today my boost started to act up, it holds up to 5 pounds then it starts to sputter like the dv is open u can hear the air escaping the car runs fine otherwise, no cel it could be a loose vac hose or somthin i couldnt see cause it was dark but i will check it out tomorrow, i really hope it is a vac hose cause it is a easy fix

 

Check the hose that runs to the top of the DV. Check all the hoses, and it also maybe the n75 valve.

 

i just put the valve on a few days ago

 

Any crack in the plastic? Once you have it straightened out let me know how the N75 works.

My car is a bit "peaky" with my chip, followed by a flat spot when im sure the watstegate opens.
