ported MAF ends worth anything?

i was curious, does porting your MAF ends giv u any power or throttle response? i heard by doing this it tricks the computer or something and it leans out the A/F mixture. but what kinda gains could u see from this?

Thanks,
Ron

Nope. Everyone seems to just leave the maf stock...I did.

leave the stock one alone until you are pushing 500rwhp

Stock tune, on a relatively stock car they can pick up the HP, mostly due to adding more timing.

I ran all my stock internals years with Whisper ported ends.

Once you step up to modified setups. i.e. Head & Cam where you need a complete custom tune it's best to run the stock ends. Mostly because tuners don't have to complete re-write the MAF tables.

Be sure to save your stock ends incase you want to go back in the future.

My car felt like it lost a step with them, so I went back to stock.

just did an experiment tonight at the track with a stock maf screen and all.........and a ported with center bar cutout.

I picked up 1.4 mph and .038 faster consistently on 3 runs. This is on a 400+ rwhp car
same 60' on all three runs, launching at same rpm on an A4 car with yank 3600 tc.
