410-430 RWHP done right.

 

also forgot:

TB Bypass
and im sure a few more things too

 

are you m6 or A4 you also will need gears 3.73 for a4 and a stall for a4. 4.10s for m6. also those injectors are big for an n/a 355 36# would be better

 

its an M6 with a strange 12 bolt with 4.10 posi

 

Should be pretty awesome. Those injectors are fine since I'm sure you're going to get a good tune and they'll just run at a lower duty cycle than smaller injectors.

390-420 rwhp if everything is running right and depending on the dyno/weather. Track times are a better measure, and you should be in the mid-11's with that rear and the M6.
