hello recently i have been seeing boost numbers peaking at 31 as before when i had my smarty jr i was peaking at 38 and with my XZT 40psi. my question is after i upgraded my XZT i was boosting 30 at a max and 35 without the XZT. Now i have a bullydog and im only seeing 31 once again. Anyone have any ideas. I dont think I have a leak due to 35psi when stock. Also this is an analog gauge.

 

Do you have a boost fooler?

 

i just recieved a boost fooler today and after testing i only reached 35psi. Any ideas?

 

Make sure you have your gauge air line compression fitting tight, make sure it ain't leaking. Check for any boost leaks also..
