Slow And Smokey Nm35

Lucky it's not dead.

A turbosmart unit on the piping between the FMIC and the TB would be a Blow off Valve rather than a Boost Controller.

The Boost Controller is, in a stock configuration at least, clipped/bolted on the engine block next to the air intake. It has an 'in' and 'out' valve; the 'in' valve plumbs in from a tee piece off the boost line running down the front of the engine towards (and then over down to the turbo), the 'out' valve plumbs in to the back of the intake (at the top, just in front of the aircon [i think..] line). Sound like something you've got?

I don't have a photo of a complete engine bay on hand =/

Drives so much better but should factory boost gauge be way off the scale:-/ But my constant under load stuttering has gone:-) Could someone please post up a pic of factory boost controller piping:-)

Here's one I prepared earlier

Thanks heaps for that ! I had it right ;-) Runs over a bar of boost like that ..

If there is no pressure getting to the wastegate then it will be overboosting. You need to get someone to have a look at it if its not too late already.

[PN-Mad]

Yeah, if unlimited boost, afm maxed out, gone into rich and retard to try to save the motor. You'd want to do a precautionary comp test to make sure the motor hasn't been damaged.

Glad you found it!

1 bar is stock boost.

If it has my HD actuator, it should run 17-19psi.
