quicksilver, I don't think you understand, the new design of the AEM Shorty has the MAF built into the pipe (ie, removed from the factory housing), just like the Cold-air AEM.
I was dissapointed to find this out, as one of the reasons I bought the Shorty was to later add a larger MAF.
I don't think that it is possible to use an aftermarket MAF with this design, because the MAF is calibrated to the size of the pipe.
If someone out there has used one with the cold-air AEM then it would be possible to use the same procedure with the Shorty. Has anyone been able to do this?
