You know I had to make sure I got a DGM one so the tune would go right....
How much difference did the sway make on the STI? Did it roughen up the ride at all?

Both combined stabilize the car much better. It feels much more confident in corners now and sweepers. Didn't really roughen it up much more than it was stock too. Controllable slides in 1st and 2nd gear, haven't gone beyond that yet.

The DGM is definately up at least 15whp lol

Just an update if anyone is following. I had to install a Walbro since the stock pump was proving inadequate towards the top end.

How was the install of the fuel pump. Is it true you have to custom fabricate some sort of cage/shell for the Walbro?

I'm also interested in the experience with the Walbro install.

It's quite simple, I have a HOW-TO on the site here that I'm finishing up this week. No custom building, just a little shaving of the stock housing to get the walbro to fit.

Awesome. Is it true that the 18g is a direct bolt on that shouldn't require new injectors, fuel pump, or aftermarket BPV/BOV?
