i have an 06 sti stage 2 and protuned. mods: tbe, aem cai, fuel pump, hallman mbc, and accessport v2.



I went to stock and am about to put my parts back on, but realized i accidently turned/touched the mbc which adjusted it when taking it off! How do i chek to see if i am at the right psi? (im suppose to be at 18psi.)



Please help and answer ASAP i really don't want to be hurting my car by over boosting or underboosting on my tuned map. thank you.

 

do you have a boost gauge?

 

yes i do the stock one. but donno how to read it. im at 18psi for my tune. i think it's close to the .1, but not sure if that is 18psi. i heard maybe u can read it on the data log from the accessport, but not sure never tried that.

 

you should be able to do it with the acessport just plug it up and have it read live boost. or you can take a look at this

.1 MPa = 14.5psi so if your at .1 on your stock boost then your at 14.5psi

 

check from the ap or go see Ed at eq tuning

 

hey, did you use the light spring or the heavy one in your Hallman kit?
