Reduced Power mode?? I've just installed a set of LG LT's and a Corsa indy catback, I didn't bother with the O2 sims because I am going to have the car tuned shortly.
My question is, my check engine light came on after the install and I want to know if the computer has gone into reduced power mode or if it's just throwing the code because it looks like the cats (going to be a track car, cats are gone) aren't doing there job (way high O2 readings)?
Any computer brains out there help me out.
thanks

You are fine..... if it was in reduced power it would tell you on the DIC as well as definately tell something is up. Off topic but how well do you like the sound with your new set up? I'm contemplating switching to Corsa also.

When the C5 goes into reduced engine power mode you'll know it because the car will only move at something like 5mph, and when you put your foot on the gas it will have the acceleration of a 1962 VW Beetle with two of it's spark plug wires removed. 
Like the other had said, you'd know it when your in reduced engine power mode. It'll tell you on the DIC in front of you. Once this happens,...you'd have little throttle control, if any. For example, I went itno reduced engone power last saturday when my intake popped. The car, at this moment went into reduced engine power....and since I had a major vacum leak, I was at around 2k rpm. Was still able to get into 6th gear, and do 80mph.
It's no big deal for me cause I can re-flash the pcm when i'm out,...and it usually goes away.
I did go to reduced engine power when I put on my intake....and went through the gears. I didn't over rev it... it just went to reduced power. Reflashed it, didn't have a problem due to that again.

Ive heard that some beetles do the 1/4 faster than they get up to 60. Thats like 20 something seconds. LS1 Tech Stories
