Hi all....

Just purchased an MRT Vent To Atmosphere (mach 2) Valve. After speaking to the guy at jap innovations, he tells me its the rite valve 4 my STi 8...... & i wont have problems with fueling etc, & will sound great.

He seemed 2 no what he was talking about! what do u think, whats MRT's reputation if any?

MRT's stuff tends to be pretty well thought of. However, :rolleyes: at anyone suggesting that VTA dumpvalves don't cause fuelling problems when used on the standard (or other MAF based) ECU's. Did he give you this in writing?

Sure, the discrepancy may be low level, and it's probably nothing your engine can't live with, but it's still there...
