Ya the ONE camera idea is going to be the only way to really be able to tell on a medium platform the deepness of the tone and/or raspiness. <- if that's a word lol.
Headers and/or maggie are going to change up the sound quite a bit. So hopefully some guys show up with a little of each. Wish I was out in Cali to meet with you guys!

I am doing some work with Ernie so I can probably borrow it (db meter).
As for the 5th, I don't know if I will be able to bring the V as this work is just eating up any time that I would rather spend on the car.
However, it pays for the mods.
Furthermore, I have a bunch of stuff going on with modding my townhouse that is really eating up time and money.
You guys may have to come south for a change.

Headers certainly woke up the V.
Back in '04, when the V had maybe 15,000 miles, I got a baseline on a DynoJet of:
335.75 max hp / 321.77 max tq
Just took it to the same dyno last week with CAI, B&B headers w/ gutted cats, B&B exhaust w/ X-pipe and StealthV tune and got:
376.65 max hp / 365.02 max tq
Even before correcting, the temps, barometric pressures, humidity were all virtually identical. Obviously, you can't depend on everything lining up equally, but for a gauge, it's pretty good, I'd say...

Good to see you back Jim.

People should expect +30 to +40HP with headers and a good tune!
Go get ya some B&B Headers!!!

So I talked to the local LSX performance shop gurus and asked them for pricing for a tune after my header install. They said 300. Everyone with a LS engine around here praises these guys, but as I looked around their tiny shop i realized they didn't have a dyno, so I asked them how they did their tunes. They do a road tune with EFI. I asked them about getting my tune using a dyno and they said that would be extra. I heard of doing a tune this way if you are just doing small things, but not for something like a tune after header install. What are your thoughts on this? I am under the feeling that I dyno tune is the best form, but I could be wrong.

I'm thinking about going to someone who does a road tune. I kinda liked the idea of them adjusting my tune under real world conditions.
Hope some of the smart people get into this, cuz I dunno what I'm talking about.

What about a program like EFI Live (or likewise) where you can manipulate tables in 200rpm incriments of all throttle positions? You could probably use it on street or dyno...right/wrong??
When you dyno you don't just jam on the pedal and go, you ease it up close to redline. Then look at the timing, A/F ratios and tune accordingly. I wonder if that's how they tune it w/ a road tune?

That's how I will be doing mine. Already have a laptop setup with EFI Live. As soon as I get a free weekend I will be playing around with it before the Maggie gets installed.

Thanks for the info guys. I didn't think the folks around here would lead me astray with this shop. Now I just need to get my motor mounts and diff replaced so I can put these kook bad boys on work on grenading the new one. I can't wait to join the header elite.
