18 + psi, no no no no!!!!
 

I have a new problem, looks like my 8psi internal wastegate doesn't works correctly. When i hit full boost in 3rd gear it goes to 18 + psi, like if the wastegate doesn't open.

I check the wastegate arm to verify it moves, and seems to be ok.

Need to change the wastegate or what i need to do? :3

you sure the vac line didnt pop off?

Re: 18 + psi, no no no no!!!!
 

either that or the line is getting weak from heat causing the line to expand giving your WG a false psi reading and making it open waaaaaayyy to late. It was happening to me. I had to re-route my WG line behind the VC...

I think that is going to be the problem.

Let me change it, and see what happens.

Thanks

high pressure fuel line is nice to use for vac line that is under high heat and pressure ;)

Internal wastegate changed, same problem, vacuum line changed, same problem.

Solution: Need an external wastegate

Lets see your down pipe. You sure the flapper is opening all the way?

You might have a leaky diphram or bad vacuume source. make sure you dont have a check valve or something from where your getting it from.
