Emissions and Noise-First Cat. Removal ?

[ddmcse]

when you go from stock to modified at some point you'll start hitting Fuel Cut Off FCO. we're talking turbo supra.
once you let the car start to breathe the computer will realize that there is way more air flowing than normal and you'll throw a error "code 34"and at the same time you will shit your pants
because the EFI will cut off fuel for just a fraction of a second . now picture this ...

you are punching it hard and the car feels real nice and it's pulling good , you're smiling big .. then all the sudden WHAM ! it's like you hit a car but there's none in sight
if you're not expecting it you will shit your pants .

you will quickly learn either
A:
not to punch it so much

or

B:
figure out you need to spend more money to get rid of that shit
