What so you guys think about these numbers PRC 2.5 heads and custom cam?
Here are the detail on what the car has.
a4 with a Circle D 4c 3800-4000 converter. Custom ground Predator Z speced cam 230/230 598/612 111+2, Prc stage 2.5 5.3 heads, Unported fast 92/ Jantzer 92mm throttle body, 25% under drive pulley, Pacesetter longtubes, TSP catted y pipe, LM1 catback. I do not have a cut out in the cat back so this is through the full exhaust and catts. The car also has a 85mm TSP lid and 85mm z06 mass air.
The car made 422 rwhp and 396 tq on a dyno jet with the converter locked. It made 401 and 378 unlocked. I think the air/fuel was around 12.3. The numbers look ok for an auto car what do you guys think?

are you talking about numbers before the heads cam and intake? The car made 320 rwhp before the heads cam and intake. So it basicly gained 114 rwhp from the heads cam and fast 92/92. I think there might be a little more in it because I don'tthink the yhave the tune completely dialed in on it. I am seriously thinking about getting rid of the cats and adding a cut out to see what it gains.

Regardless I'd be happy with anything over 400rwhp in a stalled auto

I am pretty sure thats already corrected. My old stalled heads and cam cars made 396 to the wheels and would run 11.30-11.40s on street tires when the track was preped good with a high 1.7 60 ft and this car definetly feels a little stronger. Both cars have pretty much the same converter also.

Basically on this day your car is making more than the dyno is showing you.
