I went to Courtenay today for the CS4 upgrade. I left my house 4.30am to get there for 8.30 and didnt leave there until 7pm with other 4 hour drive home.
Great buch of guys at Courtenay and I have no complaints
end result was
287.6 @ 5635rpm Bhp
329.7 @ 3580rpm Torque
it pulls like a train and foot down in 5th @ 80mph is just mad with it hitting 24psi
