Turning Up The Boost On My 7M Supra - The Right Way.

In this video, I install a 3-port MAC valve boost controller and turn up the boost on my mostly stock 7M-GTE-powered Toyota Supra the right way. No manual boost tees, no guesswork — just clean, controlled boost using ECU-based control.

You'll see the full install process, my ECU Master setup, and some driving clips showing how much better the car responds after a proper boost controller install.

Whether you’re building your first turbo car, tuning a 7M Supra, or just curious how a MAC valve changes the driving experience — this video breaks it down.

Parts Used:
– MAC 3-Port Boost Control Solenoid
– Custom wiring to ECU Master Classic
– Factory CT26 turbo on a stock 7M-GTE

Topics Covered:
– Boost control setup with a MAC valve
– 7M-GTE tuning tips
