Ah ok, might go with a Devilsown kit when I do need to go with WMI, did you go with a single point injection or are you going to run 4 nozzles in the intake manifold?
TBH the AEM kit is all you'd ever want for the money, both Alex and myself are running AEM - though Alex's is the older version so is physically slightly smaller.
I'd go for whichever has the best reviews recently.
