I heard the answer is "no". I plan on this throttle body, ported snout with 2.5 pulley, air intake, tune. That should be enough...lol!

You may need tuning for this mod to realize gains. I installed one on our ZL1 and was surprised to lose 12 RWHP. After tuning, it gained it all back and then some.
On most CTS-V's we gain 12-17 RWHP just from bolting the LS3/LS7 TB on but there is no predetermined result on how the air model will affect the calibration. It won't hurt anything but you may have a bit of a power loss until you tune. |

Question: Did you guys bolt the 90mm TB onto an automatic or manual (stock) ZL1? |

This is why just about all the tuners came out and stated not to make intake changes without a tune because of what they found with the MAP tuning (scalar values an offset) on the ZL1. GM made changes that were necessary for this car to meet emissions that weren't necessary for the CTS-V's. They also did it to purposely protect themselves on fraudulent warranty claims. If you just swap intakes or TB's the car will run lean with the factory values because the pressure reading will be off and the ECM swaps to a different fuel table as a protection mode. So yes there is power to be had with changing intakes and TB's but it will require changes to the MAP tables to safely and effectively do it. Yes...void the warranty. GM learned their lesson on the ZR1 and CTS-V's.

Well it wasn't those cars specifically as much as it was any car being modded. But when it came to their cars with the high dollar engines/transmissions they realized they had to something to protect themselves from fraud and abuse. I'm sure you know GM has folks watching these forums and they are very well aware of what's being done to the cars and the mods that are made. Believe it or not GM does know that people want to mod their cars and that have that in mind when they are designing some of the powertrain aspects. They make information available to the aftermarket companies so they can build their products. The problem has become abuse of manufacturers warranty and letting them foot the bill for repairs that should have been the owners expense. Making heavy mods that blow up an engine and then removing all the aftermarket parts and tuning to make it look like the car was still stock is abuse of warranty. GM learned their lesson so this is why the ECM's are now set-up to log a change in factory tuning. If you blow up a $20K LS9 because you modded your car it shouldn't be GM's responsibility to pay for the engine replacement. After paying fraudulent warranty claims on Duramax's, Camaro's, CTS-V's and ZR1's they decided to do something about it. All these vehicles have high dollar engine/transmission combo's so of course they are the target of the new software that logs changes.

That makes sense. Too bad theres not an acceptable level of mods or a list of approved tuners who could make "reasonable" changes that wouldn't adversely affect durability. I know this isnt likely to happen, but it would be nice.

I don't blame GM one bit for all the precautions they take. Having said that, I wonder if the pcm keeps a log of the odometer, surely it does. Someone could just purchase a replacement pcm, then tune on that one. So if something does happen, all they have to do is put the stock pcm back in to make a claim. |

Manual. I noticed an improvement in power and sound on acceleration. No tune yet.

BTW.. don't be so quick to jump on the bandwagon of feeling warm and fuzzy about gm getting out of warranties. Its not always fair, and they will try to void any warranty they can as it saves millions in financial obligations. Its business, not a fairness issue.
Fact is, If you tune and then your oil pan leaks you will be denied warranty on the oil pan leak based on the tune, which is not right either.
