I cant seem to get past 3lbs on just the wg, if I uninstall the hose to wg it builds nicely, or if I put a T in between the lines same thing builds up. The springs in suppose to be .5 bar. I checked all hoses, and everything seems fine. I run the hose from the bottom nipple of the wg to the compressor housing nipple.(is this right?)

 

bump

 

seem like you having the same problem as jdmh22hatch on here

 

But unlike him when I pull the WG line off it keeps on building boost.

 

someone???

 

Umm if you unbolt the wastegate and it works. Its your wastagate. Get a new one and make sure its sealed probably. End of problem.

 

wat kind of wastegate is it, i would get a 38mm tial they are very acurate. also were do u have the vacume line to, u may not have a strong enough vacume, t off the brake booster line and it should work if your wastegate is good.

 

Its a 40mm Tial, I have the line going from the wg to the turbo comp. housing.
