New Dyno...and I need some A/F help

[Once Bit'en]

Ok got the snake Dynoed yesterday and came up with some good #'s but the A/F is RICH at 4500 to 6000 rpm...

MODS: Bord over .20 block
CAI, AccFab, 2.8 pulley with all 100mm Ids. Napa belt 840
Kook LT with custom O/R X pipe 2 1/2" to FlowMasters
2 1/2" to 3" tips and a Perdator custom tune...(By
Willy from Diablo sport at the Dyno)

Dyno: 466.6rwhp and 497.7 rwtq
A/F @ 4k:12.5-1
A/F @ 45K: 11.5-1
A/F @ 5k: below 10-1
A/F @55k: 10.2-1
A/F @6k: 11.1-1

If some one could host my Dyno graff so all could see PLEASE..

The tunr told me it could be belt slip...(I had the stock belt on before the put the Napa belt 840 and ran this. He told me he was going to put it back to 0 A/F on the Predator) Should I lean it out? If I do lean it out, By how much. It is set at 0 A/F right now....?

I tried to have Diablo do a tune for me. Frankly, the tune sucked.

I ended up contacting JLP (Johnny Lightning) and had him write a tune. It made 40 more HP than diablos, as much more torque, AF was much smoother and a perfect 12.0 across the board (nearly perfectly straight line).
