There is a very long thread on the Z06 board about lean codes with the Stinger. It might only be a Z06 issue, not sure, but multiple Z06 owners get lean codes from the Stinger.

I sent you an e-mail as well, but for the benefit of others:
The way I understand it is that after your intake air temperatures reaches 110 or so, the CPU starts to back off the timing, reducing power. At 135 degrees F, your engine is down approximately 10 HP and this is noticable. Have you ever noticed that early in the morning, your car seems faster than during a run in the afternoon? This is precisely why cold air intake systems have an advantage over non-cold air systems. My cold air mod was conceived after my reviewing quite a few methods. I even designed and built my own custom intake scoop. However, when a forum member suggested that I try an $8.00 wall pocket (Staples, Office depot, etc), I decided that it would much easier for anyone else to copy my method if the coponents were easy to obtain. This is why I used an unbreakable wall pocket behind the lower radiator cover.
My 15-page (very detailed) procedure for doing this mod is available for download in Halltech's website. You'll see a link to it on the main web page.
Canesfins,
Most Z06s do not have an MAF screen. It is possible that the combination of more air flow and no laminar flow into the MAF wire elements are causing the lean codes. My guess is that tuning would correct this issue.

Right, but a $500 tune to correct a problem with a $200 intake doesn't make too much sense in the pocket. When a fix or alternative comes about I will be in the market for a Stinger, unti lthen, I think I will stay bone stock unless the new Vararam gets tremendous reviews or is a little more "profesisonally built".

Dave,
Thanks for the response. I did find your tutorial on your cold air mod on the Halltech site. Not being very handy, Not sure I want to tackle it. I may have to put the stock bridge and coupler with the warhead on the car. For some reason, I didn't get any codes with that setup. Perhaps I just didn't have it on long enough. One way to find out.

Still, I will investigate the Z06 code allegations: there may be something else going on of which I am not aware.

I have the one from West Coast Corvettes and it has a C5 Logo on it. While the hood closes properly and does not distort, you CAN see the imprint of the logo on the hood liner so I know that it is very close 
I am useing the Donaldson Blackwing based on the fact that I did not want to drill holes in the car but I DID want the extra kick it delivers 
A lot of the aftermarkert breathers require some drilling and I did not trust myself with a power tool that close to the radiator 
Good luck and keep us updated

Sometimes the rubber coupler need to be trimmed too.

However, let's say I tune my car with LS1-edit and my headlight mechanism fails; the dealer MUST repair the mechanism at no cost (if still under warranty) because the tune has nothing to do with the mechanism.

Since I do not know exactly what an LS tune does, what would it effect that would run a risk to the engine (parts failing)?
NCC-1701, how long have you had the Stinger on your car?
Dave, If I purchase a Stinger and get lean codes on my Z, will Halltech take it back no questions asked?

If you happened to lean the mixture too much, permanent engine damage may occur. Running far too rich would at least cause your cat. converters to fail prematurely.
BTW, I have e-mailed Halltech regarding the lean code issue and report back when I hear from them. Normally, there is a 15% restocking fee, but if you do order, you may want to discuss their waiving the fee if a design problem is the cause for code generation. Personally, I have a hard time believing that this has anything to do with the design.

I appreciate it because I sincerely believe that the Stinger is the best bang for the buck right now, as long as it works properly in my Z and I am not at risk to damage to the engine, and not having to reset my codes all the time. I know you are close with Halltech, so I appreciate your efforts and advice.

Stinger-R = great bang for your mod bucks! BTW- No codes here, but then again, I've got a 2004 Coupe!
