Re: how much power will i gain.... (blackonblackLT1)
a grand total of 0hp
58mm is worthless on a 350 TPI
Removing your current MAF for a new one is pointless unless yours is broken. But removing the screens in your current MAF is a good idea and might yield a few hp.

What he said...58 would only do something if you had new heads, cam and headers, somethin thats gunna need alot more air flow.

install 58" throttle body
You'd probably see quite a power loss if you installed a 58 inch throttle body, since you'd need to remove the hood and the almost 5 foot-wide throttle body would give you too much air drag (j/k). :D :D :D
Actually, unless you have modified the cams, heads, and headers, your car won't need so much air that even a 52-mm throttle body can provide. Other bottlenecks are limiting your power, not the throttle body.
