Tuner & leather seats, 17 silverado lt

[raincitysilverado]

Hi, for my new-to-me 17 Silverado LT, I was wondering if anyone uses tuner for certain things. I am not looking for performance gain, just to raise idle from 500 to 650 and deactivate AFM. Is tuner worth it in this case? I was thinking Diablosport. 

Also, does anyone know a place in Seattle area that can install Katzkin cheap? I am looking to buy the kit online and slap them on at the installer but most of them charge 750-900+tax just for the installation, sounds a little too much. Would it be cheaper to find used leather OEM seats in whole as I was thinking of doing center console swap too. 

 

Thank you!

I've been watching a few "full interior" listings since i got my 2018 and they all seem to be $1300-$2000.

 

it's A LOT of work to re-skin an interior, but it CAN be done by yourself.

I use the Diablosports Predator P2 on mine. No complaints. I have AFM disabled, and calibrated my Speedo for 35s. Also running a sport tune that shifts through gears like butter.

I am not exactly handy so I dont want to mess up trying to skin the leather myself. A little scared I'd say. 

 

About the tuner, running tune, does it affect reliability a lot? my only vehicle and daily driver so I'd like to keep it as reliable as I can. It's got 51k on it so powertrain warranty still goes till 60k but this idle thing drives me crazy! GM set the idle too low and I feel too much at idle. Currently AFM is disabled through Range Technology module but nothing I can do about idle till I get a tuner!

No, AFM will reduce reliability, removing it is for the best. As far as the sport tunes I can't say. I only use my truck once sometimes twice a week. I had the same tuner on my old 08 and put a decent 30-40k on it with no issues but long term I don't have that experience

Huh? You got proof of this? There are countless trucks out there with hundreds of thousands of miles on them with AFM (both old and newer designs). My buddies Tahoe was pushing 300k when he traded it in with no issues only doing regular maintenance and no oil usage. A few have had failed lifters which I know will be brought up but non AFM vehicles have had failed lifters too. So just curious if you can provide some proof to make this statement or if this is just an assumption for not liking AFM? Considering you have no long term experience with your own vehicle...

Plenty of proof at dealers and forums. Not so much past 2013 but I don't trust it.

It’s reasonable to be wary of additional move parts involved in AFM. It’s also reasonable to be concerned because of this. Especially being GM recently changed the whole setup. I’m old enough to have experience the 5.7 diesel 62,65. The wonderful 8-6-4 gas engine the first attempt at shutting down cylinders. We owned 4 of the 65s in the mid 90s giving GM another go after owning 3 5.7 GMs. All unreliable. At the same time transmission failures. Out of dozens of family members I started buying GM trucks again in the early 2000s. I stopped after selling my 2014 once the warranty expired. If GM makes a non cylinder deactivation, non turbo engine car or SUV again I’ll give them a look.

No, no proof whatsover, if you discount things like a 55-page ongoing thread of AFM problems on this very website and GM service managers that say "There are 2 types of AFM vehicles: those that already have AFM problems and those that will have AFM problems."  Google 'GM AFM problems' and see how many pages of items you find.  Just because you personally may have been lucky so far, or are too numb to notice if you've had any problems, sticking your head in the sand doesn't mean it isn't happening!

In a round about way, that is great advice, not sure why so many people buy trucks (all brands) that they are fearful of owning, then spend a ton of money to alter them thinking that they will not eventual break.

 

They are machines, they will break at some point, sometimes just a minor thing, sometimes a major thing.

I’ve modified every truck I’ve owned since the 70s, some over 200HP over stock. Never a failure do to modification. My 92 Chevy is stroked, blown and untouched for over 10 years. I can’t imagine a current GM truck engine unmodified doing that. Otherwise I’d still have my 14 GMC.

If you were to go to those extremes, tearing into the engine, and replacing parts, no reason why it would not.

 

I was referring  more to the $200.00 AFM delete devices and things of that manner.

IMO the best way, if you are going to do it, would pull every thing associated with the AFM system out of the engine, and replace it all with conventional (maybe even closer to performance) parts.

My old truck and a few others I’ve owned previously had just added blowers. There wasn’t any other prep needed to make them last. The one mentioned before stroking for more power went over 15 years with just the blower.

To the OP, once you install the tuner your powertrain warranty becomes void.

 

So that remaining 9,000k miles you got turns into 0 miles left. Dealership can and will read the computer before a warranty claim is made to verify that nothing has been tampered with. They can see if something flashed over the stock calibration.

Hey can someone actually provide a good number of all of the vehicles with AFM that have had collapsed lifters? Then let's divide that by the numbers of trucks on the road. Just simple math to get some numbers. 

 

Because the "he said, she said, Charlie Riverrat said, 4000000 pages of AFM failures on the web from 1998-2045", etc. isn't really helping to provide numbers. All the proof that I am getting from the forums these days is that people love to argue on the internet.
