I just purchased HP Tuners and am looking to get some stuff in order before it arrives. Can someone tell me or lead me in the right direction as how to tune my 5.7 Vortec with a LT4 Hot Cam? I originally did a mail order tune and it doesn't want to idle right and doesn't have anywhere near the power it should.
I really don't know what all I should change in order to adjust for the cam.
