Reflashed today using EFIDudes
Went over today for my free dyno and tune 
Being a uber noob with tuning I have no idea what was done besides similar to the racing beat flash. I guess Bill (lolachampcar) can fill in what really was done.
here for the dyno plots
Engine Mods are AEM intake, Full TurboXS exhaust
other possible related info, OEM Fluids(Oils ect) no premix, Mazsport cooling mod, and pretty damn hot in the shop today if that matters at all

You sir need to check your ignition And typically dynos plotted against RPM are easier to read. Looks like it was done in 4th gear based on the RPM figures?
Nice healthy boost of almost 20 in the midrange there... Would be good if they could smooth out those dips some more..

Mazsport ignition upgrade soon. I bet id make much better numbers in that case.
On a side note the car feeels a ton smoother all the way through the powerband

We just did one quick pass using Jim M's advice about pulling a little fuel out above 5500 under load. We literally did one edit and brought A/F from 11.9ish to 12.5ish.
I have before dyno, dyno first pass, dyno second pass and after dyno DataLogs from ProLogger which I will try to get posted along with the before and after fuel tables. This should give a lot more detail on exactly what happened to the A/Fs. There was an ignition pickup on car so I should be able to provide HP v RPM as well.
Again, the idea was to make just one very safe change to demonstrate how one would go about using the tools. A professional tuner with some time could do much better.
Please be patient on the plots, data and the like. Sebring is next weekend and I have some data acquisition work to do for the car along with another trip to the kart track. My neck has had a six month vacation so Sebring is really going to hurt if I do not get some side load abuse before the weekend. Anyway, I may not be able to get things posted until next week.
Thanks again NaarLeven, I really appreciate your help.

I forgot to ask.
Could you please confirm for the boyz and girlz back home how large the thing was that did the logging and reflashing and about how long it took to reflash your car each time?

Logging and reflashing was super easy and super quick.
Maybe about 1 inch wide by 2 inches wide by 3 inches tall, flashing took about a minute. I consider myself a noob and I could very easily load a map myself.
But do you guys really think I have an ignition problem? Will the mazsport upgrade I ordered help in the power department at all?

Glad to see you guys making progress. As for "pretty damn hot in the shop today if that matters at all".... nope, you will get no sympathy from me! I would love to by able to play w/ the car but winter sucks up here.

Here is the first installment of data from the tuning session.
The following are the before (stock), after and delta target lambda tables for Naar's 05. Again, only one edit was made so only one set of changes are shown. I should have the ProLogger data up shortly as my trip got cut short. I hate carbon clutches!

ProLogger Data
Here is the logged data for before and after dyno pulls. We got this data by plugging in an EFIDude ProLogger into the OBDii port. The hardware dongle was no larger than the connector found on a normal OBDii cable and fit up under the dash completely away from the legs.
I've included two plots of the first pass on the factory flash (N3ZBEG for the 05), one showing a mid point in the pull and the second showing max values. I did the same for the after editing and reflashing the PCM (reflashing using the same hardware dongle as used for logging) choosing to plot a mid point and max values for the pull. The actual A/F ratio table edits are in the post above.
You can compare the before and after plots and see that Air/Fuel has come up just a little bit thus accounting for the extra horsepower. I will not begin to suggest where someone should run their A/F ratios, but I will say that we run about .89 to .9 lambda (13.1-13.2 A/F gasoline) on our big cubic inch Ford and Chevy race engines in addition to the two liter Cosworth race engines. I would think there would be a lot more to be had by slowly raising the A/F values.
