Having inlets that flow better than the stock ones lets you run a little more boost up top without having wastegate DC going through the roof (easier on the turbos).
Most of us can run 20-21psi in the midrange however the stock inlets start to choke the turbos and boost can creep away from your target above 5500rpm. |

You're asking this question when you just ordered and paid for inlets? LOL

What is the DC bit? (I get the wastegate bit) Haha yeah.. I wanted to truly understand the mechanics of it. I understand that it has gains but not exactly how it works lol. I know it has gains, but how does it work? lol not so sure. |

FYI if anyone is interested.. I asked Tony and this is his reply:
Question: Apart from the obvious benefit of more air flow, what other benefits would your Inlets have for a stock turbo setup? Answer: That is it, they allow more air flow which in turn allows you to run higher boost with less WGDC. This will allow you to make more power. (Virtually exactly what jb4-335 said) |

From memory when I had stock turbos I was running about 18psi at redline but for the longevity of your turbos that's probably not the best idea. DC is dutycycle. Basically how hard the wastegates are working (closing) in an attempt to hold the boost at the target level. The lower the wastegate DC the better it is for your turbos.

What tune were you running? Was it the procede v3 or something else? I checked your build thread. |

I was and am still running a Procede V3. Old school lol
I'll probably change it to a JB4 soon once I get my inlets. The only reason why I'd do that though is because the JB4 with the right firmware can run any PSI. The procede has a 20psi cap which sucks balls. Otherwise it's a really good tuning tool once you get the hang of it. I'm on RBs so will be pushing them to 24+ psi most likely.

you need the harness from BMS, and the standard N20 tmap part number specified (13627843531) |
