Mike...if I install some LT headers...and catless mids...

[Chi06SRGTO]

Would you guys be able to send me a tune, tuned for the headers, and to delete the rear o2 sensors? PM me if you like. 2006 GTO

The rear O2s are already deleted, but, yes.

Thanks

Really? I didn't realize that. So the canned predator tune on the U7191 deletes the rear O2 sensors? So if I installed headers and catless mids, I wouldn't throw the code for the rear O2 sensors? That's pretty cool.

I used the canned Predator tune when I added headers and catless mids. No codes at all.

I put the car on the dyno and only got about four more whp out of it working the A/F. The Predator tune works well with the headers/catless mids.

I figured it would. I'm thinking adjusting the injector slope and PE fueling after installing the headers, would yield good results. I'm sure a custom tune from these guys would wake the car up even more. Really debating whether or not to order the LTs and catless mids... $500 isn't bad.
