Dyno advice?

So I put my car on the dyno today (finally), and pulled 200 whp/205 lb/ft at the wheels.

Here's my car's drivetrain/engine mods in a nutshell:

Catback exhaust (2.5" to 3").

Stock DP (with cats).

Stock UPpipe (with cats).

Car's been ECU protuned...ran 15.8 psi.



My question is this:

Are these figures too low? I'm looking at a brochure from MRT/Ecutek...they claimed 225 whp on a WRX with stock DP and only a 3" axleback, and 15.9 psi.

What's the deal?

I read through the article more closely:

1) MRT claims they got 187 whp from their STOCK WRX. Which means they have an amazing 18% Drivetrain loss on their dyno. Dum_dum had quoted an average of 25?

2) They ran the car on 98 RON octane to get the 225 whp. My car ran on a 91-92 octane equivalent in your country. Would this account for the difference also?

you are right there in the average stage 2 HP range, at our shop we get between 200-210.

If it's worth doing, it's worth overdoing
