is it equivalent to the nnbs/tbss?
i just installed mine today replacing a 02 normal pickup intake....i dont have any dyno or track times but my OLSD tune is pretty dead on so i imagine if theres power ill see the difference in my tune. im installing my coilovers today also so as soon as thats done ill be able to go for a ride.
I just installed mine this morning, from a 3 bolt early truck intake the fuel rail mount height is taller, and the bolts that go to the head are taller, but you can just cut the rubber isolators off your old bolts and they will work. they are still a little wrong on size but they seem to work. i had lost about half the original ones.
the tb i used was a $90 ebay dbw 102mm one.

pop that silver bent tube thing out and throw a 1/8 npt plug in its place and its ready to rock. all your sensors off the old tb go right on.
i got to drive it a little yesterday, it seems the off idle torque is better, throttle response is a little stronger, certain areas of cruise got rich so it seems to be more efficient. unfortunately i never retuned when i went twins and my boost tables arent quite as good as my drive-around areas of the tune so i wont have as good of a comparison based on tune change, but ill run it up today and see how it feels.
this is all seat of the pants with no data to back it up, but im fairly happy with the swap.
im very curious how this intake stacks up to the tbss intake.

that IS just a NNBS intake- you can tell by the MAP placement up front, as opposed to towards rear- also as mentioned it has no hole for EVAP purge, but rather a nipple for the hose that connects to the NNBS purge solenoid that attaches to the fuel rail. its def just a normal NNBS cathedral intake. BUT none-the-less still a decent upgrade for NBS truck guys! you just didnt find an anomaly 
sorry 
sorry

sorry externally they look quite a bit different.
