I have 2003 usdm evo8.
my car is maped for 1,35 bar boost and falls down to 1,25bar.
everything is original, only upgraded fuelpump , 3" downpipe back exhaust system and lower ic pipe.
i need some more boost. I removed the pill from near boost control valve, but nothing much happened. i adjusted the wg actuator bar and i have only 1,4 bar peak. Is there anything what i have to do?

Change your EVO VIII BOV for an EVO IV or an aftermarket one. The plastic Evo VIII BOV doesn't like to hold much past 20psi

Upgrade your hamster wheel to a smaller one.

How about a boost controller?? and a tune. You can't just crank it up and hope for the best. You will go through parts like crazy(headgasket,etc.)

Yes I also thought the BOV, because there is allways the same boost. i tryed with mbc, but nothing changed.

i dont want just adjust and crank it up. i logging and i have wbo, boost gauge.
the other thing, i dont want nothing extreme. i need this only for few weeks, until i get my standalone. i dont like this dark side in ecuflash.

the mbc arent very sensitive you have to get a few cranks in before youll see anymore boost, so you prob didnt trubo enough... thats how your gonna get more boost plain and simple

Get a hallman pro manual boost controller and a tune and an upgraded bov (preferably a IX bov).

i dont want to do anything else, because my standalone ecu is waiting for installation. it has boost control. this small amount power is need only for few weeks.
