Replaced boost solanoid a while ago, gained 60km a tank fuel economy from meter and the car defiantly runs far more consistently.

I found the old one was OKAY though when I lubed it up regularly but got sick with it being 150,000kms old and replaced it, it was defiantly better than ever lubing it up though is the main point so I don't feel ripped off for the $51.

Hi everyone

I've been thinking about doing this but I've got an aftermarket duel stage boost controller and was wondering if it's safe. I'm guessing it's same/same but different and shouldn't cause any problems just thought I'd ask first.

Cheers Dan

Nah don't bother. Boost is controlled electronically by the pcm. Any change to max boost pressure means change to fuel/timing/spark etc

my boost control was getting a bit rough and with 250,000 on the old FG I decided I would pay the $60 and get a new solenoid. The old one seemed to work fine when testing it out of the car (and the actuator was all good and relatively new)

it certainly smoothed things out and bought the actual boost much closer to the desired boost on the laptop log.

easy to change (removed the 4" from the gtx and you can pop it off the bracket with a screw driver) - I also put a better clamp on the outlet as it was way to easy to pull off.

$60 well spent

so it seems even though lubing them up works a treat, geting a new one could be beneficial in the long run? does something wear in them? also I have herd getting beter fuel econamy a fair bit when replacing these, whys that though?

upon inspecting my old one I would sugest finding something better than wd40 to lube it with. I had almost a honey goop in some parts which concurs with what people way about WD40. it is infact a Water Displacement spray not really lubrication. a good light machine oil ould be better.

look here and dont use wd40 if you cna help it.

Water Dispersant formula 40...yeah maybe time to find something more case specific :)
