Lowering Boost, does the fuel amount change

[chrismitsu47]

I have decided after getting my new GS-T that my 24 pounds on a e3-16g is just more than I need on the street. Can I set the boost to the stock wastegate setting without changing anything and be able to do WOT pulls, or would I have to change some of the fuel settings in my DSMlink.

I believe that you can keep your current tune. Boost is relative to the amount of fuel pressure that you will see. It will increase 1:1, for every pound of boost you add your regulator will add a pound of fuel pressure.

Yes you can it won't hurt anything. But instead of turning your boost down you can just keep your foot out of it and still save gas. That way if you do need that extra power for some mysterious reason besides street racing you don't have to change your boost settings.

True, but for someone my age it's not the best idea to be running 23 pounds on a EVO 3 16g on the street. I like the power of it and all but the boost goes from about 7 pounds and just spikes up to 23 and holds and if I do use the power it just spins the tires and blows an intercooler coupler off, so I was just thinking of lowering it for the better drivability. And I dont like to street race just because the first moving violation that I get, I get my license suspended so it's not something I do. I plan on only using it on the track.

You should be fine, i keep the Blitz at 10psi til i have a reason to turn the magic knob.

The amount of fuel injected goes by how much air is going in, so lower boost = less air == less fuel. No fueling changes should be necessary.
