10-5,6-10 woes
 

Hi all.

I got this car 10 months ago and pretty sure it had 10-8-10 after replacing couplers and securing some vacuum lines but now it's 10-5,6-10. Down pipe is the only mod. Pulls 19 vacuum. Searched but couldnt find any definitive suggestion.

Any help as to where to check is appreciated.

Thanks

I highly recommend you double checking your vac lines again.

Yes. I think I'll need to replace them all but wouldn't a vacuum leak affect boost across and board?

Sorry, I meant double check to make sure it is routed correctly.

I didn't change the lines. Only secured ones that were really readily assessable.

Something is plumbed wrong during the work you did, or you have an intermittent boost leak now, due to something you worked on.

There's not going to be any super detailed information other than go back over what you did, try to find the leak or find what you may have plumbed incorrectly.

Nobody is going to be able to say "Oh you routed the small vacuum line X onto Y barb by accident, and your leaking boost from coupler Z" over the internet, unfortunately.
