My Dyno Numbers, P600B w/HCI

Just got my car dyno tuned at Alternative Auto. Lidio hooked me up and made me a custom chip. I made more power than I thought I would . Here's the results:
- 450 RWHP @ 5600 RPM
- 440 RWTQ @ 4500 RPM
- 12 Lbs of boost @ 5600 RPM
- 11.5:1 AF ratio

Setup:
-rebuilt stock 89 shortblock: arp studed mains, speedpro rings
-ATI P600B Procharger with 3 core Intercooler, 17lbs pulley
-new edelbrock performer 5.0 heads 1.90/1.60
-Trickflow Street heat intake, 70mm TB
-F303 cam with 1.72 Rockers
-75mm Prom cal'd to 36 Lbrs, dual walbro 255lph's
-full exhaust

I will post up some dyno sheets once I get them on my computer..
what do you guys think? Is this pretty good power for this combo?
