Also have a question keith I seem to have a high pitched squeal coming on boost at around 4000rpm, sounds boost related ive had to cable tie my bottom intercooler hose because its been a *beep* and dropped below my bar can something like that affect boost noise if its pinched in about 8cm. Cheers brother.

So tonight I brought the factory blow off valve to replace the stupid blocked off sh*t the previous owner had done I was hoping u could shed some light on where to find the vacuum line that goes into the top of the bov.

blocked off BOV, FTW!

but since you don't like it, the vacuum hose will come off a t-piece at the back of the plenum.

it's hardly any lost boost if you're up it... it's manual vs auto that loses more boost (manual does) on gear changes... the idea of a BOV is to throw away all unused boost when you get stop accelerating, so I don't know what you want from it. :idunno:

 

Not sure why you'd think a dose sounds like "guna stall" but it sounds like your car has a different problem if it does actually make the car come close to stalling.

 

but if you don't like the sound itself, that's fine.

and have a hobbs switch to get rid of spark during hte change to allow for flat shifting and the associated gearset to be able to flat shift without doing much damage? yep.
