Where should i start with jetting?

[LS1Inferno]

I got the 87 fixed(5th gears was stuck) and i got some FMF gold series pipes, with power core 2 silencers. It has TORS eliminator. Where should i start with jetting, i live in las vegas which is like 2000 feet

 

EDIT: everything else is stock.

Stock air filter with lid? If so, start around 270 like sheerider said and visit FASTOYS on here, he has a link to a plugchop in his signature that will help you out immensely!!!!!!

Yep EVERYTHING else is stock(for now). Ill se what i can do about the jets. It seems fine, The FMF website says starts with the 260 and the needle in the 3rd position i dont know what its at know. Thanks for your input.

Especially if you are going to do other mods, you will benefit greatly from doing a proper plug chop. It is the best way to tell if you are jetted correctly and all it costs is 5 bucks for a set of plugs to wreck. I went from stock 200's to 330's with my fmf's and a K&N without the lid. I stuck 300's in off the bat and it screamed but if I hadn't done a plug chop my motor would have siezed in no time. It also ran better getting the correct amount of fuel, go figure!
