...and the modding begins. Just bought LTs, ORY, o2 sims and a crapmaster Super 40 with a turndown. Thanks to Sean at Speed engineering for a good price.

just an FYI, if you don't already know, o2 sims are not being produced anymore...so grab em if you can.

Whats A O2 Sim

I just turn off the SES code for the rear o2 sensors being in the trash can instead of on my truck. It saves about half a pound on a 5600 lb truck. I'm all above saving weight.

Nice mods, post up your results.

no need for 02 shims if you know how to tune or have access to a tune

SSSBLKOUT

It tells the computer that the rear O2's are reading the proper amount of oxygen in the exhaust after passing through the cats. You need them (or a tune to delete the code all together) when you remove the cats.

I wish I had the software (or the confidence to try and tune it myself). You know anyone on Long Island, or lower NY that can tune it for a case of beer, if so, let me know.

i'm sure you could get a dyno tune. go over to the eastern section of LS1Tech and ask there.

SSSBLKOUT

Yeah, I thought of that, but its gonna cost more than the sims did, and I am not really looking to go crazy. Little perf. boost and a nasty sound, I'm happy.

Hell, I still have the stock airbox.

so do i...along with alot of other guys...whats that have to do with anything

SSSBLKOUT

I was just hinting toward the lack of motivation for performance, thats all...although I might cut a hole in it for some more air...

Whats the story with the mail order tunes? I got one done for my lt1 z28 a few years ago, but it only netted 8rwhp and I had IAC issues after that.
