Well I just ordered stage 2 for my 06 TR and I am quite baffled by the hp ratings. I was comparing the dyno charts for stage 2 on cobbs website and the flash gives the 2.0 engines +50hp and only gives the 2.5 engines +20hp. So they are both even pretty much even in the end. Did we get a washed down tune just so it comes out "fair" for both displacements 2.5 as the 2.0?:confused:

area under the curve, go check it out. Look at the increase in torque. You will definitely enjoy it, trust me!

The '06 WRXs are woefully underrated from the factory. It's to the tune of about 30 HP. Peak HP is about the same on a Stage 2 2.0 versus a 2.5, but the 2.5 has a much more broad curve and torque on the 2.5 is insane.

not to mention, your 2.5 block is pushing much more air and will easily over power your turbo within a few mods.

Yea, don't worry man, my 2.0 is wicked fast with the AP, but I drove my cousin's 06' and felt power a lot quicker down low. You'll love it.
