I'm not sure what you guys mean by mapping but on the 1st run:
Conditions:93.54F, 30.07 in-Hg, Humidity: 34%, SAE:1.01 Max Power=294.50 Max Torque=334.12 Air/fuel ratio around 13.5 With zero timing.
2nd run:
Conditions:92.62F, 30.06 in-Hg, Humidity:35%, SAE:1.01 Max Power=293.83 Max Torque=334.93 Air/fuel ratio steady at 12 With 14 degrees of timing.
20 minutes in between runs. I don't know if this helps.
Edit: My engine has 39,800 miles. I was looking at Yellow Fever's sig and it seems like I have the same problem he had, all kinds of mods and only 290ish HP. My intercooler temps are cool to the touch with all the LPF mods. I wonder if the boost is causing a blow out in one or more cylinder because of the .045 gap?

Dependent upon boost levels and timing of course, I am willing to bet over 600rwhp

Gap the plugs down around .034. You need to datalog air temp and timing to see where they are at. Sounds like high iat, pulling mad timing. Set a/f to 11.9-12.00.
FYI...... It is hard to impossible to make good hp with the Series I blower and intake manifold design.

Does the series IV really improve it that much? It's only a couple more HP gain than both the series I and II.
Sorry to divert the conversation......00 425 saleen.....try casey's recommendation....but ultimately if it doesn't work out i'd get another recommendation and take it to another tuner to check it out.
Also...did they put in a wideband O2 sensor to monitor the A/F ratio? Where are the monitoring it at?

Okay I'm going to throw this out there based on the fact the model of Saleen from that year speced at 350HP as posted by someone on here...That being said, if adding the blower actually didn't do anything (by all appearances) to your RWHP and RWTQ then I'd have to conclude the orginal engine is not in the car or you're looking at the wrong model.
That makes zero sense how you can add an SC with 8PSI and end up right where you should have been before the S/C. What were you baseline numbers? (HP/TQ BEFORE adding the blower)?

Agreed....go back and see if your tuner did a baseline dyno.

What's baseline? Sorry I'm a noOb with 4.6L engines.
I re-gaped my plugs to.035 and it feels a little better. I ran out of time, but I'm gonna change out the fuel filter next then take it to another tuner.
Evil, they put the O2 sensor at the H-pipe on the left side.
I bet with the re-gapping of plugs and a few extra degrees of timing and another tune I should be ok... I hope.
