Pretty early in the WM scene. Suspect they had no clear way to monitor post boost IAT's, likely only watching for AFR to change. Researched it to death n was set on using for the Cobra but have since been able to better manage engine heat (huge oil cooler and removed factory version) which in turn has lowered IAT's significantly. Had I installed, would have opted for nozzles below the blower and intercooler. Complicated install but well worth the effort.
One we did the check on, was mearley plumbed into the intake tube with a single nozzle. Simple but worked ok.
Have another friend with one, looking forward to see if his intake tube mounted unit works as well.
