My VR4 is a prick, im sure it hates me
I bought a broken down galant, wasnt running at all when purchased, motor is a 6a12tt
I have worked on her for around 2 months, i have replaced all sorts of bits..
The problem is i build no boost (i beleive) and it wont idle past the 6000 mark, it starts bouncing and blowing smoke, Idle was dodgy but i replaced the air flow sensor, and got new piping, i have also replaced the vacume lines,
What in the world would stop a galant from reving right out, i can drive it normally but i dont feel any boost
I have a boost guage and bought the car with all sorts of dodgy crap done, i have been sort it all out, bit by bit
My VR4 is a prick, im sure it hates me

One of the first "free" mods DSMers did back in the day was to hook up the boost source nipple directly to the WG actuator, that way it bypasses the solenoid. (it is good for low boost).
I think u need to understand how turbos work bud. The solenoid raises boost by bleeding pressure to trick the wastegate into opening later creating more boost/psi. If u bypass the solenoid u run base wastegate pressure of 7psi. And because we have 2 turbos it doesn't make 14 psi. They still only push 7psi
