Headers and O2 sensor tuning? Have a set of Pacesetter headers. Don't have time to get the thing dyno tuned yet, but I do have efi live and I can turn of the MIL's associated with the 02 sensors that will show up with a lack of cats. Will this be alright as a short term fix or will this cause problems? I should know this, but being a diesel racer we dont have o2 sensors to deal with and dpf's, and egr's can simply be turned of.....

I had my pacesetters turned off with hp tuners. Haven't had problems since. You reuse your front O2s and leave the rears off since there are no bungs for them. Just turn off the rear O2s and you should be good...

Appreciate the input folks. I use EFI live so I can go through and punch out trouble codes by code number, if anyone has the correct "p****" codes it would be awesome. Thanks

Or if you want just plug it in start it and scan for the codes.
