I bought the Hass 380-410 injectors from Web 3.0 a little while ago and decided to get them cleaned and flow tested after it was suggested to me by aaronjb.

It’s a good thing I had them tested too. I wouldn’t have had the right sizing to factor into my PFC if I didn’t. Here’s the results:

Before Cleaning:
335, 335, 335, 342

After Cleaning:
340, 340, 345, 345

test pressure was 43.5psi
performed at 0.775 specific gravity at 5000rpm with 6.0ms pulse width.

I don’t blame Web 3.0. I’m sure that’s how the injectors were sold to him with a the hass kit or whatever and he was just passing the info along. That’s my assumption anyway.

My reason for posting this is to caution anyone doing any specific tuning with these injectors and sizing them in a PFC...

This was something I wanted to do, but kept putting it off for a while as I wasn’t quite sure that I knew everything that I needed to know for the install. The biggest thing here is fear of the unknown. It’s not that hard to do, but it is scary to cut your wiring harness. At least it was for me. It is important to note that the LC-1 can be installed in different places. My information here is for installing it in stock O2 Sensor location 1 (Passenger side in header). The wiring will be a little different if you install into location 2 or if you have the bung installed and put it there.

I got the majority of my info from reading posts on the board from people like Tem. I got even more information from beanie and rando...
