is there a reliable tune cause ive seen storys about people blowing engines or voiding warrenty. I want the extra power, gas mileage, but also some reliablity any input is helpful

 

trifecta used to have an infiniboost tune where people were blowing engines at 28-30 psi. i dont know if there are any reliable tuners around louisiana so i would go trifecta. just dont go over 24 psi and it will be safe

 

depends on how hardcore u go, the good tuners around are Terminator 2, BYT, Trifecta(most conservative), and Drewbroo

 

The good tuners Lmao. .. Iu want warranty stick with gmstg1

There is more tunes out there op..... Some people crack me up.......

 

im from louisiana too. they have 2 trifecta dealers in new orleans

 

where about? i'm from metairie also. Just looking to get my trifecta updated.

 

TriFecta

$350 for a data logging tune, which is done around you modifications

or

$200 Tune, which is extremely safe and works with basic mods...

I just bought a 2009 SS Sedan, and have ordered a 23psi $200 tune, since all I have is K&N drop-in, Injen IC pipes, and muffler delete. This tune is hidden and switchable,,, unless the dealership puts your car on the computer and specifically looks for it, they will never know its on the car.

 

Here's my story;

I wanted the same thing, reliability and performance. GMS1 sensor issues gave me the scare, so I choose ZZP canned tune and here's why. I choose them because you get a separate ECU and this separate ECU can be switched for warranty work. So I figured if something when sour, I'll just switch out ECUs and get it fixed. Went with ZZP for a good 6 months (if my memory serves me well), no issues.

Then I raced a STI from a roll and couldn't keep up and the reason for that is ZZP is very conservative and lowers the power at higher RPMs for safety. So I was very close to stock performance at higher RPMs. I wanted more power than that thought so I went trifecta.

So based on my experience, I will always recommend ZZP canned tune as a starting point!

 

There's only about 40,000 threads on this..... The only way you don't mess with the warranty is the GM tune. Everything else, search....

 

^ This.

Basic info like this has been covered hundreds of times and there are sticky's on some things as well. Especially Tunes. I'm all for helping out with opinions and ideas and solving problems; that's what this community is all about. But for gad sakes SEARCH

Like whats been said, GMS1 for warranty, everything else WILL void it if found by a dealer and who you choose to tune you is personal preferance. I could recommend a couple that are on here and I tune myself using HP Tuners.

Heres the LINK: all you need to know about different tunes

 

thanks ill check out the trifeta in new orleans

 

Actually not true..

There is an easy way to get a custom tune AND keep your warranty. Buy a spare ECU and tune that. Keep your stock OEM one as it came from the factory. Then you can easily swap back and forth when going to the dealer. Very simple.

 

This is what I did! Best choice in my opinion

 

So basically what you are saying is that a skilled tech wont figure there was once a tune on the car. Its easy, a car comes in for a blown piston, but the ecm was swapped out.. Whats the first thought of a tech with a tuner car (Is this car tuned or has it) Since this car is a tuner car and its in for a blown engine we will have to carefully look this engine over to see if its somehow been wronfully abused.. They can physically send the engine off and have it looked over. Ive seen it happen multiple times some with gm, ford and ect. So having a spare ecm wont always work.....Not ttrying to get a argument going but im not wanting OP to think getting tuned is technically safe.

OP get gmstg1 and keep it at that, no intake, no mods at all to keep your warranty.

 

...and still watch them tell you it was abuse when it blows.

 

You're both right in a sense. I had forgotten about switching out ECU's to get past the dealer which has and will work. And I too have heard of dealers digging real deep to uncover abnormal abuse but this is pretty unlikely. For a dealer to do that to save from replacing or rebuilding these motors is most likely not worth it for them. If they wanted, they can pin that on you even stock. BUT, there is always that possibility of a dealer doing it. It's all up to the owner of the car and what he is willing to sacrafice.

 

How could they prove its been tune if its a completely different ecm? You can tell if an ecm has been tuned before, but u can't tell if the ecm has been swapped out before.

 

The dealer doesnt car about having to fix it, its whether GM wants to replace it. It doesnt cost the dealer anything to replace a motor, GM refunds them the money after they do the work. So a dealer shouldnt care one way or the other as long as they get their money from GM.

 

basically heat index on a piston, cylinder walls, they will be able to see the spray pattern on the pistons to where it should be burning and ect. They can see the abuse ive sent plenty of engines to engineers that broke them down to look at them.......

 

GM will always have to call there Engineers with engine replacements. If they do not its there ass. Reason i say it like that is if they dont get the permission to even break down the engine to see what it is and something is wrong, alot of those people can lose there job or even get fined. Warranty has to do with Corp, not the dealership. So what i am saying is gm will see the engine and they will always inspect the engines.

 

They can and do inspect the actual parts. They probably have an entire dept for just that. Chrysler does. Given the cost of an engine its going to get more attention than some $100 part.

 

Yep, i know when i worked for toyota as a diag tech, i sent engines to our engineers and they looked and inspected them...

 

I know exactly what goes on with a blown motor. Mine blew up last year and they talked to me about everything they had to go through to figure out if they could replace it. And I was tuned with full bolt ons, and they couldnt figure anything out. All they asked me was if I raced it, and obviously I said Hell ya lol All they could fined on my car was a broken oil ring in #3 and scoared cams.

They told me it was bad from the factory cuz it only had 7k miles on it, and I didnt even have it tuned for very long. So how that happened I still cant figure out. It only pushed 18 psi and 2* more timing.

 

Im not tryin to argue here, Im just saying this is what happened to me.

 

I gotcha, and this is because it wasnt sent off. I am talking about a engine that would say blow a piston itself, the ring could have been caused by it not being settle. (You were just one of the lucky ones btw)
