1-Does anyone knows about the stock boost in gen4 by ct20 ????

2-as you know the fuel-cut will take place in 18psi in gen4, how could we fool the original ECU to prevent the fuel-cut , (i will install manual boost controller) ?
please help me , some SR20det engine in a 900kg car has bit me up

the power was around 250HP , i need around 335HP !!!

The st215 engine uses a ct15b, not a ct20b. And someone recently dyno'd at wastegate pressure of 9psi.

The same way you do it on a gen3, build a map/voltage clamp.
