There are no plug and play options. If you live in California, don't bother with other options unless you have a personal smog guy. As mentioned above HP Tuners (HPT) is what people use. It requires a great deal of knowledge about air fuel ratios, engine timing, and too many other details to mention. For this reason most people go to either a local or a mail order tuner. For mail order you need a product that can log your cars performance to send back to the tuner to get it dialed in. Trying any other option you risk blowing your engine. No cheap way to improve performance. You bought a high performance vehicle so Bite the Bullet and spend some money if you want to go faster. You might want to invest in a driving school first so you don't end up like a Mustang at a car show.

Tough crowd here, but settle in and read for a while. There is so much knowledge on this board that you can soak up. Be patient and look around. You will learn tons here.

Yes, that is the intent.....sadly, the road to knowledge and all of the hp's is littered with broken dreams and conn rods.

"Evans Performance Academy" offers a very good GM Gen4 Master course that can help you get started to learn HPTuner, go to Youtube and check out some of the promotional videos. Kyle at "Goat Rope" Youtube is a good source for learning as well. HPTuner is a real effort to learn, countless hours, at least for me, but well worth the effort and investment in the long run!

1. Unlike facebook groups and most other 'badge' forums, this place is where folks who are serious about CTS-V modding and performance gather.
2. This can be a tough crowd for folks who buy into internet gadget pitches and whizz-bang widget believers who expect to improve their car with a glitzy LED-festooned plug-in magic bean
3. Despite the sometimes harsh response to mentions of snake oil, if you grow a little thicker skin...and ask how to improve the car to unleash its real potential, you will find a wealth of info here.
4. Inquiring in a racer's forum about chip tuners is like suggesting perpetual motion machines at the patent office. It's going to go downhill rapidly.
5. Donning an attitude and instructing the forum how to address you is a fool's errand, but let's get past that.
6. Let's start over. Tell us what you'd like to get out of the car, what your plans are for daily driving or track use or...?

I'd just drive the car as-is for a while. It doesn't really have enough tire for a meaningful increase in HP, so if you want to squeeze more out of the engine, you should start with aftermarket rims and wider hunks of rubber... Then, the easiest way to get more power is to pulley the blower for more boost. But the ECM needs to be reprogrammed for that, and that's where we get in to the software-for-tuning discussion. HPTuners is the most-universally accepted solution for that. But as stated, using that software correctly requires a decent amount of knowledge and you're likely to break something if you don't have that knowledge and start poking around. So your best option is probably to find a remote tuner (this forum can help you with that), discuss what mods they can handle, and go from there.

"Chips" as you have discovered, are looked on with disdain. There's very little you can do from outside the ECM that results in more power. The "chip" has to spoof sensors values to trick the ECM in to making more power. But the ECM is designed to maintain emissions compliance even when sensors start to fail. So if you chip the engine, it might perform better for a short while until the ECM adjusts for the new conditions after which performance will return to normal. Chipping is a waste of time and money.
