector size if it is these mods should not effect the factory program. also you will have to adjust your throttle position sensor. Good luck chris

Thanks Chris,
so tell me, are these things worth the time without new heads?

yes but I would suggest also headers and pulleys along with bumping the timing up to 14deg. Chris
