Dyno tuning maps?
I am in the process of having my car tuned on the dyno with my new engine. The guy doing the tuning does a ton of late model stuff but not alot of OBD1 stuff. The car is running good and making around 430 whp as of right now. He has the timing down to 24 at WOT. We both believe there is a ton more power in this thing. It has been a work in process and its going quite slow. I am looking for some timing maps from people who have similar setups so we can see where they are at. I know alot of you guys have been tuning your cars for years on end and you probably have it nailed down to the T . I would REALLY appreciate some help guys. I am hoping to get this car off the dyno and on the road soon. Mods are as follows
All forged 383 stroker
Afr 210 comp port heads
Jessel 1.6 shaft mount rockers
P600B procharger and intercooler
Lt4 intake.
58 mm bbk throttle body
60 lb injectors, aeromotive stealth pump and regulator
1 7/8 ARH step headers with 3" Magnaflow exhaust no cats
comp 280 xfi Hr-19 cam
Ltcc conversion
centerforce clutch and findenza aluminum flywheel
and all the other goodies that go with it.

I am at about 530rwhp with a similar combination. No info on CR and boost number but I think you should be able to surpass my numbers.
I have CR 9:1 and wOT spark advance at 19 degrees with water/ethanol injection (no IC). Have a look at Dizwiz24 threads; tweaking spark advance not only at WOT may also result in some nice gains.

You're not making enough power to be outflowing the blower or falling off of the compressor map yet. I have to think that you are under-pullied or have some belt slip issues.
What size blower pulley?
With the low 3.05:1 step up ratio of the P600B, blower you will want a relatively small blower pulley. 2.95" or even smaller.
For reference: my little Powerdyne (also with 3.05:1 step-up ratio) makes ~9.5 psi (also intercooled) at the manifold with a 3.12" pulley at approx. 6500 rpm.
You should be able to pulley for more boost and more power, if you can avoid belt slip.

Whats the air fuel?
On 7 psi with those heads i would feel good with 26-27 deg, on 5-7 psi. I ran 23 deg on 8 psi but felt it could handle abit more but i never really tuned it there, as i spend more time at 12-15 psi. I am turbo and at 9:1 comp tho
High 11's to 1 air fuel and a 2-4 deg increase will boost power.

I have a 2.95 on it now. I am going down to a 2.67 or a 2.55 soon. I will probably go with a 2.67 6 rib until greg @ blowerworks can complete a 8 rib bracket assembly for me. I have zero belt slip on it as of now. we messured it on the dyno. The car is making 7.3 psi at 6500 rpms and only putting down 448 whp. I think with a slight pulley change and some meth I will make over 500 whp.

I am making the following boost curve (I have afr195 Heads comp port elim, no intercooler).
2.75" pulley and gregs 8 Rib dedicated drive.
3000..5Psi
4000. 7.5 psi
5000. 10 psi
6000. 12.5 psi
Thats in summer temps

I reclocked the p600b and got the right angle for it to fit into the throttle body.
I got the silicone coupler sleeves from greg. greg has helped me out a lot
