Does the superchip void the warranty ?

jazejeff

any factory service that you need you actually remove the sc program it takes about 5 min. ,once out the dealer can't detect any modification.

OK -- then does the MPG decrease with the SC??

I honestly cant give a good opinion of what it does to MPG. I programmed my superchips at the exact time I put 24's on. However, i have had 3 flashpaqs now and I never saw a noticable increase, or decrease in MPG. Driving conditions vary to much to get a good idea I think.

Shark, yours is stock maybe you can give some info on your MPG after adding the superchips.

Don't be fooledinto believing that "once out the dealer can't detect any modification".

The ECM stores a lot of information and if they are suspicious or get snoopy it can be found out, however it is rare that a warranty denial will result.

My dealership's service manageractually recommended I purchase a Superchips when he realized that GM didnt have a 24" wheel/tireupdate.

I installed the Superchip on my '07 Tahoe w/ 2500 miles. After the next 2500 with chip in, I was getting .9 mpg better. Oh, and I use
Super Unleaded (92 octane).

Well I just went with the base program so far but haven't done any hwy miles yet. Didn't see any change in town. Of course it was done during our coldest part of the winter so hard to draw a comparison. When I get the new cat back on, I plan to do some testing since the Superchips has data acq now. Also have a GtechPro that I haven't used yet. Something about finishing the master bath remodel. []

PS: Is the Beemer in lieu of a rock?

ZX- I recently took my Tahoe in to service to only fix some cosmetic issues. While my tahoe waswith the service dept theyupdated/changed myTahoe's computer.....thus I am nowunable to remove the performance adjustmentsthat were made from SC because it no longer recognizes my Tahoe.Is it possible to have the service department reprogram the Tahoe's computer back to original stock settings? Thanks

Are you saying your stock programming is still loaded into the programmer? If so, then yes you have a useless programmer unless you can get sc to reflash it.
