isnt that what i said 1 bar = 14.5 psi. bar = hkpa. i just didnt know what a msp boosted at stock so i assumed that was wrong since he didnt make the connection between .47bars and the corresponding psi. if that is what a stock msp boosts at then your tt is working perfectly. i drive a wrx...
yea...you are correct about the psi being 14.5038 bars. my friend has the same problem with his blitz tt. i dont think its as accurate as a boost gauge. i would look into one of those for reading boost.
