Will _______ work with my Cobb Stage X?
Will the Injen intake work with my Cobb Stage X? Yes, for the WRX only and only if you happen to have a copy of their older Injen intake map. With their newer maps, the Injen intake map has been deleted though. It is always a good idea to use the latest maps, so current Injen intake users should strongly consider removing the intake and using the latest map.
Will the _______ intake work with my Cobb Stage X? Yes. But you will have no idea whether your car is now running lean, rich, or inconsistant without data logging and a wideband O2 sensor. So you might have to spend $300 just to find out you should sell your intake. Will the Cobb SF intake work with my Cobb Stage X? Yes, according to Christian at Cobb Tuning. Will the SPT intake work with my Cobb Stage X? No, according to Bill at Cobb Tuning. Will XXX exhaust configuration work with my Cobb Stage 2/2.5? It was designed to work with a catless 3" exhaust, but you can run any other configuration down to a minimum of just a downpipe and be fine. Realize that the further from the specs you go, the more amount of possible less than target boost or power levels you will have. How much of an effect does a 2.5" catted exhaust, just a downpipe, or a frankenstein hodge podge of an exhaust make you lose....no one knows. Will the VF-39 work with my Cobb Stage 2.5? Yes. But you will have no idea whether your car is now running lean, rich, or inconsistant without data logging and a wideband O2 sensor. So you might have to spend $300 just to find out you should sell your turbo. Below are a list of things you can add to your Cobb Stage X: P&P throttle body High flow foam or K&N type air filter Snorkle removal or delete BOV Silicone intercooler hoses Silicone turbo inlet TGV deletes (you'll need a fix for the CEL if applicable) P&P exhaust manifold Headers Lightweight Pulley Bigger TMIC FMIC (this one is kinda shakey as results are a mixed bag, not sure if the FMIC or the associated intake is/was to blame) Walbro fuel pump One step colder spark plugs Catless uppipe Deadbolt Monster P&P turbo (stage 1 or 2) Deadbolt Monster P&P VF30/34 (stage 2.5) Remember though....anything you add to your Cobb Stage X will more than likely NOT give you the results that others who are tuned have seen. So don't think that headers will net you 17 WHP because that's what the manufacturer has on their website. So it's fine to add the mods now and not realize the mods' full potential or add the mods now knowing that soon after you will be getting a custom tune for the full benefits. Cobb's mapping still uses the OEM computer's learning function. This means when you add something new and a parameter changes, you may see some differences either "good" or "bad", but after the learning process of the computer occurs, it will settle everything back out as near to it's original state as it can. This info comes from a long time Cobb user who modified the dog crap out of his WRX and still saw the same WHP numbers as TBE only Stage 2 users. Speaking from experience here: I ran a JDM Ver. 7 TMIC, Borla headers, Perrin Pulley, Vishnu uppipe, fully catless TXS/Prodrive exhaust on a Cobb Stage 2 = normal Stage 2 on the dyno.

I think they did away with the Injen map. I haven't seen it in a while.

Interesting, Cant say I see a point.
Compiling seems to the best step, indeed. *Insert Thums up gremlin here* It's very important to consider the rammifications that a part can make to what makes a tune accurate. Last edited by parker; 03-05-2006 at 12:24 AM. |

Sorry, there is no point to this post really. I mainly made it to refer people to as I see about 2-3 posts a day from people posting in the WRONG FORUMS saying "will headers work with an AccessPort?" and "will my AEM CAI work with an AccessPort?". I'm hoping that by linking to this post and closing the thread, it will stop me from going off on them to search or (OMG, no way!) actually visit Cobb's website and read the damn manual.

i have a quick questio. you said above, unabomber, that you added "JDM Ver. 7 TMIC, Borla headers, Perrin Pulley, Vishnu uppipe, fully catless TXS/Prodrive exhaust" to your cobb stage 2 but do you mean you just added it to the stock maps that cobb offers with the accessport?? i feel dumb but you said cobb stage x map and i went on there site and didnt find an X map. Unless you simply ment like adding that to a basic map (as in X = a basic cobb map)??

X = stage 1, 2, or 2.5.
I added those mods to the Stage 2 map and as well used the Stage 2 HWG map. |

Here's a better idea... stop using Cobb's OTS maps and go with PDX's if you must run an OTS map. They are much better. Take a look at the logs from everyone with PDX OTS maps and then look at the logs of people with Cobb OTS maps. You will see the differences.

What would be the effect of Borla header on VF34 equipped WRX on a OTS Cobb 2.5 map? Do I need a custom tune?
EDIT: just got a response from Cobb (Christian) that THEY do not recommend aftermarket header on any of their maps due to inconsistency in performance. |

Haven't heard back yet... hopefully I will. Until them... I'm stuck with OTS maps. There is no one in my state that does tuning, so I'm all alone. |

Well with headers being said and I just found this sticky...I will add my headers (knowing I won't use to full spec) to my stage 2.5 setup, work on suspension mods and then get a protune...or something like that
-Joe ps- Will need quieter exhaust though. |

Say what you like buddy, but TBE only equipped Cobb Stage 2 cars where putting out my same WHP/TQ on the same day on the same dyno at the same dyno event at Mach V in Northern Virginia as me with the above mods + Cobb Stage 2. Believe when I say.....been there, done that, got the T-shirt to prove it.

scientific method and true controlled environments are impractical with modification testing. car to car is better than anything else. otherwise the testing would have to take place over a course of about a week.

With regards to that list of mods with no more gain just Stage 2 Cobb stuff - -
I personally think the only thing the WRX needs is a turbo...especially true for the 06's...then of course some more aggressive maps to use it... Headers and intakes and exhausts are generally pretty good stock when it comes to most performance oriented cars... You can spend 450 bucks on a TRD header for an AE86...but you don't need one unless you have over 200 HP (not feasible).... Plus, maybe it's not the peak power, but how long it takes to get there... |
