Im running an xp cam with ported heads, full size intercooler, sd headers, N* tb/maf, 42.5 lb injectors and a built transmission.
how much kr is normal at a wot pull right before a 2 to 3 shift? Im chasing some kr, I went from a 3.0 pulley and 12* of timing at wot to a 3.25" pulley and 17* of timing, and with the 3.25 I had 3.3* of kr at full throttle right before the shift. I heard someplace the blue LS6 valve springs were less effective, and so I'm wondering if they are causing the kr the car shifted at 6327 rpms.
maybe torque management is kicking in?
