Now the bost controller part
First i took the boost reading with stock cinfiguration using a normal pressure gauge
It was getting maxed out at 6 psi whereas it should max out at 9 psi for this engine. This means that either wastegate is opening up early or there is something else wrong. Boost controller is installed between the pressure feed to the waste gate actuator from where u can control the threshhold of pressure at which waste gate opens up.
I was a noob at this as well, ghuncha guided me over the phone at many points
First job was to find the wastegate as engine is tilted and fitted under driver and passenger seats, it was not as easy as it is in other cars.
I took out the seats, engine covers and everything else, but it was still not acessible.
So i went under the van, took two shield, one metal, one plastic and then i saw the required compnents. Also i realised at that point that taking out the engine covers and seats was not needed at all so everything inside the cabin was put back in place
