Here are some of the dyno day results. Horsepower and torque first, then AFR and boost if taken. If you have any questions about the graphs just let me know and I can explain.

Thanks Mike.
Does these dyno numbers reflect any type of artificial adjustment from the temp/humidity? I know some dynos report SAE HP which is adjusted, right? Do you know what the temps were?

Probably about the same as Rochester - damn hot and as close to 100% humidity as you would ever want to get.
Probably hotter and more humid than it was in Shreveport! |

Larry:
Every graph you see on my dyno is corrected for:
ambient air temp
humidity
barometric pressure
air inlet temp
This keeps the numbers consistent from day to day. I've had the same car show up different days with very different conditions and the graphs laid right on top of each other.
Ambient air temp was 85-96 throughout the day.
Pressure was 29.91-29.95.
Humidity was 87 in the morning and dropped to 37 towards the end of the day.
Inlet air temps were 90-115 depending on the car.

LOL at my boost numbers.
not too bad for 93 oct, with 125* IC water on that pull (3rd)
And I only hit like 323whp or somthing on my street 17deg timming. 2nd pull I turned it up to 21* were I don't see KR really but I'm safe on the street (ok I turn it up for kill mode).The 21 deg timming made 340.x whp and car was hotter. I think I saw a 0.x and a 1.x blimp of KR so I knew I was maxed for 93 octane. LOL But had a pull left, so just wanted to try somthing. So went to 24* timming and the line, started to pull away for the last 340whp pull. from about 4950 to 5750 it was about 5hp over last curve. And crossed under was was 5hp less till 6100, then there about the same falling off to 6500.
I didn't save the Atap. or look at my wideband 3dr pull. But was at about 12.0-12.3 1st and 2nd pull I think? (anyone esle watch it?) I wish I added a little fule and got it to hi 11.'s knowing th car was getting hotting abf going to get soem KR. 3rd pull I saw a 3* eaily, 0 for alittle shile then a 5 spike to a 4. So started getting the 4* pulled in KR probally were the 5800+ about was.
Mike could you post the screen shot that has all 3 of my pulls? I have it here too. anyone have a scanner? I think it's some great info about no other changes and showing power incress from timming advace. I htink I read +1 deg is 2whp? I donno? But a broad curve for 323 at 17* to 340 with 21* is pretty good. LOL
I only hade about 5mins with the widband too. LOL It's 4654565652's better then factory gayness. I think when larry was watching for me on the street. I was seeing 12.1-12.3's (maybe a 12.4?) but my 02's were rich at .940's LOL I'm happy with my upstate, CAI, heads,M90. _________________ New Era performance

oh ya. I donno about that? Mike told me after? But the power band is still that same. maybe if I can get that dip out thats were the peak is? LOL my peak at 5700 seamed like a low rpm. it pulls 5800-6200 really hard. were Pshift is off you can tell. it's short shifts bad.
I just noticed I have the boost wave in that exate same spot? I wish I have a AFR numbers to see what was going on there? Anyone have a idea? |

Correct. Everyone ran in 3rd except Larry who ran in 2nd at his request. |

I don't know?? I pulled an 208.7 I think it should be more than that. Could it be that I didn't turn off the Traction control??? Would that effect my pull? Anyone Know?? |

No that shouldn't make a difference as you're not spinning the wheels on the rollers. |

I'd say 208 wouldn't be far off....assuming 20% drivetrain loss.
208.7*1.2= 250.44...I wouldn't bet against the missing 10hp being due to the stock PCM tuning. I also don't believe that replacing the stock airbox (on 04+) alone would allow for that much better breathing (all else being stock)--we don't have the wacky bends the previous gen. does.
