C7&7

Get you a new tuner dude.

Who was the shop, Plus if this shop are guy looks like it is worth any thing. I would take him to small claims court that is if I could get a GOOD shop are tuner to say it really was the tune on the car.

Too rich can, supposedly, do some pretty bad cylinder washing on DI engines

I'm not sure how that'd cause bearing issues though. That sounds more like knock to me

This is the risk we all taking adding superchargers, etc. It's not common for this to happen, and may or may not be the tuners fault.. but ultimately all you can do is move on and up

Just be sure whoever tunes it really knows what they're doing. I wouldn't use a remote tuner for something like this personally. If you were closer I'd check it out for you but little bit far from NC!

Thanks for all of the feedback and concern, I really appreciate it. For those interested the car was putting down 528 rwhp before it failed. I'm not interested in giving out names as I do not believe that it was ultimately the installation that was the problem. Most likely the tune or a flaw in some manufactured component, but then again I am completely naive with all of this. From what I have read I was under the impression that fueling and component damage wasn't to be expected for anything under 600 rwhp.

It's highly unusual, which is why everyone keeps mentioning the tune

Who tuned it?

robert miller

I can agree on the OP on the blower install but who done the tune on the car. Crap man If me common sense should tell you if it had a good and correct tune on the car I don't see this happen to the motor at all at that level of power. Guys in here with all stock parts with 700 plus rwhp. So I would put money on the tuner on this. Robert

Need to know which one of the local guys done goofed. I'm suspect of all but a few locals when it comes to gen 5 stuff.

Good luck with this OP.

OP mentioned that the car was remotely Tuned.

zrracer

Did you put in larger injectors?

Detoxx03

Remote tunes make no sense especially when you have Futral and Asylum local

RpeterK

That was a thrust bearing issue from what I recall

C7&7

Yea.... too rich or too lean or knock or no knock this issue was tune related. There are just too many supercharged c7s out there and they don't blow up on the dyno.

If you think you are kicking yourself now, wait until you pay someone to do the work again and could have a similar but much more expensive problem.

There are only 2 options:

1. There was a defective part in your engine from the day it was built and the added stress caused it to fail.

2. Installer/Tuner screwed up something.

I've been down this road before unless you get an answer that makes complete sense go somewhere else before spending another dime.

FYREANT

After a major failure like this, and it being 99% likely due to a tune issue, its time to start telling yourself that shipping the car to a WELL known C7 tuner is the right play. No remote tunes when meth and boost are as involved as they should be as they don't see all the logs that a real "hands on" dyno tune provides..

I will are would put money on number 2 in this case.

funny I had the exact same situation happen to me, mine was also a 14 z51 with 9k miles, mine was bone stock with a d1 procharger with the biggest pulley for low boost, brought it to which I thought at the time was the most well known shop on the east coast to have it tuned and had nothing but problems, blew front and mains seals out and problems with tune, I finally removed the procharger and car still ran really rough, I traded it in for a new z06 and had a friend text me a picture a couple weeks later of the whole car torn apart, wiped out a bearing and needed new engine, I considered myself very lucky to had traded it in before that happened.

NoOne

Another thing was I am pretty sure the shop that did mine dyno'd it stock, not for the numbers but to see if anything was up before they put the parts on.

You were in the situation where you had to load the tune and hope for the best, not someone there watching it, understanding what was going on and could have noticed a problem before it went BOOM.

All in the tune

and for remote tuning pat g did both of my c7s remotely and 0 issues and im up around 700 rwhp AND RAN 10.3@140 AND NEVER EVER USED A DYNO

pat to me is one of the best if not the best

robert miller

^^^ Again if the tuner knows what he id doing really go safe on it then get what that cars is doing with what he put in it. Then redo the tune and put more into it are pull some out from what ever he see's when the guys send that back to him to relook at it.

On this car here by his time slip has to be close to that 700 rwhp # to run a 10.3 and 140 1/4 mile runs. This car for all stock short block sounds like one wild set up. My point is just this. Tune that has been put into the car.

Plus don't sound like this tuner knows much to blow it in the 5,k RPM sound like it is lean with to much timing in it.

Don't get me wrong here I couldn't tune a fart here in these cars. But sure have had 2 bad azz set up's and had both of them to a least more than a number of tuners that didn't really know much of what they were doing at all. Not much more than this guy that done this to the OP cars. Robert
