is 21 pound spike holding 19 psi too much for K03s? i dont no if its the warm weather or my new turbobackor what but my boost has gone up about 3.5-4 pounds? and i dont want to rush blowing my k03s just yet.

 

it is probably the turboback. The added psi will have an effect on turbo life, but it shouldnt matter that much

 

I would run some vag-com logs on block 115, something is not right, you should not be boosting that high.
Yes, you are over spooling the Turbo's & they will not last long. Your exhaust should have nothing to do with boost.

My guess is you have a N75 problem, or something wrong with the wastegates.

 

if there is somthing wrong with the n75 valve would it show up on a regular scanner or no?

 

well, a full turboback does help spooling, and if the cats were bad enough it could raise boost pressure. then again, i dont think it could raise it that much.

 

i dont have cats anyway im thinking i might just do a mbc to be safe

 

No cats has nothing to due with it. You still need to set up a MBC, it's only going to be a band aid on the real problem.

 

maybe ill try the n75 valve? what could have gone wrong with the wastegates?

 

There might be a leak in the lines, or the accualtores are sticking.

 

are my wastegates internal?
