Just Cam HP Gain
I will be having MTI install a Stealth II cam with new push rods, lifters etc. I have a 2000 A4 Vert with 3:15s, Kooks headers, Kooks X-pipe, high flow cats, Blackwing, Yank 3000 and TI exhaust.
What do you think the cam will add for HP after dyno tune?
Is it worth it to add the U/D pulley?
What should I expect total HP at the wheels to be?

Easily 25rwhp, maybe 30, and trust me a cam on stock heads will pep the car up a bit. If you do this, I recommend upgraded the pushrods, springs, timing chain, pulley and retainers. A cam of this size will wear those springs out over time, much more quickier than a stock cam.
Have fun with this and trust me, the cam makes a noticeable difference.

What degree on the cam? .5XX?

yeah that def. seems a little low. just header guys with no tunes are running 330-340rwhp. with a big cam like that, and a tune, you should be well over 350. id say closer to 380ish. tune makes a big difference though!

I forgot the YankSS3600 converter... got that too, could that be a reason for low numbers? He also said something about a clutch pack in my A4 maybe being bad. Still, I think crappy tune. Car runs fine though... maybe I'll get it retuned by someone else since I have moved since then. intake .591 exhaust .595 112 +4. You guys think I would benefit from a new tune? The company that did the work has since gone out of business... havent heard to many good things about them.
Max rwhp 350.4 @ about 6800 rpm
Max TQ 363.3 @ about 4100 rpm
Graph looks strange to me.
