Hey Mikel......I am puttin headers on my 04 GTO this Friday.....Can u do a header tune up for me? Montess did a cat delete tune for me that I am using. My mods are just CAI, and catless headers.............ProProducts 85mm intake to come..........

Here it is modified for your setup.

Thanks! Can I ask what kinda changes you did? Just curious!

Well i based your a/f on a 04 gto that i did here on the dyno.
I also changed your low end timing as it was stock and i fixed up your trans settings, alot of it was stock.

You rock!

Lemme know how she feels..

Hey Mike... Im a memebr over at ls1gto and I was told to come here for a header tune. Im going to be installing my headers this weekend and wondering if you can do a header tune for me. Its an 05 gto and my mods will be long tubes with cattless mids, CAI and a custom cat back. I am currently running the 91 octane tune from the predator hand held.
Thanks

need to post up a copy of the diablo tune that is currently in your car...

This is what i have on the car rigth now the only difference is that i will be deleting my rear o2's once the headers go in.

here ya go man.... O2 codes disabled...

hey darkstar, just re-read your post...

you're doing headers and REMOVING the CAT's??

well, with no cat's you don't need the COT strategy on and runnin, so here's a tune with that disabled as well...

Thanks man
I will be trying this out once I get them installed.

Well i got them installed this past weekend and added the tune, after a day of driving i got a engine code today...
