I got tuned*Updated w/Graph...

And by increase timing you mean more towards the (+) side??? Cause if that’s the case then no...More timing was pulled away in the map when the car was richened up...

It is possible that the amount of time that the car spent on the dyno paid dividends in power output. The AFR was 11:1 on the 91 octane map and a really really conservative 11.2:1 on the 100 octane map.
The correction factor was 1:04 which is close to what you got. Uncorrected the power would have been 287 whp on 91 octane and 300 whp on 100 octane.

And I do have a high flow cat on my car...AMS 3" TBE and thier HFC...
So Chevron 91 Oct and HFC are robbing me...what else can i do to help my car out before going turbo kit???
I also had someone on another forum tell me that the dips in my graph are a bit odd...what could cause that???

1. A test pipe will more than likely free 10 hp over the HFC. Make sure that you get a 3 inch test pipe and not one that pretends to be 3 inch like the one I got
2. According to Shiv, the Evo likes the 76 gasoline best. Alfred @ TT told to fill from a 76 station before I dynoed. Since I have dynoed I have only used gas from a 76 station. Recently, I have been mixxing 100 octane with 91 octane to get the desired 93 octane.

Here is the down and dirty on my Dyno Day...
Conditions on the Dyno: between 108 and 110 Degrees (Yeah, flipping hot), 4% Humidity
Blue lines are from the Vishnu Baseline Map and Red lines are the tuned results:
I am extremely happy with my results from today...with the temps in the 110's and a Cat restricting flow, 305 WHP is not bad at all...Also turns out that the car was running too lean then pig rich (That’s what I get for trusting a narrow band Auto meter A/F meter...lol...wideband is next)...
On the 91 Oct baseline map from Vishnu (Blue lines) the car peaked: 294 WHP @ 6800 RPM and 268 Ft. Lbs. @ 5200 RPM w/ A/F ratios ranging from 13.1 low end to 12.0 high end
On the 91 Oct tuned map from Tuning Technologies (Red lines) the car peaked: 305 WHP @ 6800 RPM and 279 Ft. Lbs. @ 5000 RPM w/ A/F ratios ranging from 12.0 low end to 11.1 high end
Gains within the power band are as follow:
Low End
27 WHP and 33 Ft. Lbs. @ 4200 RPMs / AFR went from 13.1 to 12.0
Mid Range
16 WHP and 17 Ft. Lbs. @ 5300 RPMs / AFR went from 12.8 to 11.7
High End
18 WHP and 15 Ft. Lbs. @ 6800 RPMs / AFR went from 12.0 to 11.1
All comments, remarks and questions are more than welcomed...

This is the baseline map which is found on the Vishnu site...
Here are the maps after the tune...

On the same DYNO with a stage 1 custom tune and no SMART I made.
I have a stage 1 (SHIV Tune)
HKS Exhaust
Helix DP
UR highflow cat
Fidanza Cam Gears
Walbro Fuel pump
K&N drop in filter
NGK Iriduim plugs
Here is my Car on 109 unleaded
So here is the dyno of my results of 100 octance custom tune running 109 Unleaded. The AF sensor came off at the end as you can see on the graph.
Not bad for a turboback, camgears, xede and fuel pump. I don't have a hotside. Also it appears I was loosing a little boost since my TQ curve fluctuated.
The boost was 25 psi tappering to 18 at redline

Alfred told me that I should get a test pipe and lower intercooler pipe and the car should be seeing the 320WHP area with no problems...
Also, your AFRs are pretty high too as to mine start off at 12 and safely go to 11 up on top...
On this Dyno session I only had 10 runs total for an hour of tuning...I am pretty sure with some more time and cooler temps I can squeeze some more numbers out of the car playing with the cam gear settings are trying to work out my restrictive timing...

so no, SMART has nothing to do with the tune while on the dyno...
I definitely agree with alan678 that the temps/conditions that he dynoed at were not the best recipe for good horsepower/torque numbers. When I dynoed at Tuning Technologies in July 2005, Shiv was able to do about 308 whp and 280 lbs tq on 91 octane with a water injection mix. With 100 octane, I was able to do about 322 whp and 285 lbs tq. This was also done on a hot day, but it cooled down to 98 degrees when I dynoed in the evening. I had a basic Stage 1 W/ S.M.A.R.T. running with a 3" cat.
Snoop, your Stage 1 dyno numbers are great. They are the highest dyno numbers I've seen on a Stage 1 so far. I'm very curious, what are your trap speeds in the 1/4 mile? I was able to trap 108 MPH in Fontana. I'm sure I could have done 110-111 MPH if my clutch wasn't locking me out of 2 of the 4 gears. I'm having a twin disk installed soon and hope to return to Fontana for another try.
