I know they're bigger/better than the s4 wastegates... but how much control will i have of my boost if i get a racingbeat downpipe/presilencer and a dynomax cat back? I will have my FCD working.

Thanks

u will spike to 10+ psi

For the love of all thats holy don't install an FCD without upgraded fuel and at the very least an accurate a/f guage. If you blow a vac line on the waste-gate actuator you'll destroy your turbo and probably your engine.

1. A/F gauge? That's what you're reccomending as a mod?
2. If i pop the wastegate actuator line off, i will notice the boost spike, as i watch the gauge constantly, and i will insantly let off. Your argument isnt valid. The vacuum line off the wastegate actuator can pop off any car, not just a modified one.
3. Why would it destroy the turbo from one run at 20 psi?

An Air/fuel gauge is about as usefull as the stock boost gauge...they arent.... Do not rely on the stock boost gague and especially do not rely on an air fuel gauge...If anything get an EGT gauge or a Wideband O2 and especially a real boost gauge.
