2005 GTO LT Headers and no CAT tune?
2005 GTO LT Headers and no CAT tune?
1. U7191
2. 9r02
3. 2005 Pontiac GTO
Can any of you guys help me with a LT Headers and catlless tune? I have searched everywhere and figured out its something somebody else has to do for me. Who do i need to call or talk to? Also the car has a Texas Racing 224(224/224 .566/ .566 114 LSA) cam in it and all i did was raise the park and drive idles. I figure once the Headers and pipes go in i was going to log it and see what you guys thought i should do from there. Thanks guys for the help!!!

these are the only tunes i have for the car. The backup tune is exactly that. The GTO tune is the one currently in the car it is a modified Diablo tune. Let me know if there's anything else you need. Thanks again Mike!!!

np man, you're welcome...
but - I didn't touch your idle.. heh...
it's idling a little higher right now because you reflashed the car... so the idle and ltft's and all that need to be relearned by your ECM... once the tune settles in, your idle should fall back down to where it was.... but you can go in and "Modify Tune" and bump up the idle yourself to fix that...
