So when i first got my car it ran a boost pattern of 12-10-12. Over the last few days it started doing a 10-8-8 pattern,. Heres my list of mods

Reman 13b with street port
dp, mp, highflow cat, catback
apexi pfc
m2 air box
mazdaspeed radiator
greddy hard pipes for intercooler
silicone vaccuum hoses


any ideas?

 

Vac line probably came loose somewhere.

 

that was my thought, but when i searched, missing vac lines tended to do a 14-5-5 pattern or a 7-7-7 pattern so i wasnt sure if a vac line could be causing a 10-8-8 pattern or not.

 

A loose line could definitely do that. Especially if it's just cut slightly or loose but not completely off the nipple.

 

k thanks a ton, time to start the hunt
