4th to 5th secondary turbo transition is slow?
 
Was just testing boost patterns last night, once the car was warmed up everything seemed pretty normal. I just noticed there was hesitation in the boost transition from primary to secondary when shifting hard from 4th to 5th... In 5th I would be stuck around 4k rpms and it would just sit there for a few seconds and then once I reached 4500 secondary kicked in.. On my first few runs with the Double throttle hose hooked up I would spike to ~15psi... When i unhooked the double throttle hose it would stay at 12-13 once secondary came on...

Could this be a symptom of a certain drive belt being to tight? or is this just normal with turbo cars and "turbolag" ?

Also when the car is not completely heated up when i accelerate smoothly i can only get 5psi and I hear a weird sound (this was when double throttle hose was hookedup).. I unhooked the Double Throttle hose that goes into the actuator i did not hear this noise.
