⛔️⛔️⛔️⛔️DIVERTER DELETE⛔️⛔️⛔️⛔️⛔️
Want to point out to guys that you must not replace the LEYO BOV valve supplied with a TTE525R. The TTE525R is designed only to work correctly with a valve that vents to atmosphere.

Replacing with an original recirculating diverter valve is highly not recommended.
A recirculating valve, stock or aftermarket cannot function at all on a TTE525R due to turbo design changes made by TTE.

TTE delete the diverter port in the compressor cover to give smooth air path for performance advantages. No turbulence, Faster Spool & Engine Response, More Power.
Tip: Red spring supplied with your LEYO valve can help improve torque and power especially in the mid RPM range on certain set-ups. Worth asking or informing your tuner to test
