How come I never hear anything about upgraded fuel pumps in Audis?

The stock fuel pump is good for around 400 hp
The K04 kits run a 5 bar to raise fuel pressure but the stock pump will deliver enough fuel to keep up with the demand.
A few of us are running Walbro 255 high flow fuel pumps.

Re: Just a fyi there is 2 versions....
a regular 255lph unit and then there is a high pressure version.
A lot of people when they buy the pump just look for the cheapest one which is not the high pressure version which is prolly $15-25 less.
Are you running a kit or did you make it fit cause the walboro is physically skinnier. The ATP kit uses the high pressure version and is the same pump I made 400awhp I believe either at 3 or 4 bar of fuel pressure.

At 20psi of boost I made 385 whp running right around 3 bar at the fpr, this was on a mustang dyno. I should be running on a dyno jet very soon.
