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.
