i beleive its a tial replica. i brought it with a 0.5bar spring that will only boost 4psi
ive tried turning up using my forge boost controller but the max boost i can get is 10psi no matter what i do so think maybe im asking too much of the crappy spring they sent me
i have a tial, and it boosts 0.7-0.8 bar with the stock spring and boost controller off. With the boost controller i can boost up to 1.7 bar. maybe you ve setup the vacuum hoses wrong?
