SnowManZ
18:02:56 02/08/06
That all depends on how worn out the turbos are.
-
Ash's Z
18:10:58 02/08/06
Well, it isn't isolated to just stockers or sport500s.

I think it has to do with age, condition of the seals.

Spee
16:40:47 02/08/06
Some of them do need backpressure to work properly.

SnowManZ
