Boost Leak Checks in MIL?

[So_NAudi]

Ok so long story short i have the idiot light on and the code is such:

P1557
Charge Pressure Contr. Positive Deviation

I started by replacing the n75 Valve, and its still there.

anyone know where in the milwaukee area i can get tested for boost leaks?

Alex,
I've got a pressure tester I made you can use.

Great!

I think thats what i need to do next... I just checked all my hose connections, and they seem solid.

Any other suggestions?

Intake Y-pipe boots, Turbo to IC hoses, ICs to Charge pipe boots, Charge pipes to TB boot, TB boot itself very common, DVs, DV hoses, (being as your a 2000 6spd) F-hose is also common.

yea i was out at brady's dads getting my clear corners done and realizing that ECS sent me the wrong o2 sensor (again... grr...) and he said when i come out with the new o2 he'll pressure test me. he also informed me that the timing belt hadn't been done which the dealer assured me it had been. yaaaaay maintenance costs! maybe one of these days ill get around to doing an actual mod... haha

TB Kit should be next then. 02 is likely the culprit of the other problem as it has some control over your air/fuel ratios.
