Default dynoed - stock vs J's Racing S2k

Thought i just share a dyno done today on a bone stock s2k, compared to a full J's Racing S2k( Intake/Exhaust/Header + test pipe + ECU reflashed).

I did this to satisfy my own curiousity as I had never done a baseline dyno on my J's car. The aim is to see what differences it makes if any, and to determine for yourself if it is worthwhile.

The only variable/differences I can think so:
1.Both Dyno sessions were done in the evening on different days
2.stock s2k will be the equailvent of the CR version in the States.J's is a MY07 AP2
3.stock s2k running on 255 rear, J's car on 245 rear

Note the dyno was run in 5th gear, as th J's car was skipping too much running in 4th.

p.s its a roller dyno

Great post! I have the parts. Well, almost the same. J's 70RR, SPL Racing Header, spoon snorkel (gutted air box), and Greddy EMU. Unfortunately, I haven't had time to install any of it yet. Postponed until after the winter

How does she feel on the road? I would like to know how the numbers translate on the street.

By the way I can't tell exactly from the graph readout but it looks like a healthy 250whp/232tq?

the car feels more responsive across the power band, doesnt feel so like like a Honda Civic below vtec point, which is just under 5k.
