lol.........

when i was in a workshop the other day i heard a guy telling the subaru guy that his car does a sorta "shuddery" thing while the car was using turbo.

the subaru tech said if your not accelerating enough while your car is trying to use turbo, then it will shudder, you need to accelerate hard for your car to be able to use the turbo properly

in other words, if you dont accelerate enough the car will be trying to use turbo but it wont quite work

now i dont know if this is correct - maybe some of the techs on here can clarify or give more to what i said as im not too clear on it either
