This is a discussion on What's your theory on the RS NOT giving out advertised power numbers?

I have had no real issues with the performance of the RS, but the way it goes about delivering the power and torque did feel lack lustre sometimes. Whilst the Cobb OTS tune doesn't deliver huge power gains over stock, the way the car now drives is chalk and cheese compared to stock.
I suppose this is the point I am trying to make, even if the power and torque of the Cobb OTS tune where the same as stock, the OTS tune has just cleaned up the inconsistencies in the factory tune. Just the way it puts the power down and holds torque now high into the revs was enough for me to be sold and the first thoughts in my mind was, "now that's how it should be"
Actually the Rallysport Direct build thread has a good video review of the difference that can be felt with the Cobb OTS. Sort of sums up the same impression I got.

Perrin proved that the factory reflash removed 20whp on the 08 STi's. Very frustrating the feeling of being decieved, but with the RS several factors are involved. So far I would not be worried because a proper tune is the cure all. I saw one dyno estimate bhp to be 378 on one car then 348 on another.

Do a little drag race against the STi and see what happens. You actually have the ability to do that why not try it.

Finally hit 1k on my RS and gave it the beans on a 3rd gear highway pull (in sport) - felt amazing! Then after exiting the highway and starting from a stop....it felt like my girlfriends 16 Elantra in first and second gear. I turned the car on and off, drove around some more...tried again from 1st to 2nd - same lackluster results. I know ford limits the first gears to preserve the drivetrain....but my butt dyno had it at 160hp.
Is this what others are experiencing?
For me, the car pulls much harder in 3rd gear than any others. It feels consistent all of the time.
The speedo raises much faster than the car feels it's going...meaning at the top of third on a decent pull I'm easily clipping 80 or 90.
Hard to do that legally, or safely so it doesn't happen often, but I've only felt the car really down on power when I swtich from a tank of 93 to a tank of 91. I really wish I knew of some reliable octane boosters that I could just carry around when I don't feel like driving halfway across the city to the ONE station that sells 93 (at twice the price per gallon of 91!!)

So is the car really false HP? I know in 1st gear it limits the power. Is there more to it than that? Reading a couple posts looks like there is....?
