Celica Performance chip, What is it?? Options

I read that someone has a celica performance chip; i've never heard of it before. What does it do?

I just got the Jet Performance Chip upgrade and couldn't be happier. The thing about this upgrade is that you do it as your last upgrade outside of nitrous. When you send your chip in, you give them a list of your upgrades, and the taylor the chip to that. I got about 15 wheel HP. Right off the bat it was the best upgrade I've done - BAR NONE. Better than my intake and custom exhaust combined. The Venum 400 has gotten terrible reviews and will reduce your gas milage by at least 2-3 mpg. There is one bad thing about my upgrade. You have to mail your ECU in, and i couldn't afford to be without my car for the four days it took (I sent it in 2 day, they return it overnight) so I bought an ECU from a junk yard and tested it for a week to make sure it worked. Jet said that because it was not the "origional" ECU there would be no warranty. I said go ahead and do it. I can run 89 octane with no problem and my gas milage is the same as it was before (even though I floor my car quite a bit more now). I paid $380 for the upgrade and $100 for the second ECU. They even said I could run up to a 40 shot of nitrous with it without having to retard the timing! That is what I plan on doing next. Hope this post was a help.
