porting stock meter?

Personally I think it's bad idea...too many people have had drivability issues by doing this...to me it's not worth the 3-5hp gain...

IMRC deletes help with top end HP but there's noticable low end power loss...My tune and Long tubes helped get that back along with my custom intake...I wouldn't recomend them for a car without a supercharger or ported intake or heads...

As for the MAF, if that center post wasn't needed Ford probalby wouldn't have put it there...I know a few guys in our local club that have removed the post and smoothed out the rest and their car never ran right again until they got a different MAF...the aftermarket MAF's are designed to work without that...If you look at a Pro-M like I have it has a completely different sample tube than what the stock MAF has...
