ISP,
Great job on the numbers, BUT I have to add that even with the Tomies you plan to run I seriously doubt you will see anything that will resemble a curve. Even if the vehicle is designed for nitrous.
I have tomie's in My car. Great pair but I just don't know with that graph and your particular setup....
I wish you luck at the track this weekend. I know you will do well.

Awesome numbers, 800+ w/o juice is impressive! I have a couple questions, please don't take it as hating because I am curious.

What size exhaust housing are you using? For a 42 that is an extremely weak powerband.

I've never seen a torque peak at ~8300rpm's what is up with that?

And what is with the different gain factors on the two sheets? How does that effect the graph?

Nice power , but how does it drive on the street? I would think it feels like a N/A until 6.5K where the rush snaps your neck back for the next 2500 rpms.

nitrous should change the curve quite a bit

Might have to do with the dyno (hopefully? ). Dynapaks are cool because you can simulate ramp-up load/speed, etc and well as tune at different loads as well. If the ramp up and load isn't quite right compared to what would happen on the street, it can affect spool up, obviously. I've seen it happen at other shops that had fairly new dynapaks that weren't totally dialed in correctly.

Shearer: We are also discussing the torque peaking @ 8300rpm's, we believe me might have the answer.
