oopps, I did forget to mention that without EM upgrade/changes, you are Stage nada. Stage 3 is supposed to be everything but the fuel injectors and the turbo. My car is supposed to be Stage 3, but I really think it is all hype and I am not making enough to the wheels to even bother posting my dyno slip. I have given up on going fast..... can't do it properly w/out a tranny upgrade. I will stick to making it stick.

Just because you dont have EM does not mean you arent or cant be considered a certain stage, or therefore you wouldnt know what stage to choose if possible from the type of EM you are using. If you get a tune (be it road or dyno, but have no EM) you at whats consider a certain stage for mods. Stages also vary a little between which company or user you are looking at. Cobbs is a little different from the Utec, who knows about a Hydra, something like that.

This is what I use for my reference

What do stages mean?

IBA knows his sh*t so that is what I go by.

Nobody should be adjsuting the wastegate unless you are getting boost oscillations or having trouble hitting your targetboost after trying to first tune it out through the ECU.I just want to make sure people are not thinking this is how you get your car to get higher boost without paying for a tune.

Umm, last time I checked getting a tune and EM were basically one in the same. Now, the difference is what EM you are using. Is it a piggyback, stand alone, or OpenSource. You have to have a tune to be considered "Stage X" or else your car isn't going to like you.

As an example, say I install STi pinks and a VF34 but don't change the injector scaling from 420cc to 565cc and do absolutely nothing about the boost maps. My car isn't going to be very happy. Yeah, the parts are there but they aren't being used properly. It's kinda like those stick on hood scoops from Auto Zone.

What all this boils down to is YOU MUST BE TUNED. That's the only concrete rule I've found when it comes to working with these cars. Well, that and Lean = Boom = New motor.

Honestly, I don't typically refer to my car as Stage 4 unless I'm talking with someone who has no clue about bolt-on upgrades. On the other hand, if they do know a little I'll tell them turbo swap, injectors, I/C, etc. If they know Subarus, I'll tell them VF34, pinks, massive TMIC, etc.

Hi. Im currently overboosting to 19.76 pounds at 5000 RPM with my 2002 WRX. It has an OTS Cobb stage 2 93 octane LOW WASTEGATE map. I was having this problem before this map so I flashed to thie LWG map and the problem is still there. Is adjusting the actuator arm(making it longer) something that you would do to rectify the problem Im currently having? Or should I be looking into a new actuator or BCS? I cant afford either, so I want to try this first since its basically free. Thanks in advance.

This is great you guys are great.

So my problem ended up being an error with my acessport, it's cable or the ecu because the 19.76 lbs that showed up was only recorded in one cell of the spreadsheet. Meaning it would have had to have spiked from 14 lbs to 19 and back down to 14 which is impossible lol.

No its not impossible. Its called boost creep. Your car was trying to get to target boost and overshot then corrected itself. I mean... its a little more technical than that but that is basically what happens.

I don't think boost creep happens and then is corrected in 1/100th of a second, which is what my logs say happened. Cobb even confirmed that that's impossible. If our cars were capable of gaining 4 lbs of boost every 1/100th of a second then we would all be dead right now and I'd be VERY disappointed in what hell is like.
