No tune? 370 seems like a stretch to me.

Yeah, no tune.. I'll prolly just use a diablo for that until I can take her to the dyno.. Seems like most are saying between 350-380whp with my mods so we shall see! Regardless, I can't wait to see what my butt dyno says! ahaha

are you getting kooks 1.75"? you should take a whole slew of pictures when you install them, including the clearance with other parts (steering shaft) and ground clearance.

i'm still not sold on putting headers on my car for how i use it and what my plans are, but i'm sure i could be persuaded. i know for sure i don't want the 1.875" versions and i won't put money into buying a knockoff set (OBX).

I made 350 untuned with headers, cats, K&N, and ported intake manifold. The ECU doesn't adjust very much, so the more parts you throw at it without a tune don't really do anything.

If you're having a shop weld in the cats I can't think of any issues.

Not to threadjack, but does anyone have 'back to back' dyno results on these cars before and after aftermarket clutch/flywheel install? Curious of drivetrain loss gains. I know that after my LS9 install it felt faster but not sure if that would register. Maybe a stupid question...

Warranty??? On an 05 Cadillac? How much longer do you have? Mine goes to 125k but I'm going to cancel it and get the rest prorated. This car is going to get gangster before 125k miles I hope.

It would be a pain, but you could always swap them back (get an extra PCM too) if need be for warranty purposes.

Not really, you can save stock tunes and any tune really and revert back. No need for another ECM.

Nice gain!

As for the PCM, I wasn't sure what method he was going for the tune. Currently, I just have a W4M tune, so swapping PCMs would be easy (not that my 120k mile, rebuilt titled car has a warranty to worry about).
