Not much if any. It would be barely noticable if that.
For around $180 you would receive a piggyback adapter that fits between your stock chip and the ECM. It is always removable so you can go back to stock settings. You can change fan settings, ect.

That would depend on were the tune is currently, and what your goal is with a custom tune (performance , fan settings, vats etc.). What I have seen is that a GM tune is ball-park at best. However if you were to go that route, to achieve the best results would require you to be able to send data-logs to whom ever you choose as a tuner. This would then necessitate the use of a laptop, some software and patience. JMO

There is some benefit to a good custom chip even on a basically stock car such as yours. Just dont be looking for 50hp out of the chip. BTW, I have used 3 tuners in the past. 1 was a total rip off. 1 was decent and 1, pcmforless was outstanding. If you would like to know who I consider a total rip off and why, PM me and I will explain.
