I always get the wise guys for students here. Not only are you a wise guy and smart aleck, but you also have a really nasty habit of misquoting others for your own misguided purposes.
I said "I use them to detect radar, laser et al locations. I am sensitive to the fact that some radar et al equipment has not been calibrated correctly."
Once again,
class dismissed..

One more thing, words like "smart alek" reveal anger which is analogous to "flinching".
In your anger, remember that you are the one stalking me and inserting yourself into posts that are not addressed to you.

Last I heard, this is a public forum and when you make a posting anywhere here, its fair game for everybody. This is why you are so funny with your "stalking and inserting".

I hope Chuck at CoW reads this since he has been claiming, for some time now, that his "special" (whatever) tune won't cancel your warranty. I've called 
on that for some time, but a few still go on and on about federal warranty law, how unfair it all is, etc.
Hey, Chuck - YOU'RE WRONG!
If you modify the powertrain, the powertrain warranty is gone. Period. Why, oh why, is this so hard for people to understand?

also, my dealer techs told me that i was more than welcome to install LT headers, intake and catback with no worriest about warranty denial issues. i got a tune from Chuck CoW on a seperate computer that i can swap in and out.

i beleive the way chuck has been going about saying this, atleast this is how i took it, he acknowledges that claims will be denied, but things like if a window motor stopped working, or a radio stopped working or something, the entire cars warranty is not gone, just certain parts.

unless of course, they're stating that THEY will pick up the cost of the warranty work. minor stuff, maybe. major-major, we will see. keep us posted.

Did you get it in writing? Because you'll need something when GM denies to pay them.

Not saying this will happeen, but I see this as a potential flaw of those separate ecm's, particularly with a fair amount of added bolt-ons. Ie: the more bolt-ons you got, the more they rely on a modified tune. And the more bolt-ons you got, the more chance they give away that you tried to fool somebody by putting back in a stock ecm.

What happens when you put your stock ecm (computer to you) in when you go to your dealer for say a tranny issue. You'll most likely get a CEL light over your headers (though your tuner disabled DTC's on the tuned ecm to prevent those CEL's). Somehow I dont think the Dealer will believe you have been running a CEL for six months since say, your last visit. Not to mention suspicions by the GM rep for pricey warranty work.

it only takes me and my buddy about an hour to swap out the manifolds and stock system for the headers and stuff. not worried. if completely major issue im not going into the place with all that stuff on the car.i dont feel very bad about doing that because headers and intake arent going to cause catostrophic failure. if i was installing a supercharger, nitrous, cam, etc, i would not do anything of the sort.

If the repair bill is over a certain $$ amount,yes it has to be approved by the zone rep......and I promise you he won't care about any arrangements you may have with the local dealership.

A friend of mine worked at GM dealerships for years. GM does have a regional rep that goes around following up on warranty work, looking at replaced parts, etc. The dealerships do fear the GM Zone rep. However, having techs that know you and having a good relationship with them will go a long way in preventing you from having any issues. But there are no guarantees.

Depending upon the extent of the warranty repair, the zone rep may take a look at the car.

I dont know how he would come to the conclusion they were just put on.. theres no computer that says a bolt was unscrewed 3 hours before. The manifolds were on the car for almost 4k miles before i just put the headers on. And really, id love to hear of some way that headers are going to cause catostrophic failure. I wouldnt even bother doing the header back to manifold swap for basic warranty work if need be.

I posted this in Autocross & Roadracing section also.

I work for a Chevy dealership and peruse emerging issues when wor is a bit slow. An interesting issue came up in Jan I thought might be of interest here. As of Jan, we are to look for aftermarket tunes on any vehicle brought in for drivability concerns & warranty work comes into play. Aftermarket NON GM tunes will VOID your powertrain warranty. PERIOD!!!

Does an aftermarket place such as "vette doctors" or any other aftermarket vendor who is authorized to do GM work. If they tune your car does it still void the warranty?
