I think we got the graph data wrong for the 20g. Its fixed now.

16 psi made tons and tons of power.... we kept the boost low to protect the longevity of the stock motor and transmission.

The early torque on the Legacy looks impressive. Is this a model with the low mount turbo? To what hp does that particular turbo flow with an exhaust and adequate intercooler?
