i got a K&N intake a catback exhaust and stage 1 and when i get on my car the boost gauge reads almost 15lbs of boost does this seem right

 

no you should be around 12-13 but maybe your boost gague is off or your cat is clogged.

 

well lets see here i have a 310 pully and a injen intake and a flowmaster muffler and im makeing 15 16 psi on stock injectors. so if the pully still stock than yea i guess that would be right

 

our cars boost 12-12.5 STOCK

 

Keep in mind the stock boost gauge is electronic so being inaccurate is not uncommon. On my stage 2 I saw 14 lbs of boost and with a mechanical gauge I saw 16-17. I've also noticed temperature can affect how much boost it will show. If you were truly curious you could put a t-bracket into some vac line and run a mechanical gauge for a day or just switch to one altogether.

 

As said the gauge is crap and a clogged cat will cause this also.

On the mechanical gauge... is there a good way to stop the "buzz" completely. I had an autometer in my Passat and for the first 10k miles it was fine then all of a sudden one day it started buzzing, very annoying.

 

how do i know if my cat is clogged

 

I think I might be experiencing this buzzing noise too...only certain times, when I accelerate it will sound almost like a ringing noise, like a small bell. It is very annoying...it started right after I put the mechanical one in, so I figured it was related. I was going to try and look at it this weekend and see if I could figure out what the deal was...

 

electric/digital > mechanical

 

Antibuzz fitting

That T-fitting has a restrictor in it that will help eliminate the buzz.

 

I'll post a log tonight... stock pulley, injectors, tuned with intake hit 14.88 psi.... (not cat either)

 

Awesome, thanks. I was reading up on this today and found a similar product someone else was selling for $20. I sent Autometer an email, hoping they might have something like it for cheaper. I might just go ahead an order this one. Seems like it will fix the problem...

Thanks again! +rep

 

okay i got a questionn...on our stock boost gauges...where should the need be at WOT on a STOCK car...1-2 lines before 15psi?

 

Honestly you could build this from Home depot tubing for pretty cheap too. take a piece of plastic tubing with an outer diameter that matches the inner diameter of your t-fitting and has a small inner diameter like 1/8 or 1/16 and cut a small piece and glue it into your t-fitting on the side where your gauge line hooks up.

 

Want to buy a Mech boost gauge??
