i dont think it can hold anymore boost than it did before. but i think the average high boost on the vf39 is 17.5psi, because the car will hit fuel cut when it boosts over 17.5. you can get a fuel cut defender, but you would have to be very careful with that, because if you dont know how to use it, it can fk up ur motor.

run it at no more then 17.5 anyway even with a defender, the VF39 runs out of steam at like 6500rpm with stock boost, you dont want to overspin the turbo
