I have another question.

would the drop off pass 4k RPM simply for fuel efficiency? or intentionally capping the power so they could market a lower performing car and price point?

would the fuel consumption after the tune be on par with the current IS350? it will be interesting to see fuel consumption comparison on this as well

Any idea how this will affect warranty? Would you be able to flash back to factory ? Does the flash leave a time stamp/log/write history?

My unit should be arriving today, can't wait to test it out!

considering the mass majority owning IS300 over IS350, this could be a very interesting topic and will gain interest over time. I probably wont do anything as long as my Warranty remains, but if I still have this car when it runs out. an ECU tune is without question

Tune comes with a handheld OBD programmer. This programmer stores the tuned and stock files. You can flash back to stock.

Regarding fuel economy, anytime you make more power, you use more fuel. That said, if you drive normally without using the maximum power of the car, there will be no change in fuel economy.

Just started a new vendor thread on our ECU tuning, and will also be posting updates on our Supercharger development:

do you have the dyno number for full exhaust before tune? The differences between tune vs exhaust + tune are 5 torque and 15 whp so I assumed full exhaust provide that much gain, am I correct on this one?

I sent my ID file to RR last night, just waiting for them to send the files back. The unit is a bit bigger than I was expecting, I was thinking something around the same size as COBB. However it is pretty fast!!!

Sorry, we did skip that step because we have seen many other exhaust before/after pulls on the IS350 on dynojet, and i feel the consensus is 10hp gain from a full exhaust (no tune), not 15. The tune makes a bit more power with exhaust vs. without.

Will the tune provided cause any issues for owners in higher elevations? (I live in Edmonton, AB at a 2000+ft elevation)

Thank you for your time!

I put the tune on late last night so I've only had it for about 12hrs on my 300 but what a difference. My Butt Dyno is loving it, pulls a lot better withe less lag when you hit the gas. I haven't driven the 350 but I'm guessing this is close to what that must be like. The car is transformed with this tune, hoping to Dyno it this summer to see what the numbers are.

I know they are working on a supercharger, something I may invest in down the road once my warranty expires.

Is it still the same smooth linear power delivery? Just more power? Im looking to get this tune just want to see some feedback first.

Since the tune changes the redline.. Will it change where the redline mark is on my cluster?

Its a long shot question but still worth a shot considering its a full LCD screen.
