Yeah, who has the software to do it now? We are still waiting for Efi Live to be released for the LS7.
Make sure they get before and after figures.
Before you spend a fortune on a custom CAI, the US Corvette forums are getting very excited about the power claims for the new K&N intake. They claim 27 rear wheel hp and it only costs $350!
Nobody has reproduced that yet, but it does seem to work better than most.

It's discussed heavily here: http://forums.corvetteforum.com/showt
There is a link to K&N in the first post and there are vendors mentioned within the thread.
I'm probably going to stick with the Lingenfelter CAI unless someone proves there is a dramatic difference.

Hmm. Seems a little high then! The engines are all tested to be pretty much spot on 505bhp at the flywheel so 480rwhp would seem to indicate an unfeasibly low 5% transmission loss...
However rolling roads are only really ever useful for comparing mods, so it will be interesting to see what the CAI and tune add.
FYI, on vixpy1's Dyno Dynamics RR, my car measured 409rwhp stock which calculated out at 499bhp. Ericthevetking's was almost exactly the same.
Everyone seems to agree that Dyno Dynamics RRs read lower than Dynojets, but still that's some difference!

I agree with the differing Dyno results from make to make. It still surprises me though, as you`d think they`d be fairly similar. It`s like weighing 1 kg on one set of scales and it equalling 1.5 kg`s on another!
However, my cars at the top of the power tree, compared with the US Dynojet numbers.
We`ll how it turns out.
The dyno guys are impressed with the whole car so far....
Just a fyi for anyone wondering. efilive has announced E38 PCM support
http://forum.efilive.com/showpost.php
Initial release due 22nd March.
So you DIY guys can get all the info you want from the stock ECM.

Too be honest, its about what i'd expect on a Dynojet
Tuning results Monday. Don`t think there`s a massive gain, but worth while.....
Regards the quoted power outputs from the Dynojet:
My experience of the twin roller type dyno`s have alway`s been less than good. The car`s and trucks have always climbed out, wheel spun, burn`t rubber and shut the dyno`s down because of over speeding the dyno. It`s also an unnatural twin contact patch on the tyre`s, creating double the drag. The dyno shop`s (in my experience) could never put the required load on the car.
Now with the single roller Dynojet:
Park it, strap it, put as much load on as you want(in forth gear) and clean pulls every time.
My local tuning shop have just had a 1000hp drag Supra in. Dyno`d underload, no problems.
This is MY personal experience of VARIOUS dyno tuning.
Anyway, the sound of the Z06 on the Dyno is worth it, what ever happens!
