It does no good to increase the redline limit if the engine's peak horsepower and torque is not best used when each successive transmission gear is engaged. In most cases the car maker has [already] optimally matched the vehicle's engine horsepower and torque with the transmission's gearing. Otherwise, the car maker would not be proud of stating the car's 0 to 60 mph time.

Your questions are fair. Depending on the engine's horsepower and torque curves, along with the transmission gearing, in most cases the car maker has already set the engine redline limit for absolute best performance.

The car absolutely does have more power, and I don't really push it much up to the redline, I shift manually most of the time especially if I'm driving hard. They have dynos on the site I'll post below. Mine is awd I don't know the actual HP numbers with the tune, but I immediately felt a difference with the tune.

They are more or less the same cars engine-wise.

I'm sure my 0-60 time is faster, if I get a good camera setup to show my spedo when I'm driving I'll do some videos. I was probably one of the first with the tunes on the GS but there are a number of others who have it on the IS/RC.

Edit:
Looks like Torque Pro will do it, I bought the app. I'll try to post the data once I get it! Looks like it can measure "bhp" somehow, not sure how accurate that is but I can see what it shows me, I'm curious.

Yes please do a 0-60 comparison. It would be great if the car can do it in the 4 sec. range.
I'm more interested in that than just a feel or placebo effect, cause every time I put a new sticker my car feels faster too.

You can totally forget about that! You'll need at least 385 hp just to get to 5.0 seconds...

HERE is a simple calculator for you.
Total weight of the car with fluids and a driver is debatable. Also, the actual performance of the automatic transmission compared to a manual is debatable...

My rear tires always have problem hooking up, they always lose traction at take offs and the colder weather now just made it worse. These summer Dunlop tires suck, same problem with my old GS' stock summer Bridgestones. My Michelin A/S were way better, rarely any slips, even in the rain.
