The F Sport trim is just a package that doesn't effect the drivetrain...it's mostly trim, suspension, rims, brake pads, front bumper, and a few other little things.
It's not like the difference between a GS350 F Sport and a GS-F...which are completely different vehicles when it comes to engine.

When you're talking about the IS300 with the 3.5L V6, there's no difference between an IS300, IS300 F Sport, IS350, and IS350 F Sport...in terms of the engine.

Does this effect the shift points between normal and sport mode?
I’m not to experienced with this stuff but I was wondering, will the ecu tune effect the shift points between normal and sport mode? I’ve noticed in normal it shifts at lower rpm and sport at higher. Will it shift now at even higher rpms in both modes? Is this safe for my motor? And just so I’m clear, if I buy the kit with headers, exhaust and the handheld unit I still have to send my ecu in to get flashed?

Now by saying this, there is a noticeable difference between the untune and tuned even driving in normal mode. I only got the car for a month when I went on the tune and I really can tell the difference.

Yes, I agree, most definitely would do it if I could buy the hand held unit like previous years. I just can’t go without a vehicle to mail in my ecu. I am sure it’s a quick turnaround, but mine is a daily driver.

They have the update available for 17 IS300 now at RR Racing. Patiently waiting to buy mine, but prior financial obligations have me tied up. Hopefully in the next couple of weeks. 😁
