I have a guy who will dyno tune it. but i hadnt decided if i wanna do exhaust/downpipe yet. i was more curious about performance chips or what else could add some serious HP. i would like it to be around 300HP. Im cool with that.
Outside of the fact that I will be buying a stage II upgrade from GM, Exhaust, and intake. What else is recommended in order to increase HP without spending a fortune? I read a lot about different performance chips but I am not risking my motor on a maybe. Any suggestions?
