Boost controller, I would say is no good and you should sell it. Our cars do NOT like those and you will destroy your engine eventually with one. Sorry.

Save the environment or ill f***ing kill you!

the problem with the maual boost control on your set up is that , you never know how much your car is going to react to the slightest adjustment of the boost controller. you might turn it a 1/4 turn and get a 3 psi reaction. if that happens , say goodbye to your engine.
I say , if you have a maf sensor in a subaru , don't mess with manual boost controllers unless you are a tuner , have a tuner that checks your tune after every fill up, or have a lot of cash to repair your car.
Besides, just turning up the boost on your car with those mods will probably make you slower, the ecu will compensate by retarding the timing.

it definatly stands out. most people would say its ricer but i like it, probably the only aftermarket paint that i do like. its not an annoying color combo the two greens go together really nice.

i am gonna give you a !Thumbs Down on the interior though IMO
call me a ricer but on your car.

I'm confused. Why would you use a boost control if you have a UTEC? As long as you have the correct map/tune, you should be fine. You can use UTEC's ABC to control the boost. Stick to 17psi. Stock turbo maxes out around there, and your injectors aren't too far from it either.

I concur with the injectors maxing out but not the turbo.There is a td04-13T compressor map i have a link to somewhere on this forum.I run 20psi in the midrange and some up to 22psi with supporting fuel and I.C. Tapers very quickly to 15psi by 6500rpm.Its pushing things alittle but i have worked my way up slowly and have 100K on the motor so its had a good life! But you need to be tuned for it.If you can access your map i doubt the fuel and timing are scaled for to much higher a load.

General consensus is that over 17psi, you turbo starts to blow air too hot to be effective. But, I suppose if you had time to play with it, you could make it work. Most people don't have that patience or desire to max out the TD04, unless they're doing sanctioned racing with certain rules.

That was just speculation because no one had a compressor map for the 13T.Hell for a while everyone thought the WRX had a 13G.http://forums.nasioc.com/forums/show...compressor+map
