ok hes the deal i had the hks that comes with the fmax kit, well i wanted a louder one so i got the blitz. Well it sounds the same, sounds like a flutter and a sneeze. Is the something ive done wrong? any suggestions? TIA

 

How many lbs are you boosting? At lower boost levels the Blitz flutters a bit.

 

use a different vacuum source....I had it happened before, then I move the Tee as close as I can to the vacuum source..it works like a charm

 

Where would be the best plase to tie it in?

 

Maybe I should try that as well. worth a shot

 

haha for some reason i read the topic as "boy problems"

 

LOL!

 

try to do it closer to the intake manifold and with less vaccum output

 

Sorry if this sounds stupid but what ya mean with less vaccum output

 

I tried not to tee more than 3 vacuum output out of a single source, for example, I tried not to put boost gauge, WG, FMU, BOV, and etc in one single source..

I had fmu, WG, and EBC from the FPR
then I had Boost gauge, EBC vacuum source(AVC-R), BOV on the evap purge

and I tried to tee it off as close as I can to the inake manifodl

 

less vacuum input.... meaning dont share the vac line with anything else except what was there originally and the bov. Hmmmm like find a vac line, T it, and the only thing u connect is for use with the bov ONLY. lots of em behind the intake manifold.

 

oh and trim all your vac lines to the MINIMUM length. no loose lines.

 

I have all three of my vac lines coming from one source, matter of fact all 4. fpr, WG, BOV, and FMU...it is working ok for the time being. But you say there are more behind the intake mani? I swear I looked and didnt see any....oh well worth another shot

 

on your hood there;s a vacuum diagram from the factory , just folow it and yeah, no loose lines. keep it short

 

I'm a sohc'er though. It may be different for your application. I use one in the back of my manifold strictly for the bov.

 

one for the wastegate? i dont have one for that, but i have a manual boost controller is that the reason?thanks
