I made 26lbs with my 21cm, on stock sticks and a fuel screw in far enough to push itself around! Oh and a heavily ground fuel pin too.

 

You don't have a 21 cm turbine housing.

 

With the mods in my sig, my truck runs about 39lbs until I run out of gear (about 65mph's). Then it drops off and holds about 31lbs screaming it's head off. I don't know much about any other injectors, but when I put the POD's in it made the biggest difference. I don't really care for the idle haze, but I did gain mpg's and quite a bit of power for $200 (got them used). Another thing that gained some PSI was the cannon of an air intake I made.

 

Didn't you put a HX35 on?

With my stock injectors turned up I and around 22psi with both an 18.5 and a 16cm housing with the A518 and the 47RH I put in.

Changed to POD's and the boost jumped to 30 something. Went to a WH1C with a 12 waste gated, set at 38psi, then to a HTT stage IV compressor again gated at 38psi.

Changed to a S300 62/65/12, gate is factory set at 40psi and I was pushing about 38-39psi.

Went to EDM's 6x16's. Now with a PS intercooler and 3" tubes I'm pushing 45ish for boost.

 

still didnt rebuild it yet...soon though
