CAT Cut out?
For a while i've been thinking about cutting the converters out from under my truck but i'm a little worried about what will happen, i know the check engine light will come on b/c it has two converters, and each has an O2 sensor behind them. I remember unplugging my mas airflow sensor the power sucked on the bottom end. would the same thing happen if i cut the cat's out from under the thing and the computer throw a very weird fuel and timing curve to compensate for it, or would the check engine light just come on? Little advise please. THANKS!!!

if it gets tuned with "ls1 edit" it will help with will help the mileage and will do away with all the closed loop/open loop bs.
my cousins 5.3 truck has true dual with no cats, CAI, TB spacer, built trans ,LS1 edit then it was dyno tuned. it gets 22-23mpg on the hwy on a 235,xxx mile motor.

any good performance shop that messes with camaros and corvettes will have the ls1 edit program.
they may also use another program besides ls1 edit, that does the some stuff.
when he did the edit they deleted all his egr and emissions stuff.
its crazy your stock trans is held up for over 250k
