overall very happy with the tune. i wish i had that extra 0.5L to get the much better torque '06-'07 owners get, but i'm not complaining. difference between using the Cobb OTS VF39 map and this one is night and day

Wildly optimistic dyno.

Still, an uncorrected 24Xwhp on 91 octane is nothing to sneeze at from a 2.0l. Good job!

I would've said a very conservative dyno. Baseline for a stock 2.0L WRX was 200/200. So he got a ~90 whp gain with all that. Stage 2 2.0L can get a 70whp just from a protuned stage 2.

How is that optimistic?

How is that optimistic? Let's see... The stock car was rated at 227 from the factory. The dyno shows 200 at the wheels. That translates to a 12% drivetrain loss. For an awd car. Sure. Very reasonable.

But the dyno is a useful tool for comparison purposes, and if he saw a 90 hp gain on the same dyno, then he has achieved a good increase even if his measuring stick reads high.

What he and you need to keep in mind is that with his 12% drivetrain loss factored in, his 289 whp car is only making 328 hp at the crank. His 289 whp doesn't mean he has 30-40 hp more than everyone else with a 2.0 VF39.

End transmission.

if you guys want another comparison, my friend's stage 2 (2.0L '05) with UP DP and CBE made 240/231 on the same dyno. the 200/200 number i pulled off another car's chart who i don't know (same dyno tho).

very nice.
i just put my car on the dyno on saturday. same type of dyno but i made a bit less than you. 266hp @ 6800 /255tq @ 4400

the only difference between our cars(besides year) is i have a v7 block, stock header(ported), stock up-pipe(gutted), catless dp, stock boost controller, 93 instead of 91 and a little less boost, no ap. and RA gears. so with that in mind, if everything else was damn close to the same, a header and up pipe = good gain.

Nice Numbers!
Im looking to do pretty much the same thing this winter but on 93 oct and no cat on my dp so I'm hoping for over 300whp and over 280wtq.

93 oct? Let us know what psi you run and the numbers you put down of course. A dyno graph will help also.

Holy late spool Batman! That thing should be fully spooled a good 700 RPMs sooner. Good power no doubt, but the powerband is shifted to the right more than seems necessary.

The peak numbers seem to be right where they should be, a solid setup!

Unless I'm reading his mod list wrong he is running the stock intake, which maybe the cause of some of that lag.

could that really be a big restriction? from everything i read, i didn't think it would be too much of a gain so i forewent getting a CAI or short-ram and just stuck with stock airbox (no resonator/snorkel).

At your power level, it could definitely help, though it's hard to say just how much it would. I still wouldn't see it gaining you 700 RPMs of spool though.

As I said you're making good power, but not even making close to 10psi by 3500 is not quite right... The right half of the graph looks good, the left half not as much

It looks like they didnt start the pull until around 3,000 RPM. Which would make sense why it takes 1000 RPM to spool up. Start that pull at 22-2300 RPM and I bet full boost comes on a good deal quicker.

Your right though....I would've expected that torque peak at 4000. not 4500.

I didn't see him post a boost graph? how do you know what his boost is at and when? no offense...

tuners get to decide what his graph will look like by how he achieves his torque

it looks completely normal and like a nice strong tune to me on a ej205

the boost is the dotted line (look at the right side scale)
