and if you call they will most likely tell you it's not actually in stock... I found a few sites that claimed they had the TRD supercharger, none actually had them. The Magnuson is the only way to go at this point unless you manage to find a TRD version on ebay or craigslist. I couldn't find one, so I got the magnuson version, it's identical except for the TRD logo's, comes with everything you need, in the middle of installing it now actually. Infact it is actually a more complete kit as it comes with a bullydog GT Platinum that it uses to do the ECU updates.
