Hi, i install perrin boost tube kit yesterday on 13 evo x mr.
Havnt install my boost gauge yet, but im using bluetooth OBD 2 scan tool read my boost and other info from my cell phone.
its ready from ecu so should be currect infomation right?
it only shows full boost at 8 psi.

i check all coupler and spray with sopy water but, didnt see any bubble..

my mod - AFE intake kit with perrin inlet hose and synapse synchronic DV and perring boost tube kit. stock exhaust system and un tune.

let me know what is wrong my boost... thanks everyone~

 

anybody help me?

 

Get a boost gauge or use EVOscan to see whats actually going on. When you go for a drive, does it feel like it is boosting or not?
