Mainstream Tuned Bolt on WRX

As you can see the boost is very fluttery and unstable, with stable boost, this car could have made much greater/smoother power.

Ecuflash and stock boost control hardware is capable of a perfectly stable "non-fluttery" boost curve. There is no hardware change required to make a PERFECTLY smooth curve. It will of course drop up top, but it should be perfectly smooth with no waves.

I think you keep skipping over the part where I stated, we did not use the boost control option, as we where still trying to figure everything out with the software. But thanks for the love!

Boo, They are the only ones who know about Subaru's. Kind of like you guys are the only ones who know about Honda's

I am so kidding, kind of

I figured Oh well, guess the more subys we tune the more official we will be. lol.

Naw. You will always just be the less expensive alternative. I am being totally honest. Subaru owners are a eclectic crowd. They have been hypnotized by the all mighty one somehow. Divine intervention, I think. According to Dan, Subaru's are one of the easiest to tune, but they have somehow been convinced it is black magic.

the baseline was exactly the same. that's how it was stock before even connecting the laptop to the car on the stock ecu. adjustments to the boost options yeilded no difference. i wasn't concerned w/ the small flutters throughout the powerband because they aren't that great (it looks exaggerated because of the scaling on the graph. if it were there would be large waves in the hp/tq curve, which there weren't. i was more concerned w/ the boost falling off top which is related to too large an fmic for this particular setup.
