looks like it's just a chip that alters your AIT maybe?

These things honestly do not work on our vehicles. I believe you've got the GS430? If you want true performance, look for an extremely good tuner, and someone who can build/fabricate you a Standalone (which will set you back $2k?) The tuning alone should skimp you over to about 50HP (I am not joking, someone took our engine, put it in a boat, put a megasquirt DIY ECU in it, and got about that much more power on some boat dyno). Just be careful as our rods aren't that bulletproof (holding force of the road is different from that of water).

Ding! A full mark answer... These after market "free horse power chip" are pure snake oil. And unless you make mechanical changes to your engine, (i.e new heads, new exhaust, new intake, etc) produce stock like power numbers.

If your car is turbo, S/C or some Diesels then these chips have some promise. But on a Normally Aspirated V8 (or V6) these do nothing but lighten your wallet. Chips like these have been around since the 80's they didn't work then, they don't work now.
