Default WOT afrs help!

so I when I got tuned, I had 1 cat left on my car... and my WOT afrs were good,..

iand just 2 days ago I put on a straight pipe. and I was wondering if that by removing my cat it would possibly mess with my AFRs ?? and possibly mean that id have to get re tuned?

most likely won't make a drastic change. only difference may be faster spooling and perhaps idle may be just a smidge off. I'm thinking of doing the same thing.

alright sweet,

actually now that my cat is off my car now idles at 14.7-15.3

also when I still had my cat on when I hit WOT my afrs would pin at 10 and now they are between 11.3 - 12.0

my car has only stalled once since I got rid of my cat. , so by deleting my cat it has pretty much cured my warm start up stall problem and also has solved my bad idle hunting problem.

Are you hitting more boost as a result of the new exhaust? Sounds like it.
