Limited boost -10 psi

[falcon8r]

My talon is back together after replacing the entire exhaust system. Got an FP manifold, ported s16g, EVOIII o2, 3" dynomax I built with no cat. That car never had a real boost gauge. I installed an AEM truboost but the sol is bad. I get an SWS error code. So it tried to by pass the wastedgate using the stock EBC and still only 10 psi at 6500 rpm. I made the output tube on my fabbed J tube out of the top of the 16g. Is the tube -3 size too big and I get too much volume (CFM) of air going to the boost control and it can't handle it? Back many years ago my mustang SVO had a way to drill all the little orifices on the W/G control to run a constant 20 psi. I put a plastic "T" in the loop now with a restriction in the feed from the J tube. I have not driven it yet. Doesn't the 16g have a 12 or 14 psi spring stock??? Tres....

I am at loss here, explain yourself a little better. Are you saying you can only hold 10 psi ?
I hold 12 psi in 1st and 2nd gear rolls before creeping and 10 psi on the rest of my gears.

Yes ,that is correct. It barely hits 10 psi at all. Solid in the 9psi range creeping to 10 sometimes. The car revs much better than before I should add. Tres....

You should be happy it stays at 9-10 all the time, boost creep really sucks.
Do you still have your catalytic converter ?

No, it is 3" with a Pypes resonater and a dynomax muffler. I just drove the car with a restriction in the feed line and the stock EBC hooked up. It now goes to around 14.9 psi and goes quite a bit better now. First gear is almost unusable now. I do have my small tires, snow tires on the car now. It is a total sleeper. Tres....

nice 14 psi is good to me

If it holds 14.9 all the way without creeping then it sounds good enough. Just make sure it doesn't pass that.
