Sport mode in IS350

Technically no. The Lexus 2IS350's ECT Power option will only alter throttle responsiveness as well as provide a more aggressive transmission behavior while in auto (keeping gears up to redline longer, downshifting to lower gears more often, and holding a lower gear when braking aggressively). Our transmissions have a "S" mode but it's more for limiting gears than an actual sport mode.
Sport mode is found on the IS-F and not only will it alter transmission behavior and throttle response but it will also increase steering weight and modify the VDIM parameters to allow a higher handling threshold before the stability controls intervene. The 3IS350 also has a Sport and Sport plus mode similar to the IS-F but I don't believe VDIM parameters are altered (it does however have an adjustable suspension).
You can adapt the Sport mode found in the IS-F to the 2IS350 by upgrading to the IS-F Steering ECU. By doing so, you'll technically have all the same features found in Sport mode with the IS-F by having a heavier steering feel with improved steering feedback as well as an improved VDIM threshold for more aggressive driving.

Wow, that's a really detailed response, much obliged for that. So the sport mode is more for the steering wheel feeling, I think I better save some money for the ISF steering ECU. Also, when you say driving an automatic transmission car manually, what does it mean? You actually have to change gears?

The manual mode on the 2IS is not a true manual shift mode as mentioned - it can be used as such and lots of people do which is fine. Its more so to be used when you don't want the car to shift higher then the chosen gear (say your in town in traffic and you only want to go up to 4th gear).
Many vehicles out these days (including the ISF) will actually have fully manual trip tronic shifters that require you to change gear up and down - the IS will shift down automatically but again will not shift higher then the gear you've chosen that shows up to the right of your speed tach.
My buddy has a 2012 M3 that has trip tronic shifters (dual clutch) and holy hell does it shift quick !!
FYI - my car stays in "power mode"

Choose between the 11-12 IS-F Steering ECU or the 13-14 IS-F Steering ECU.
While having the 08-10 IS-F Steering ECU is better than using the stock IS350 Steering ECU, there were very noticeable and significant improvements made to the steering feel and feedback with the 11+ IS-F Steering ECU which had a lot of the 08-10 IS-F owners making the upgrade.
Based on the IS-F Steering ECU thread, it's not known what additional tweaks were made to the 13-14 IS-F Steering ECU but it does cost $100-200 more than the 11-12 IS-F Steering ECU.
My best value pick is the 11-12 IS-F Steering ECU which is the version most other folks on the forums tend to gravitate to. Combine this with an aftermarket LCA upgrade and you'll be golden!

They pop up time to time here in the classifieds section when people go to part out, eBay, a new one from one of the various Lexus parts sites (My LParts has a discount for CL members), or junkyards (TLS has a few 2008 modules, LKQ, etc)... The ones people list on here tend to go very quick though. Be ready to shell out $2-300+ for a 11+ ECU.

2-300$, that's a pretty good deal there. I've been looking around online, 11-12 in the high $400, 13-14 up to $700+. My LParts is in the same range, the CL5 coupon helps quite a bit but since they are in N CAL, I'm in S CAL, sale tax will bring the total right back up.

Yeah, I got my '11-12 IS-F Steering ECU in the high $400s from Sewell Lexus a couple of years ago.
Since you're literally holding onto the steering wheel at nearly every moment of your drive, this upgrade is something you would notice and benefit from more so than most other mods.
