If I'm not mistaken, replacing the stock snorkel with a 3in PVC pipe basically is the Gotts mod. So, not sure how it is you own version, but regardless, it works. That exactly what I did to mine. Whether or not you'll notice any kind of performance is up in the air, but hey, it's cheap so why not right?

I haven't driven it yet so I'll let you know on the any difference, I said my version because everyone I've seen there using fernco's and stuff like that but I used thick wall pipe so all I had to do is put the pipe in....

It is pretty free flowing except right at the intake spot where it narrows down so much. Its creates a big choke point at the spot you need air the most. The Gotts mod I don't think would add 13hp but does certainly improve the running of the truck.

I did the GOTTS mod last summer. 13hp? No way. More responsive and a little less starved above 3500rpm? Sure.

I've heard that the JLA RAI kit for these truck can add more power, and better performance in the upper RPM range as well. Wondering how true this is.

I did this last summer except I used a piece of 4" ABS corrugated drain pipe and a snap adapter. Did not gain any mileage or performance. The only gain we'd get with this mod is at near or at WOT when the engine needs air. Engine sounds a little better though.

Yeah I just did this mod today using the same method you did. I drove it and at about 45 mph to 60 passing someone it seemed to pick up a lot better, and it did seem a touch more responsive.
