Does the Venom 400 Chip really work, and has anyone noticed a difference with it?

Well, I just got my Venom 400 today for $150 used and installed it, minus good instructions. Concidering that I installed it correctly (can someone conferm that the orange wire goes to the map sensor?), the thing seems to be working correctly. EXCEPT, I got a CEL when I started up my car. My first though after I installed it and reved my engine a few times was, "wow, it kind of smells like gas," but after reving a little more the smell went away. I took the Celica out for a test drive and I can DEFINATELY feel a difference. I would probably guess around 5-10 hp gain, honestly. I did the CAI and muffler, and I'd say that this thing gave me more gains than either of those, especially in midrange rmps. Negatives: the thing was a bitch to install with no dirrections other than what was on the venom site, and drilling through the firewall is never exactly fun. My CEL is still on, and I'm probably getting worse milage, but thats ok because I was getting about 30mpg before.
Overall, I'd say that the chip is NOT worth the $400 msrp, but is definately worth the $150 i spent. If you don't know how to read a wiring diagram, you probably wont be able to install it yourself. I really want to go to the tracts or something and try a run with it on, then one with it off. So yes it works, but not for the 25% hp that they claim.
