I would suggest the GTRS, you could get 250whp on pump gas even with the stock manifold.
I would suggest a Unitronics tune and you can get that along with injectors and the Elim kit as a package.

So assuming i get this package you outlined, and the custom manifold, i plan on getting a high flow cat and a high flow muffler, and of course FMIC, with the tune to work with 93 gas from sunnoco, how much whp you think i should be getting? and torque? i have the ATW as well..........

dammit mike, you just made me *** on myself.......now i gotta deliberate whether i should wait for the spring or just get it now........my four ringed hood is looking at me right now saying: "wtf r you waiting for??" LOLOL
Anyways, how does the chip tuning work with you guys? we have to send the ecu in and wait for it with the rest of the package?

if not, i might end up breaking out the credit card
Custom K04K04
Only way anyone is going to pull 230hp out of a K03 is on race gas and believe me I know seeing that I pretty much have the record on highest hp K03 for the A4 1.8t and that was done on my 2000 ATW. lol
I made about 250hp on 104 octane pushing 20psi with a custom GIAC tune. Funny thing is that was done on the stock injectors and stock 4 bar fpr. Like I said, there is no reason for larger injectors for a K03 on the B5 cars and this is because the B5 has a rising rate FPR while the B6 cars have a static FPR. So the B6 cars need to go larger injectors when the tuners push the boost higher then normal, this is why the tuners offer a stage 1+ (injector) tune for the B6.
Never got a chance to dyno my custom street chip for 91 octane and pushed 26psi, but dont think it was anywhere near 230hp.

I have a custom built "K04" from turboconcepts (wheels below, machined/optimized housing), running on stock injectors and what is called a "TAP Stage 2 12.5psi +50HP" chip/tune (FMIC, Carbonio, Test Pipe, Miltek). Turboconcept (sales@turboconcepts.com) used my core; price $200 or so more than 'as new' rebuilt (virtually new turbo).
My boost curve goes to 18.5 psi at 4000 RPM (10 psi at 2000, 10 psi at 6500). No codes (lean or else). What power can be expected from this setup?
Still trying to get a tune that works with this setup (plus injectors and AFPR 3-5 bar standing by).
K04 – optimized by TurboConcepts
COMPRESSOR WHEEL
Inducer: 41.0 mm
Exducer: 54.0 mm
Tip height: 5.6 mm
Blades: 6 double,staged, extended tip
TURBINE WHEEL
Inducer: 44.5 mm
Exducer: 40.44 mm
Blades: 12
10 degree clip
Compressor housing shape-matched to larger compressor wheel and blade shape.
Compressor outlet flow optimized.
Turbine inlet flow optimized.
Calibrated waste gate actuator.
Characteristic:
-Turbine modified for faster spool up and increased flow to work/benefit from high flow exhaust system
-Compressor modified to generate early boost, increased midrange power and high flow at high RPM
