Default Something wrong with my AP?

i just installed a ap on my 06 wrx. my other mods are a megan header, dp, maddad 3/2.5 catless midepipe and a sti muffler. i also have a maddad cel fix installed but it did not work so i do not think it has anything to do with the problem. before the ap was installed i had a cel and checked it with a friends cel reader so i know i have a cel. now i have tape over the check engine part of the dash beacause it was annyoing. i installed the stage 2 93 map, check and the ap said it was the current map. i did check cel and it said i did not have any. then i drove the car and it feels exactly the same. boost stayed the same at 11psi in 2nd and spiking 13, tapering to 11 then down to about 5 by redline.

Is the map propelry installed? I am very dissapointed if i spent $645 and did not feel any increase in power.

What boost are you hitting in third and fourth? 2nd is not a good indicator of peak boost. Also, the heat and humidity in south Florida are not helping you out.

1. Post in the right forum. The 2.5L forum isn't the catch-all for all your questions.
2. Quit complaining about lack of power/boost when you haven't followed Cobb's path for success. Their path says: Stage 2 = full 2" TBE. You don't have one, so you won't see the full power. That's YOUR fault, NOT theirs. Research twice, purchase once.
3. Kwetching about a CEL without giving us the PXXXX code does no one any good. If we know it was a P0419 code for example, we could help. Not posting the code does nothing for anyone.

You should call cobb and see if they make a High Wastegate duty cycle map for the 06 WRX. They make them for the STi but i just checked cobb's site and didnt see one for the WRX. But heres what it says about the STi
"Stage 2 mapping with higher Wastegate Duty Cycle mapping for those unable to hit the boost targets."
http://cobbtuning.com/sti/accessport/index.html

Also, your map is not for headers. And do you have an intake? Cobb off the shelf maps do bad with aftermarket intakes, from what i have heard. So if you have an intake, maybe the combo of the intake and headers is screwing something.

Also, it may take several weeks for the computer to "learn" after you load the map. Give it time. I said the same thing the night i installed mine. I said "Its louder but it doesnt feel faster" Now its several weeks later and it feels faster.

Did the AP on my 06 as well and didnt notice much. Did a third gear pull next to a buddie with an 02-03 running the stage 1 map and we stayed even. The only power i had on him was low end. I have the stock boost gauge and pretty much hold a little less then a bar in each gear. 4th and 5 i go a little over. I think a bar is somting around 13-14 psi.

So yeah all in all i didnt notice much. I sold the AP and got a Ecutek. Not much change. In fact i wish i kept the AP because i ended up getting a new VF-39 and Sti TMIC from a local forum and wouldnt half to pay for a retune.

My two cents would to go from stock to stage 3

so the header is really making that much of a difference. How would that be affecting boost levels?

would trading this header for a sti top mount be a good decision?

also will a stock manfiold from a 02 wrx fit on my 06 wrx?

I used to hit just under 1 bar with stage 2 on my '06. I switched to a map from TDC and now have no problem hitting 16-16.5 psi in 3rd. My KC values are better with the TDC map. No more negative values!

Man....you just don't get it. STOP modding your car until you have gotten a full 3" TBE. Once you have that, then you can add stuff and only then if you are getting a protune to make up for it. Start with a good base first and QUIT trying to add 500 bolt-ons onto your car. Base first......build from there. Quit guessing, listening to friends, reading FAQs, etc. and research through COBB. Pick up the phone and CALL THEM.....they will tell you the same thing.

Exactly what unabomber said....it's obvious you do NOT know what you're doing so you should not be modding your car in any way shape or form. The map notes says specifically what is acceptable and what is not. It says right in the map notes that headers will most likely decrease boost and power. Research before you start slapping stuff on.

http://www.cobbtuning.com/sti/access...2093%20oct.txt

"If using Headers, be aware that boost response will likely decrease and, depending on the header design, power may actually reduce"

Yes. Read the Cobb instruction manual very carefully and follow the instructions on what to do to unmarry your AP to the letter. Don't skip ahead and be VERY careful.

i will be un marrying it tonight and have the headers off by the end of this weekend. once i get stock headers back on can i run stage 2? would stage 1 be a better decision? i would consider my exhaust turbo back because it is fully catless.


btw why is going back to stock tuning better? if anything i would think that staying on stage 2 map would make it rich and lessen my chance of hurting my motor.

Dude. Catless does not mean Turbo Back. Cobb sells full TBE's that have racing cats in them so catless does NOT equal TBE. Period. You need to read Unibombers Facts on Exhaust at the link below. In fact you need to read each one of those links very carefully before you start modding a car.

Are you seeing the benefits of the AP? Are you having problems? Depending on your answer to that one will answer this statement. You clearly do not understand the basics of engines and how they work. You need to go back to stock tuning until you get your headers off and put on a full TBE (refer to the Exhaust FAQ in Unibombers link and read up). Then you need to look at the map notes for your car on the link I sent you earlier and when you have what's acceptable within the off-the-shelp map for the stage 2 for Cobb's AP, then and only then re-flash to the Stage2 93 map.

Any other questions, you need to contact Cobb.

have u gone to the COBB website to research?

Stage 1 93 oct - STOCK CAR! no intakes, no exhaust...nothing (however, the only intake that will work is a COBB short ram)

Stage 2 93 oct - full 3" TBE, no intakes, stock turbo, stock everything else

if u have anything other than what COBB tells u to have on, ure gonna destroy ure block. if u want to put other mods on ure car, buy streetTUNER, or find a tuner that has proTUNER. they can custom design a map for ure mods. like csewrx said, DONT SKIP AHEAD! FOLLOW INSTRUCTIONS! AP is idiot proof if u research first.

however, if u go back to all the stock equipment, u can load stg 1, so u wouldnt have wasted ure money.

looks like i will be putting my stock headers on, putting the ap to stock and working on getting 3" turbo back.

id like to not have wasted 200 on my midepipe so would getting a axle back system like apexi ws2 or borla hush be good enough even tho they are 2.5. the amount of airflow cannot be that different.

probably not. the system im looking at is a 3" turbo back, and a 2.5 inch axelback. since the axelback is behind the cats and the O2 sensors, it prolly wont hurt nething, but hopefully one of the great scooby gurus can answer it better than i can.
