Basically, your car must be in good condition, good seatbelt or harness, good brakes, no missing lug nuts, good battery holder. No loose objects in the car. The car will be checked before getting onto the track. Loaner helmets are available if you don't have one.

I'm planning to get the car back to the dyno with the new Enhanced-DIYPNP to check the tune for next season. This evening I decided to check things out first. I changed the EFR V-band clamp with the beefier one from Treadstone.

Those are GREAT numbers for such low pressure, 'GRATS MAN 
Something kinda bugs me though: the area between 3600-5200. Looks like its either boost or spark limited to look that way, and could have been rounded to the left a little bit like the rest of the curve and other "normal" curves
Also any reason you didnt' wind it out to at least 7? Looks like it woulda kept making power

I have read this all before, but to save me from doing so again, can you please recap what your engine specs are? I am building an EFR6258 very soon and want to know how my setup compares to yours. Great thread with lots of pictures, thank you. So, compression ratio? Head work? intake? The important stuff that determines those numbers? Thanks in advance!

Great numbers! Everyone is right about the mid torque and getting that torque up should help with perhaps more power up top!
I believe it is in his signature!

Thanks all!
I mentioned to him while we were tuning that it seemed to have a flat spot in the middle. After viewing logs of the pulls he saw that some timing was being pulled. I'm not sure it its related to the flat spot. Reverant's new ECU has some sweet knock sensing settings. In the end, the tuner pulled some timing to avoid it. The summer will be worse so, the timing map will be a good starting point to let the ECU compensate.
The head is a 99 head that has the ports smoothed to remove casting flash, the valve ports were smoothed to have better transitions to the valves, the combustion chambers were smoothed out and valves were deshrouded.
I can send logs to you Scott. email OK? (I have it.)
