Got it tuned at Domin8 Tuning. It's a very conservative tune as I wasn't going for numbers; rather, I want reliability and driveability from its 113k miles (and climbing). So, while it made more power than we ended up with, I'm happier with it this way. It's obviously being choked off using the stock midpipe and axleback, but those are retained for the sake of flying under the radar. I'll post a video later when I'm able to get it off my phone.

345hp 376tq which is around 400hp/440tq at the crank.




Winter mode!

Already have the 18's back on the rear. I probably won't swap my winter tires until Easter.

We've got some aftermarket 17s with snows for the winter. they came with the car, so basically free. lots of sidewall for potholes protection!

I really need to update this... I did a DOD delete with a LS3 cam this past spring and I'm now making 390/385 still through stock exhaust. Haven't made it to the track yet, though...

This has been my DD. Against my better judgement, I bought my wife a new Acadia about a year ago. I'm done modifying this one, though. Not sure what direction I'm going to take as for getting another car, but I am ready to move on to something more "fun." This means I'll likely buy another f-body, lol

It's really been great for a mixed city/highway DD. I'm getting about 18mpg mixed (~300 miles to a tank). It's not Prius efficient, but it's sure a hell of a lot more enjoyable to drive.

Granted, it's not the fastest thing out there, but it is a good all-around worker for daily 60 mile commutes. I'd honestly not change a thing about this "build." I do miss having a stick, so in hindsight I wish I would have bought a 1st gen CTSV. Otherwise, I'm not second guessing anything.

If anyone has interest in reading about the DOD delete I did -- I spent $600 in total and gained 40rwhp -- check out my thread on the process here: http://www.g8board.com/forums/5-v8-e...questions.html

No, that's with a take-out LS3 cam from a Camaro (I think I paid like $50). That was the only change I made between dyno runs. It's the most affordable way to do an AFM delete, IMO.
