I have a 2001 3400.

No. You need an HPTuner or a DHP Powertuner to tune your PCM.

There's a million threads about this.

The answer is just no.

You can't chip your car you have to tune the pcm and seeing as you have the ls a good tune wont do much good until after you've done some good mods

I found one for $166. JET

Doesn't matter what you find, if you want your car to work properly you need to tune the PCM, not just get one of those things that waste your money.

Trust us, the answer is still no. Chibi and I gave you the best options.

Bought a Jet - replaced it 2 twice - then sent the 3rd one back for a full refund. Does not tune - does alter - and simply makes alot of things malfunction. Throws codes, each one had one problem or another. With one, car would not start, another one car idled like a bucking bronco, put it in drive and stalled - third one threw camshaft sensor codes and ran like a *POS*. Don't waste your time or money. Jet = Junk

Trewyn15: I saw you recommended those Depo Black Headlamps for our cars - saw a picture of them on a silver Impala. Looked fantastic, I bought the same ones you recommended today - ought to look great on my silver Monte. Thought it was a great recommendation. Glad I saw it.
