I would say the gains are the same....How much more power does the ISS track system make compared to the JoeZ?
Here are my Independent Dyno Results.. 22-39 RWHP...

~ Released & Debuted @ SEMA 2008 Las Vegas ~
- As a disclosure to ALL, our Best Pump / Fuel choice is only 91 Octane for our IS-F, here in Southern California.
Below is the Dynojet graph of ALL the 6th Gear Runs with the New Exhaust System installed...
This independently tested system, included Two properly tuned resonators & mufflers for optimal performace gains while retaining the ultimate Lexus experience.
Base / Stock Dyno test was 333 Rwhp & 336 Rtq
Run 11 (361.8 Rwhp / 356.4 Tq) = 1st run after initial setup and safety test spin on the dyno
29 Rwhp Gain over stock
* Run 12 (354.8 Rwhp / 353.8 Tq) = 2nd run, which is right after the 1st run.
This run best represents normal operating temps.
This is the run we used to compare with the base numbers.
* 22 Rwhp Gain over stock
Run 15 (371.8 Rwhp / 357.2 Tq) = 5th run which was the last run.
This was just after the two 5th gear runs and a 5 minute shut down / cool down of the engine...
Best numbers of the day due to cooling period.
39 Rwhp Gain over stock
