Fuel Pressure with 560's?

[EagleTalonTim]

I just did some 2nd gear pulls in my Auto TSI and saw that I start getting knock at higher RPM's even though I have a rewired 255 installed. I currently have the base fuel pressure set at 38psi. Should I go higher? Is .28 gap on NGK BPR6ES too small to raise the boost to 18 psi? I am currently running 16psi. Profile has all mods listed

EVO's run 43.5 psi base fuel pressure, I'd start there. Post a log...

You should get a wideband and see what AFR you're really running. You may be getting rich knock.

I believe you meant .028 instead of .28. And .028 is the recommended gap and no it won't be too close. As you go up in boost you should close the gap up if anything to prevent spark blow out. I still believe your problem is with timing as to why you are knocking. When you start running out of fuel your injector idc's will go up.

install w/b before turning up fuel pressure,if you dont know dont start guessing....bad things happen
that way.

I'd just keep one thread going on your problems, or you'll just be asking for a headache
