Ready to race!
Hi guys,
I'm a noob. but i installed a catless downpipe on my 2010 gti dsg and now have a CEL. i've been reading that spacers between the o2 sensor and the downpipe will "trick" the car into thinkin there is a cat there and the CEL will go away... is this true?
i am also wondering if me going stage 2 now is REQUIRED due to new downpipe...? (50-50 of ppl saying yes and no on other forums for other cars)
i read online that cars will run lean if they aren't stage 2 tuned...true/false?
or will the car run lean because the o2 sensor sees that there is no cat converter anymore so the ecu will change the AFR itself?
and im guessing running lean will screw up major components, but how long would it take to do so (incase i wanted to stay stock for $$$ reasons now) ?
some of my friends say that the CEL is just indicating that the cat isnt there anymore so no worries (i already know that cuz i installed the dp) its just a light on the dash and thats all, but is the CEL relaying the msg to ECU and having it run leaner???
IF ANYBODY CAN ANSWER SOME OF THESE QUESTIONS I'D APPRECIATE IT.
sorry i'm so "ignant" bout this stuff. i've never modded a car b4
