hi i have an 05 mr and been have some boost problems. I bought the car and i was only getting 5 to 6 pounds of boost. It had a forge wastegate so i replaced it with an oem and got up to 10 to 11 pounds. I have changed all the hoses to silicone and still didnt get back the stock 17 pounds. It also have a bigger intercooler i am thinking maybe thats a reason why. Does anyone have any ideas please help. Any suggestions would help out alot thanks.

tighten all hose clamps. thats your problem.

 

going from the stock ic to a bigger one should only decrease the boost by 1 psi u should probly check all the ic pipeing for boost leaks

 

i got more boost with my full ETS setup.....had to lower the boost until i could log it and street tune.......

 

did check all the pipes more than a few times and tighten them up and same results.

 

i checked for boost leaks a few times and still cant find anything. I have no idea wat to check for next

 

is the turbo directly connected to the wastegate?

 

Do you have the stock bov with stock lines?

 

i dont really know my mechanic disconnected the wastegaste to test it and we were getting full boost. Then we connected it back. I bought a boost controll and still it didnt go up from 10 to 11

 

i changed to the stock bov to the go fast bits stealth. I put the stock one back to see if it was the bov but no improvement

 

Did you put the stock lines back in?

 

i didnt have to change the lines the go fast bits bov is a direct bolt on

 

when you put the MBC in did you cap off the stock boost solenoid??? you need to when you connect the wastegate and j tube to the MBC............

 

krazirob im not that advanced my mechanic is but he is running out of ideas of wat it can be. If u can put in in more simple terms i can explain to my mechanic the ideas. Thanks
