adjusting the actuator & worn actuator symtoms
 

Hi bascially i had my car on the rollars recently & it wasnt hitting the right amount of boost i should be 16.5 psi but i was only getting 13psi, i was advised to tighten the actuator 2 turns which i did it & it felt alot better alot more responsive low down felt lifeless before & was also showing more boost not hitting the fuelcut, but today it seems back to how it was again & the boost seems to of dropped slightly & the low down pull is not how it was after adjusting the actuator, any ideas please?
