Are these OK dyno results????
I have just had my truck tested at the local Dyno with all my new goodies fitted (4# lower and JLP predator tune) and I am a bit disappointed in the results. After tweaking the AF a little to get it nicely into the mid 11s (because it was initially running a bit lean) my results were 366.6 RWHP and 464.3 RWTQ @65deg . Does this sound right, because I get straight to 12 PSI on my boost gauge and would have expected more, like 380 RWHP? Although when the truck was being dynoed I logged everything and noticed the timing was only at 14.75 deg @WOT. If I advanced the timing 1 more degree or so would it give me noticeably more horsepower and still be safe?
Previously I had the 2.8" upper and predator pulley tune and made 372RWHP and 452RWTQ @90deg, although this was running almost 19 deg of timing

From what I've seen, timing is crucial in getting max power. You just don't want ping because that's the number one reason for blown motors (rods can't take the rattling).
