yep, that's the way it works.Nelson Peformance sells them for $50 or so and you can have them throw a tune in it at the same time. Get VATS/Passkey disabled while he's tuning it.

then i reckon the OP needs to be changed...
anyway, i guess i'll have to talk to my tuner tomorrow - he's already tuned my last engine & does free updates as well, so i'd rather not have to pay for another tune because i'm already spending borrowed money...

and hey its always better to spend someone elses money, just suck u have to pay it back...
yep. black box with 4 connectors. 99 was a real bastard year for these trucks...
i reckon i gotta find a mounting box, too because the old one won't hold a 411 - i already tried last month

I wonder if your truck was a Mexican import. A lot of the left over junk get put into the ones they intend to stay in Mexico. You also may just have one of the very first NBS V6 trucks imported into the US that they put the old leftovers into.

Ummm....was it a V6? Then it had the 4-connector PCM like all the rest of the 1999's I rememeber.
mexican??... really??actually - i do remember seeing something about some 99 NBSs getting Vortec 5.7s down there. i actually considered doing that swap myself, but i'd've had to find a 99 or 00 OBS to pull it out of.
actually, my truck is definitely American & was was built in the last half of the 99 run - february actually. i know it's American from the VIN. 1GTEK14W2XZxxxxxx
1=made in the USA, Z=assembled in Fremont, CA
yeppers... that's why it's in this thread
ps - that's the W in the VIN... but of course you know that

Yeah but I didn't take the time to read the other seven pages over again.
just a little tidbit of info...
found out today that (at least for 01 model 4.8/5.3) the 4l60 flexplate bolts & nv3500 flywheel bolts are, in fact, the same. they're also $3.xx each if you're unfortunate enough to have to buy new ones
