I'm guessing your performance programming changes voided GM warranty - it records all in the computer even if change back to stock before going to the dealer.i was wondering if anyone else has had problems with lmm injectors and gm not wanting to help, if you know of anyone that has tell them to pm me if you dont mind
So tell me again why this is GM's fault, and why they should pay for it? You put a programmer on your truck and were going well above what the truck is governed at, so how is it GM's fault?
I can't understand why you'd even try to have GM fix it under warranty.
You're probably lucky that it wasn't a tire that blew. 37's and 120mph don't mix. I'd bet those tires aren't even rated for 90mph. That injector might have saved your life!
Bottom line, you and everyone else knows that any programmer will void your warranty. You put one on, and broke your truck, so you have to fix it. Pretty simple. Whining that GM didn't pay for it for you will fall on deaf ears.
Ask anyone who has ever broken anything and they'll tell you. You have to pay to play. :read
And as to your question, I've never heard of any troubles with LMM injectors, your case sounds like a freak incidence. although the mp8 is a pressure box which doesn't help things.
they pulled the piston and injector and replaced them, the cylinder walls were not harmed at all and the trans is getting some more upgrades. total bill motor 4k and trans is around 4500i am more curious, how much was the bill? did they just put a new piston in or a short block or a drop in?
are they sure the walls were fine? ive heard from many builders and all of the have said that they have never seen an engine with a cracked piston have not have to be bored out...they pulled the piston and injector and replaced them, the cylinder walls were not harmed at all and the trans is getting some more upgrades. total bill motor 4k and trans is around 4500
