Yes it is, I just pulled the plug on power package today which is the best deal to get Headers/Intake/Tune & handheld while saving about $300

Am I missing something? I could not find any tune files on the USB drive....or RR-Racing specific instructions. The only thing I was able to do was download my stock tune.

Hey guys. I have attached my dyno results from this weekend. My best run was 365whp with 337 torque having an intake, joe z exhaust, and the rr racing tune. I live in Canada so the altitude is 3557ft and I normally use 94 Octane. The dyno company I ran my test with told me my ISF was running lean from 2500-5000rpm, basically looking for fuel between that range. This somewhat explains why I wasn't hitting 375-380whp like I should be. Rafi is working on an upgrade for this as some ISF owners in Colorado are experiencing the same power loss with the altitude difference. Anyone have a good Octane booster recommendations while I patiently wait? Lol

^^To get a truer picture of your dyno performance, you should have the dyno operator send you the results with the SAE correction factor, rather than the STD. Generally, the SAE correction factor will account for differences in ambient temp, elevation and other factors and allows for dyno comparisons of cars with identical, or very similar, set ups in various locations. To be honest, I am not convinced your "power loss" has anything to do with you running leaner from 2500-5000 rpm. Also, to a point, leaner AFR mixtures tend to make more power than richer mixtures and I don't see a richer AFR mixture earlier in your power band adding power up top.
All that said, I am not as familiar with IS-F dyno-tuned cars as I am with other makes, so maybe there is more power to be extracted here with the approach you are taking. Our engines are, basically, air pumps and, to get more power from them, you must get more air into them by one means or another. From my perspective, I do not see this happening with a boost in octane (unless CDN cars were tuned that way from the factory) or richening up the AFR in the region identified. Still, best of luck in working your way through this.

Whatever revision I got for the tune here at altitude is awesome because my car runs like a bat out of hell after the install!! Throttle response and mid-range are improved tremendously and I usually take weekly trips to Mexico with a few ISF owners and last night I pulled with some of the regulars I usually see taillights on and this time they saw my tails My car is definitely faster with just the tune and I love it!!
Can't wait to get the headers installed here soon as I know I'm not getting the full benefit of the tuned intake without the headers, but let me tell you the sound you get with this intake is almost worth the price of the intake alone! It really makes the car sound mechanical and alive!!
