Got my Corsa sport cat back installed and dyno tuned. Fully exceeded my expectations with the sound and ZERO drone. Pulled 30hp over stock with 91 octane. It is a completely different driving experience now and it's perfect. 5.3 quad cab LTZ 3.42 gears. Sent from my iPhone using Tapatalk

When Chrysler first brought out the lockup convertor in late 70's it was basically a hydraulic clutch. I had a buddy that was running a 69 340 Dart with a 4 speed and 5.38 gears. He had a hard time getting the shift right every time. For some reason, he would move both arms when he shifted, the 1-2 shift was also a left turn. He wanted me to build him a 727 with manual shift valve body. He was a machinist/millwright with access to the necessary machines. Between the two of us we built a 727 with manual control over the convertor. These transmissions have zero electrics in them. Broke a few converters on the 1-2 shift at 7200rpm. Car should have had a higher stall convertor, but, that seemed counter-productive to me. With the gears, and light weight, engine was not long at low rpm anyways. Weak point was the convertor, but the "never miss a shift" convinced him to go to a clutch-flyte trans. Now that was a slick setup.

Seriously doubt that GM went to the Global A system and didn't do flash counters. Probably just said that because otherwise might scare folks off.

The guy at the dyno shop verified with GM there are no flash counters in 2014 models. They will start in 2015. Sent from my iPhone using Tapatalk

The warranty scare doesn't make it an easy choice, that's for sure. I'm going to do my 6.2 anyway though. I'm weighing the odds (or what I guess them to be) of having a major powertrain failure and having the dealer (successfully) deny warranty coverage for it due to a tune that did not cause the problem... vs. the joy of ownership improvement over the next 5 years of having a properly calibrated speedo, better throttle response/drivability, better mileage and more power. I'm guesstimating the odds of the former being relatively low, or at least not high enough to keep the vehicle from working the way I want it to work. Only time will tell if it's the wrong choice.

The power train warranty will be blocked/voided if it goes in for service of internal engine and or transmissions components. If for example the alternator or other engine accessory goes out they may not check the codes and replace the part under warranty. At any rate it's always a risk but then again if you start getting nickeled and dimed in repairs you could trade it and get a new or slightly used one with warranty. My guess is that a tuned truck driven within reason will be ok. The 5.3 gains nearly 30 hp and tq with E85 so I think the drivetrain could handle a tune without issue. Chevy engineers are missing out on extra cash if they offered factory tuning which didn't affect warranty. They could offer stock, mild, and wild as choices.

Yeah they specialize in Ls engines and swapping them into just about anything. They have a 350z with a Ls9 swap and brog warner 67mm turbo making 780 to the wheels. And a 95 BMW 3 series also Ls9 swap all motor 600 to the ground. To many crazy builds to list But yeah I've only seen the 6.2 tune thread. Sent from my iPhone using Tapatalk

Just got mine last week!

At least you get a ride to work every day. I get stranded in the middle of nowhere when mine wont start haha

I have 3.42 rear end and I have vibration as well.

I think I have it figured out now. GM has developed a updated version of the mood ring (some people on here may not be old enough to know what a mood ring is they can do a google search if needed) and your new 2014 truck senses your mood. If you are a crabby old fart today you get very little V4 , if you are kind to young children and pet the dog instead of kicking it the truck senses that and gives you lots of V4 and better gas mileage. Watch your MOOD swings bichs. LOL

It is not. My wife's car works flawlessly and the loaner I got never dropped the signal,not even under a bridge.

Debadged the truck....

thewhitestalion, well you convinced me ,,,,,,,,well sort of,,,,, to stay with the black window moldings. I think adding the chrome would be too much, probably the same reason you removed yours. Here are pics of my new Silverado, day I brought it home 3 weeks ago and today. I think accessorizing is complete. Well, maybe ...LOL.....WIndow tint is next. 20% over the back window and 35% on front doors....
