On what motor?
b18c SiR motor
When you get a boost controller it will fix this. It will allow you to bring the boost on earlier.
Before EBC full boost didn't hit till close to 5000RPM's

EBC Installed now full boost kicks in a bit before 4500RPM's

And that's with my crap bushed turbo..
Your ball bearing turbo should spool even faster...
Post some dyno's?
Yep get a boost controiler.
I have same setup, GT28RS on a jap B18C running Autronic SM4 with optional boost control solenoid.
I get my full 8psi at 2700rpm, not kidding!
Currently got 2.5" mandrel from turbo to high flow cat, and 2.25" crappy crush bent from then on.
Going to upgrade soon.
ive got 3 inch from the dump pipe all the way back to an apexi n1 muffler.
i will be getting Eboost2 i think shortly, but then you have to get a full retune so it may be a little while...
how much power r u making mooshie?
See my thread- 'another DA9 turbo'. 157 at the wheels currently.
with my eboost my car get full boost at about 3.5k, b16 with GT28R@162kwATW.
That's why i told luke earlier on to get one :)
