I have done a search couldn't find what I was looking for, so the question is what is a tune worth on a stock Z06.

3 Z06ZR1

If you are doing some mods and need the tune . Ok but the tuning could mess with the warranty on the engine. If have other issues like say with the seat or something it wouldn't affect that.

That said if your not tuning for mods it may not be worth it. Not sure if you would gain anything if so it would be little. Not many tune the stock car.

"BoneStock"

From what i have seen with no mods its about 30-40hp.

3 Z06ZR1

I really doubt those numbers! So GM left 30-40 safe hp on the table ?

I dont. Thats ~5% gain on a boosted car that runs super rich from the factory. Leaner is not safer, but "safe" is a relative word.

3 Z06ZR1

You should!

I did tuned and headers a while ago and My dealer doesn't care. As long as your not bringing it in with major damage. They have handled all concerns under warranty with no questions. The mods really make the car.
The stock Z06 M7 is no where near the car as the car with mods. The aftermarket is so strong. My z06 is much better in all respects over the stock unit. MGW shifter, 140 hp, and the DSC shock controller etc .even powerstop brake pads along with tuned exhaust. All add major changes in feel and fun and enjoyment to the car!
But just a tune no!

Speed inc, Bone stock, then stock with Tune. AFR pegged rich on stock, about 12.5 tuned.

+43hp, tune only

Some notes on the first link, I have had my Corvette's on 3-4 different dynos' different cars about 14 times. Watching my tuner each time. My tuner does maybe 3 full pulls but never 29 pulls after the first pull. The second has no AFR. My tuner sets them to 12.2
The bone stock cars I see don't make those numbers. They are the ones selling the tunes! They may add octane boost and other tricks to bring them up. My boosted stingray had 618rwhp left a vendor where the same build where most only made 570 and it never was a good car or fast after that. Things may not be as they appear.

it could be worth $20000 if you have a engine problem and your warranty is still in affect.

It is not the dealer. GM has the last word and you will not be happy with their decision.

GM knows nothing beyond the dealer. Tunes are fine till you bring your car for major engine work. Just normal warranty work the dealer is fine and doesn't check if it is tuned. Depends on what the issue is. As to what they do!

lordofwar

I do not know 1 way or the other,but what I do know for a fact is everything you are told by other people is only their opinion.real life experience is the only thing that counts.and I would not want to bet the 20k motor on that.

What warranty work have you had done, since you made your mods?

3 Z06ZR1

Was just there because my bumper to bumper 36 months is up.
Almost 10 years with them.
Had them check why I get a reduced power once in a while. They did the service work and the check under warranty now I know why it was giving me reduced power.
First thing they noticed was the blower swap. They liked it!

They know I had the headers, intake and tune and don't say a word but I'm not there for major repairs. Just did the 30k service, tranny and rear end drain and fill. I have brought them donuts in the past and the parts manager and I have went drinking before. Plus they took courtesy delivery of my car from a forum dealer order for $300.00. They went to bat and got me a repaint at my choice of shop as well. I feel at home there. We are friends. Even the owner likes me!
Had them look at my starter button and they also replaced my PVC
after I JB welded it closed they didn't say boo!

So you doubt a tune that leans the car out would make 30-40 horse but your air intake that leans the car out can makes how much??

My thoughts are considering the upgrade costs to the ZR1 and the extra 105 hp. Easy decision for me. I'm willing to mod and spent some and upgrade the current car. The chance of me needing a engine replacement which GM could balk at even under warranty if the engine lets go at 6,000 RPM
at the track. Are very slim. The aftermarket is very strong with so many quality choices. Even just superchargers there are 5 different ones.
real life experience since this is kit number 4 self installing the 3 of 4

if your warranty is up and you want more power,that is a personal choice.if it is not up and motor goes,that is a gamble you are willing to take, that is a choice also.the op has a stock car and a tune should probally not be his first mod.i agree with you on aftermarket power options.you can make 1000hp a lot cheaper and just as reliable as a 2019 ZR1 upgrade.
