Its actually closer to a full standalone than a piggyback, but it has the advantages of both.. hence the reason I chose it..

Yes, I had it installed for about 2 weeks, but as a DRAWTHROUGH setup, which means I installed it in place of my maf sensor instead of putting it into the upper pipe.. I did it to see how well it works, and to be honest, if it were calibrated for drawthrough over blowthrough, it would work perfectly.. I have not yet put it in my upper pipe, I needed a new upper pipe made up, but the one I wanted the manufacturer was reluctant to modify a new pipe for me and send it out, they wanted me to mark my pipe and send it back, but I repeatedly told them it wasn't an option since I drive the car, and gave them exact measurements.. So I'm going to try to find a local shop on the island with a decent flaring/beading tool and cut the pipe and have them put the bead to hold it on...

I wish I had done this sooner, I wasted a few weeks trying to find a shop to make up a new pipe for me.. I wanted basically a buschur short-route upper intercooler pipe with it modified to fit the MAF.. So I'll have more to say about it in about 2 weeks when I can get down to a shop and have my car out of commission for 2 days.
