Sorry but I disagree. I've built race cars, raced race cars, and built cars just to the limits of being street legal. It is possible to make it worse but if you know what your doing and do your research on what parts go with others the best then you can always make something better. But sure if you just through any old exhaust and intake on there you it's not gonna be as good as factory.

 

Sorry, i should have clarified, my ctsv was an 05, naturally aspirated in stock form at 400hp. I did a lot of work to get 200 more hp

 

Not true at all, it is very easy to get 100+ hp out of the new CTS-V. There are numerous shops with 700+hp options that are really only a pulley, exhaust and tune away. If anything I would say the CTS-V is slightly de-tuned as it has a similar setup to the ZR-1 which has almost 100hp more.

 

^^ pretty much exactly what i said in the first place.....

 

You can add hp almost indefinitely (heck, you can create a CTSV top fueler if you really wanted to). But manufacturers (even of very high performance cars) don't beyond a certain point because they want to create not only a balanced car, but also one they can warrant. You can do lots of things to void your warranty, but you will likely then need your warranty when you don't have it after you blow something that couldn't handle the stress.

It's like inflating a balloon. If you have a balloon that's half full (some run of the mill car), you have lots of room to keep blowing it up. If you have a balloon that's near it's limit (a CTSV, E63, etc.) you can keep blowing and make the balloon larger, but the risk of it popping goes up exponentially. The concept behind any production road car is that you can drive it every day and not have to think about winding up on the side of the road. If you're only interested in a track machine (like the potential top fueler I mentioned) then sure, the sky's the limit, and you won't mind replacing parts after every session.

 

Can we get this thread back on track. I'm not interested in the CTS-V, I want to know if a single press of the throttle is really changing anything. This to me sounds like the same snake oil that says if you old your keyfob up to your chin then remote start will have greater range.

Can anyone point to something in the factory service manual that says a press of the throttle as described by the OP resets anything or engages some sort of enhanced throttle settings???

 

can't point to anything but the old remote on the chin thing does work! FWIW I did the gas pedal thing and I thought it worked.

 

I thought it worked too but i can't be absolutely sure since i don't have a dyno....

 

Strange, that sounds a lot like the reset procedure for the DIC oil change warning. (Three times for that) Must reset something or other.

There seem to be quite a few "easter eggs" in this cars internals :-)

BTW the remote start with the key fob against your head does, to my great surprise work, for door unlocking but not for remote start... duh. must have a metal bit in my head somewhere....

 

yes it does work especially when you go to a bigger throttle body assembly
