would it give me anymore power or able me to run a little higher psi or what if i had a star stage 1?what will they do for my performance

with a stage 1 don't even think about it. You will already be running rich as it is. there is no need for bigger injectors.

-97 GS (First project, 299 whp)(sold)
- 97 RS 2.6 last numbers: 306hp, 352tq @16psi (Dead, parted out)
- 99 GS OZ, Hahn Kit, 56k miles (Sold)

- 02 Audi A4 1.8T Quattro

ok thankx what about stage 2 what are the benifits for that?

benefits @ stage 1 and 2 arent so much being able to run more boost, but not having to run ridiculous fuel pressure. stage 1 and 2 have to run 90-115 psi fuel pressure to have the stock injectors keep up with fuel needs, those fuel pressures are crazy. with a set of 315s, you only need 55-65 psi fp @ 7-9lbs of boost.

for example, was @ the dyno this sat, and at 9.5lbs of boost and 62psi of fuel pressure, i was running ridiculously rich: my a/f was off the chart, lol, and the chart goes to 10:1, i was prolly running like 9 to 9.5:1 a/f, so even w/ just 62psi of fp, i still have a LOT of fuel to pull out.

my fuel setup is walbro 255lph hp pump, SFMU, and 30lb injectors... i REALLY need a SAFC
