LemonA8

Power: 224 kW , 300 HP @ 6,000 rpm; 295 ft lb , 400 Nm @ 3,300 rpm in stock form my A8 made 194 @ the wheels .
Now today running 5.5psi with a good tune ,near perfect air fuel ratio the car made a best off 278 wheel hp.

I've seen 340 horse b6 s4's put about 219 at the wheels so i'm guessing my car is making about 415hp.
"Turbo people" Is the shop doing the tune and they said each Psi of boost is good for about 21-23hp

What are you doing:

1. New injectors? If so, what size?

2. How are you controlling fuel pressure if you changed it at all?

3. What is controlling A/F ratio? What ratio's are you using.

4. MAF, what are you using?

5. Any intercooler? What was ambient temps during testing?

Please let us know.....got any pictures?

and you'll find plenty of hits. Many have tried, but few have succeeded.

an Apexi SAFC NEO was wired into the ECM harness to intercept the mass air flow signal. "Red top" Bosch style Ford injectors rated @ 30lb, and an adjustable fuel pressure regulator.
No chip tuning performed yet, and probably never will since the car put down good numbers with 94 octane

Any applicability to an S8, or only for A8?
