Here is some info:
Stiegemeier Throttle Body and Plenum Porting
Not only can we port and modify your current TB&PL, we also carry the full line of Dragon® throttle bodies and plenums.
Throttle body and plenum modifications should not be taken lightly. Air flow restriction in this area will limit HP potential. Stiegemeier offers port-matching to fully welded and enlarged plenums to deliver all the CFM your throttle body has to offer.
Please Note: OEM throttle bodies have the best driveability! After-market single-blade types will almost always improve HP and TQ but usually demand attention from an experienced tuner.

Bench flow data was measured @ 10" of pressure, final numbers were converted to 28" data via pressure conversion constant of 1.67.
Example of converting 10" data into 28" data: (593.5 cfm x 1.67) = 991 cfm
