Hey all,
So when I downshift from 2-1, I get some hesitation and it sounds like misfires and anywhere between 6-9* of kr. I also have to fault codes, P1571 (Traction Control Desired Torque Out Of Range) (the abs/traction light is on due to a bad wheel speed sensor) and P1260(Fuel Pump Speed Relay Control Circuit Conditions, k[FONT=Lucida Grande, Verdana, Arial, sans-serif]ey on or engine running, then the PCM detected an improper voltage level on the Fuel Pump Speed Control PWM circuit, condition met for at least 30 seconds). The mods are new(put in today) Al 104's (gapped to .052), 3.4 pulley, overkill tune, headers, 180 tstat. I think the NAPA wires have around 40k miles and the coil packs had a resistance measured around 6k+-0.05.

Thanks,
