got my single turbo done and firein her up today but the car cuts out at 2500 rpm, the duty cycles reading 10.2 on the commander as soon as it cuts out. i have 550 prim. and 1600 sec. and supra pump. the motor has just been rebuilt with a street port, so its a fresh start up. any ideas i wanna see it i can play with it more tonight.

 

Since the motor was pulled out, rebuilt, reinstalled with a new single turbo kit, this means everything is suspect in the fuel, ignition, and engine control systems.

You will have to verify the functionality of all of it.
