Hello everyone, just wanted to know if anyone around FT Drum is willing to help me out with a stg 1-2 reflash for my 2012car wrx wagon?
After looking into a few threads does anyone know if its possible to run a stg 2 on the new 2011+ cars w/o any added mods given its dual exhaust and good stock air box?
Just figured id ask and know if i need to get a dp or cbe or something
You'll need an aftermarket downpipe to use any Stage 2 map. The cat back and air box have nothing to do with it - the issue is the restriction of the stock downpipe immediately after the turbo. The stock downpipe is basically a flat plate with a hole cut in it, whereas aftermarket downpipes are typically some variation of a bellmouth that tapers to a larger diameter pipe.
I knew about the dp but ive also heard of several people runing a stage 2 setup.
all i want is to run closea to if not a 17psi tune on whatever stage map i can run without a dp change. Is it possible to port anything to compensate for the restriction of the dp or do i just need to eliminate the plate on the stock dp to improve flow?
A Stage 2 power setup consists of an aftermarket downpipe and a "Stage 2" ecu reflash. You wouldn't want to use a Stage 2 map on a car with a stock downpipe.
You could get protuned with your stock downpipe on, but you probably wouldn't be able to crank the boost up terribly high. Why are you so concerned with keeping the stock downpipe on?
I haven't heard of anybody altering their stock downpipe to increase flow. You could probably grind just a tiny bit of material from the opening or cut out one or both cats, but any gains would really be pretty negligible. There are a variety of aftermarket downpipes available and plenty of different ways to get them inexpensively if that's a concern. Almost every aftermarket downpipe will be lighter in weight and flow more air.
Yeah money isnt as freely available these days given a new baby for what money i did have i bought a tactirx openport 2.0 and im rather good at tuning a car not just staging a car, but i also have a lot of small pieces of exhaust pipe sitting around and figured taking out the restriction from the dp would make my day easier than buying a $200+ dp and that i can do myself. So whats my max boost on the stock dp until i can modify it in a few weeks
