Power chips

just wondering if they are worth buying for a 2008 Yukon and do they work and if so, what do you recommend??? Not too mechanically savy, are they easy to install and do the affect the GM warranty??? Thanks...Brampton Mike

Blackbear tune is what you need, if they find out the truck has been tuned they will void warranty on spot, but there are ways to get around this.

Yeah a BB tune is the way to go, but GM will not void your warrantty just because of a Bb tune, maybe a programmer/chip could make them do that but def. not just a tune as almost every car needs to be re-tuned after a certain amount of miles or whenever the driver feels its not responding well.
