Default Cobb Stage 1 comparison

I had an '05 WRX wagon and Stage 1 on a Cobb AP was very subtle. It mostly seemed to smooth things out. I noticed it most when I flashed back to stock and the power was lacking a bit.

On my '06 WRX wagon, the difference from stock to Stage 1 is more noticeable. Turbo lag is reduced a lot, and power comes much more quickly in gears 1-3. I'm sure the 2.5 engine has something to do with the difference.

BTW, I'm running 93 octane.

I had the stage 1 on my 2002 Wagon and it definitely smoothed out the power band, but, I don't think it made my car much faster, just more smooth.

Then, I put on an Invidia, catted downpipe and moved up to stage 2.

WHOA NELLY!

IMO, the AP isn't worth it unless you go to stage 2

I really disagree. I just went stage 1 on my 06 and I like it so much better than stock that I am worried I will regret going stage 2 (but I am going to risk it ).

Stage 2 wonderful...

But if you're like the rest of us, it'll leave you wanting more! You can never have enough boost!

I think stage 1 is worth it. The car feels "healthier" and you alwaya have the option of going to stage 2 if you want.

"IMO, the AP isn't worth it unless you go to stage 2 "

I think I disagree, but I haven't gone stage II yet. With EM, a manual boost control and Invidia uppipe the car is much stronger and the EM definitely smooths out the power. It's totally worth the money and upgrade just to those 3 things. I'm saving up for a turbo back exhaust, pretty huge feel in horsepower, huh? I think the car is plenty fast now, I just want the sound of a better exhaust really. I'm going to get the Invidia catted DP, and AVO exhaust.

Actually some form of engine management is highly recommend on the 04+ cars (mildly modded) because of the long transition periods in OL/CL. If you're doing the turbo back, you can put down an extra 20whp just by retuning the car. We do this all the time for our customers that only have a turbo back system.

Cheers,

Gary

I think Stage I was much better then stage II, sure stage I didn't have the overall power increase that stage II had but stage one is just a flash, stage II is a flash with exhaust bolt ons so most or alot of the power from stage II is comming from taking the cats off and not from the flash itself. Stage I made my wrx much smoother and more drivable stage II just made it a little quicker, i would take the driveability over the speed anyday.

^^ Interesting point of view. I'm sure many people would disagree with you, but I agree that Stage 1 feels great. I wonder how much of the power gain at Stage 2 actually comes from the AP considering the big difference a new TBE makes by itself.

haha that's a pretty funny argument. you do realize that EM itself isn't waht makes the car faster rite? the reason why stage 1 added more power is because the car wasn't tuned to the max from the factory so there's room for improvement. at stage 2 i would say half the power comes from the exhaust and the other half from the flash that corresponds to the exhaust.

there's only so much a flash can do to your car... actually, EM is done according to what you have on your car. without mods EM is pretty much useless (if the car was tuned to the max from the factory).

also i don't understand what you meant by "i would take the driveability over the speed anyday." it's not like stage 2 isn't driveable... in fact it's more driveable than stage 1.

Stage 1 is great because it makes the car feel top-notch in "stock" form. The quietness of a stock car, but the overall experience compared to the crap stock program is night and day in my opinion.

Stage 2 is awesome, because it no longer has the "stock" feel to it. You've got a TBE on it now, its going to be louder, its going to be quicker, its going to smell and it won't feel like a grocery getter anymore. Its really 2 different animals.

Had similar results with stg1. Ran it for around a month and the shifting was much smoother with a slight power gain. Stg2, though, really brought out the extra get-up-and-go.

$500+ for the accessport was worth it, but it's well worth the additional $600 for a helix catted dp and sti uppipe/catback (at least this was my setup decision). It's stealthy, gots a slew more power and completely reliable. I do need to get a protune, though...

Never tried stage 1 just stage 2, but my increase in speed was probably more then all of you combined.

The same time that I went stage 2 I finally fixed my wastegate pressue boosting. This means I went from an untuned 7 psi to a tuned 16 psi. Holy cow. The car is soooooooooooooo much more fun to drive. Even going to get groceries and not taking it passed 4k it is way more fun. This plus the grounding mod made my car soooo much smoother and more driveable.

Not true if you've got an '04 or '05 WRX.

Stage 1 is powerful medicine for those cars.

who cares, the great thing about the AP is you can go stage1,2, or 2.5 anytime you want. There is no worth it or not for stage1!


with that said.. Stage2 owns.. but it leaves you wanting more for sure

^I upgraded to stage 1 on my '04 after already having a catless uppipe and IC hoses. The difference was noticeable. I then added a catback this spring and the car feels even better. On an 04-05 an AP and a catless uppipe is must have and is how the car should have came from factory.

I imagine a lot of it has to do with how much you are expecting out of it, and how "in touch" you are with the car's performance.

I have an 06, and from the underwhelming dyno numbers (something like .4hp at peak) I wasn't expecting much. Tack on to that that I came from an NA car before, where a big increase from a bolton mod was 5hp, I wasn't expecting the AP to do much for me when I flashed to stage 1.

But overall, I was extremely impressed once I got behind the wheel. The powerband smoothness in the 2000-4000 range was impressive. No hesitation, just pure oomph.

I can't wait until stage 2
