747Racing Posted January 18, 2007 Report Share Posted January 18, 2007 Alrite, so I'm thinking my tranny is on the way out. I have a CAI on my truck and a superchips tune. The reason I got the superchips is because I can just pull it off at any time and as far as I know GM is none the wiser. Is that true or does it put a code in your computer? Also, would a CAI void your warranty? Would exhaust void warranty too? What can you do that won't void your protection? Let me know guys, Cheers!

JF-03-SS Posted January 18, 2007 Report Share Posted January 18, 2007 CAI and/or a cat back exhaust should not void your warrenty. A tune will void, but they would have to prove that problem is due to a mod. Quote Link to comment Share on other sites More sharing options...
Stitches040 Posted January 18, 2007 Report Share Posted January 18, 2007 CAI and/or a cat back exhaust should not void your warrenty. A tune will void, but they would have to prove that problem is due to a mod. I asked the Service Manager about a Tune and Warranty when I got it. He was hesitent, but said the Tune should not void the Warranty, as long as it did not make the engine do anything outside of it's normal operating parameters. So, basically ... Don't make the thing redline all the time. Plus I kept my Original PCM. If need be, I can always send the Tune back to PCMforless, and have it re-flashed with the updates for $50.00.

misterp Posted January 18, 2007 Report Share Posted January 18, 2007 (edited) If the dealer can prove within reason that any post-sale modification contributed to a component failure you're SOL; else they have to honor their warranty (it's federal law) i.e. the manufacturer cannot refuse to fix a failed radio because you modified the vehicle by installing non-OEM turn signal bulbs. That said, it's pretty easy to get into a pissing match with a dealer over a change you've made to your truck because reality is that they are *not* very knowledgeable about automotive mechanical systems, so there really are a couple dealers out there that honestly believe something as BS as changing a light bulb *could* possible burn out a radio!

Bad Bowtie Posted January 18, 2007 Report Share Posted January 18, 2007 Yeah, it's really up to the dealer. This topic seams to vary on VERY different levels at all of the dealerships that I've been to.... Quote Link to comment Share on other sites More sharing options...
Fireman31 Posted January 20, 2007 Report Share Posted January 20, 2007 I believe that aftermarket mods are protected under the SEMA act if i'm not mistaken.......... Quote Link to comment Share on other sites More sharing options...
SSAlaska Posted January 21, 2007 Report Share Posted January 21, 2007 How could they even tell if you have a tune? Quote Link to comment Share on other sites More sharing options...
misterp Posted January 21, 2007 Report Share Posted January 21, 2007 (edited) How could they even tell if you have a tune?Dealers do not have the software necessary to reverse-engineer your tune. This is my guess and you Goodwrench guys would have to confirm or deny this, but I guess that the local dealers might be able to dump an image of your PCM to a file and email it to a GM powertrain engineer for further examination. But this has never happened, ever (to my knowledge). In reality tunes go unnoticed, as well as the Trailblazer torque converter, shift kits, ported GM heads, and milder cams. About the only thing you can do to tip-off Mr. Goodwrench that you have a modified LQ9 is install FI, NOS, aftermarket intake/headers, or a cam with a lot more overlap. Mr. P.
