As above I'm running a simtek ecu, with a RCM induction kit with the trumpet that bolts to the MAF. What are my options to get rid of the MAF? I've seen a blanking plug/bung from Cobb and Grimspeed that bolt into place in the original housing, but these are or new age cars. Would these still be compatable with my version 5 STI? What are other people doing?

Cheers

 

You can get a trumpet that bypass the MAF from RCM or Graham Goode
