i noticed it seemed to eat alot more gas than usual. lol sounds stupid, but just checkin

 

retune, also not sure if your catless you need to fool the 2nd 02

 

I'm not really an expert, but I think don't it has anything to do with gas, but don't take my word for it. You never know.

 

im runnin the stock cat. tp not installed yet.

 

Get yourself an 02 spacer/non fouler and check your tune.Also make sure your not going a little heavier on that pedal on the right without noticing .

 

i do have an o2 spacer. i dont have the tp on. im running the stock cat, because i dont wanna be so loud. haha i shift no more than 3k dd. barely noticed the gas consumption yesterday. i took off the blox filter and running the stock box now. havent gone out to try yet. will do so tomorrow. let's hope to see some slight changes in gas consumption. haha

 

without a tune, youll be running slightly richer, which means more gas usage...

also check the right foot

 

which is better for now, without tune yet; tbe or just the catback? haha i dont drive that "heavy-footed" lol
