Default BMW Early N55 HFS4 v3.1 installation (unfinished)

Hi Richard,

I've emailed you about step two of the installation and haven't heard from you since

Recall: I purchased a new HFS4 v3.1 kit from you, you emailed me the step 1, which is moving those jumper to x2.5 IDC pre scaler. Been emailing you about step 2, which I assume is cutting 3 and jump 2 for MAP sensor(cut 3.5 bar, connect 2.5 bar)?

I have a 2011 335i N55 btw...

Joey

Still haven't got your reply.... I assume you lost me again.

Why don't we talk here? Step one is to set the IDC jumper to x2.5.

Whats next step?

OK, lets start from the beginning so we can do it properly:

1. the power?
2. Tuning box or standard?

1. 2011 BMW 335i with N55 engine, non electronic wastegate

2. Max boost 21 psi (factory 2.5 bar MAP sensor) across the mid range (3000 to 5000 or less), trying to raise it at the redline so I get more "HP" instead of high torque only. still tuning it

3. Tuning box or standard? I'm using Cobb ATR
