I recently installed a Perrin FMIC and was wondering what kind of pressure drop everyone with it was experiencing?

I was hitting 23psi and holding it pretty much to redline, but now I hit 23 and it falls to 18.5/19 psi by 8K, is this normal? I really don't think there is any leak, because so little was changed/messed with during the install of the Perrin FMIC.

Thanks

 

Personally, I don't know to be honest with you, but a friend of mine has the Perrin as well, and he has the same problem. I've tried to search and find out results but haven't came up with anything.

 

I don't have that problem with mine but I do have a ebc...

 

try to make a boost leak test when i changed mine out i thought everything was fine but i had boost leak in places would have never imagined when everything was fine the boost was spiking 1psi more and holding much more boost

 

Yeah, but it's hard to accept that considering nothing but half of the LICP, fmic, and couplers were messed with you know? But yeah, a boost leak test is def happening soon.

 

Sounds like you have a boost leak.

 

Are there any other symptoms a car will have when there is a boost leak?
