<center><img src="http://pictureposter.audiworld.com/39497/stage3vs.jpg"></center><p>pretty happy with an 86 HP gain to the wheels and almost 96 in torque vs. the stage 3- setup. Both runs were with 100oct in the tank, but the stage 3- run was with a 91 octane program whereas the full stage 3 is on code for 100.
Looks like my A/F ratio is a bit richer too.
Overall I'm pretty stoked with it (although it would have been nice to pull higher #'s than Swift ;-), I hope putting the 91 octane stage 3 software in doesn't disappoint me after running around on 100 for the past week...and after seeing how hot the engine gets on that dyno, I'm thinking intercooler misters of some variety may have to be next.

yeah, same dyno, same exhaust / cats, etc. only changes were the EVO intake, RS4 MAF, injectors and
software...and the upper intake pipe/hoses/etc. for the rest of intake tract but unless that CF Y-pipe gives me bling-bling HP those are the only power increases to the car.

Not 100% sure vs. my 3-, but here are boost graphs from 2+ to 3. S4irish took the first set of logs
about a year ago, I took the stage 3 ones a couple nights ago. I ran the K04's on that same software for a couple weeks before swapping to their 3- specific software and it didn't boost any more, it just held steady to redline instead of tapering off like that so I would guesstimate 12 psi or so.
If someone wants to school me on how to do the PSI conversion from mBar, I could convert the stage 3 graph.
Stage 2+

subtract your atmospheric pressure (whatever your mbar is at idle) from all the #s, then....
divide by 1,000, and finally multiply by 14.7
For example, here in MI atmospheric pressure is around 980 mbar. Therefore, 1980 mbar - 980 mbar = 1,000 mbar of actual boost. 1,000 mbar / 1,000 = 1 bar of boost. 1 bar=14.7 psi
