HP and Torque gains

[zagain]

What are the estimated HP and Torque gains over stock with;
1) Just a JB4 on map 2
2 Non catted downpipe and JB4 on Map 3 and map 4?
Both with 93 octane fuel.

Unsure on exact JB4 gains, but I’ve attached a photo of our average gains on EcuTek with modifications as follows.

I didn’t realize stock boost is only 12 psi.
What if you run stage 2 tune with a stock dp? It will just have lower hp and richer a/f?

It’s just more what we offer as a “stage 2” package.

We can 100% custom tune your setup specifically for your modifications with no problem.

Someone wanting an off the shelf file, would just receive the one they need.

If you have any questions, feel free to reach out.

When you quote boost figures as in the above post, where is the boost actually measured? Is it at the charge pipe before the intercooler or is it manifold pressure after the intercooler?

It is actually highly variable. The car looks for a torque target and will adjust airflow depending on he environment to get hte power. So if its warm out and the timing is pulled back it would need aditional airflow to produce the same power level. Or if you were at a high elevation it would increase air flow. The car also runs in aboslute air pressure for its calculations so in Denver the absolute pressure of 2Bar is much different than Los Angeles.
