On the first dyno session, 1st run, I did baseline at 279.49whp and 296.27wtq.
The conditions are:
- 91 octane
- JB4 turned off
- Air filter (which very minimal hp gain)
- Charge pipe (very minimal hp gain, but eliminate turbo lag)
- Muffler (minimal hp gain, averaged 10-15hp in my experience)
On the 2nd run, I did 313.27whp and 362.65wtq.
The condition are the same as above but with JB4 at map 2.
So with that, it concludes, with JB4 only, it gives out 33.78whp and 66.38wtq gain.
If you have 93 octane, you will see more gain.
Also, I just recently did 2% mix of E85 while on map 2.
I may try 30% E85 mix soon, but it is more complicated on the setup. But, I've read that it is very rewarding.
