    The Official Vortec 454 Info thread

    Update on vibration: I feel like a dingus. I'm still learning how to truck, and apparently tire rotations make a world of difference. It was a two week wait but my trusty local truck shop finally got me in for a "shakedown" on the vibrations and found no smoking guns. They recommend a balance...

    The Official Vortec 454 Info thread

    Hey guys! Since Tapatalk no longer interfaces with the forum I no longer get "updates" and it's a little harder to use, so I might not get back in here as quickly. In an attempt to increase ride comfort I did the GMT900 rear cab mount bushings and replaced the middle and front cab mount...

    Tapatalk no longer working

    Oh my goodness that's lame... But completely understandable. Thank you for the info gentleman, it has been driving me nuts!

    Tapatalk no longer working

    In researching, it looks like there might be a problem on the GMT 400 forum's end and it no longer supports the Tapatalk app?

    Tapatalk no longer working

    I keep getting the message: "Network error, please try again later (get_config)" tried deleting and downlding the Tapatalk app and still the same. Tried hard reset on my phone and same thing. Extremely frustrating, I love this forum.

    Tapatalk no longer working

    Hey guys, not sure if anyone can help me. For some reason this forum (and only the GMT400 forum) stopped working with my Tapatalk app. Has anyone else had this happen? All the other forums I normally use on Tapatalk work fine, I can't even get this one to load.

    NFab side step impulse buy (K2500)

    So my pregnant wife said she was having a hard time getting into the truck and gave me the green light to spend money on steps. I got carried away and went to my local off-road shop and pulled the trigger without much research other than skimming through here and people saying NFab was the...

    The Official Vortec 454 Info thread

    Hey guys, I'm trying to source new O2 sensors (all 4) and figured the dealership would have the "best" aka non knock off sensors but they're wanting $85 a pop for each one. Y'all gave me great info on 5.0 motorsports for the injectors, is there a preferred vendor or brand for the 02 sensors...

    4 horns?

    Not to scare, but to better perform the function of a horn: get people's attention. Both of the horns were original when I got the truck (23 years old and not working). Replaced them with two new ones that didn't sound even remotely like a truck. Added two more and it does sound like a muffled...

    What did you end up going with for your third brake light? I'm in the hunt myself now for a 1998 extended cab as well Sent from my Pixel 3a XL using Tapatalk

    4 horns?

    I actually went and fabricated brackets and wire splitters to make my 1998 K2500 a 4 horn, but mine is probably a little more redneck than yours. Can you post some pictures? Sent from my Pixel 3a XL using Tapatalk

    Wait, your rebuilt motor already has bent pushrods??? Any idea how it happened? Also: the smoky mountains are probably my favorite place in the country this side of the Mississippi. There are a lot of retired people with big money hiding in those mountains and from what I've seen there seems to...

    1998 L29 454 Torque pro app findings

    I googled "GMC tech bulletin EVO" and found the same link you sent, still didn't work. Think my smart phone ain't as smart as I'd hoped it to be [emoji1787]. But everything you're saying makes sense and puts me at ease about the random unplugged wire flopping around in the engine bay. The...

    The Official Vortec 454 Info thread

    Ok, I'll keep posting questions and observations on my L29 truck until y'all tell me to stop cluttering up the thread [emoji16]. When I got the truck the engine was rebuilt with 160K on the odometer. It was rebuilt with stock spec stuff and the PO had receipts out the wazoo. I have full faith...

    Nope! [emoji1787] Still not working, got a "failed to download" message. I'll have to try it on a computer later. Watcha trying to share, a picture? Is anyone else having trouble with seeing this or is it just me? Sent from my Pixel 3a XL using Tapatalk

    1998 L29 454 Torque pro app findings

    For some reason I'm not able to see the picture you shared. I've had it since January of this year and it has always been unplugged. I did as much due diligence as I could when looking over the truck before purchase. There was a bit of a long and winding story to the truck, but it came with a...

    1998 L29 454 Torque pro app findings

    [emoji15] for the what??? I honestly have no idea what it is, but I'll start learning on what EVO means in terms of power steering. I've read on a Facebook page about a power steering plug that people unplug on purpose but that was for a 5.7 TBI and was in a different location in the engine...

    1998 L29 454 Torque pro app findings

    Hey now, don't you go talking down about my $10 china scanner and $3 app! Very good points all around, and thank you for the confirmation on having heated O2 sensors. Huge help as usual Richard, thank you! Sent from my Pixel 3a XL using Tapatalk

    1998 L29 454 Torque pro app findings

    Thank you! Glad I can stop worrying about trying to find out about oil temp and pressure. Ok, so closed loop is normal for a warmed up truck. Weird, it said closed loop as soon as I turned it on. And fuel system status is saying "Closed loop using 1 O2 sensor (feedback fault)" so I guess only...

    1998 L29 454 Torque pro app findings

    I didn't want to keep cluttering the official 454 thread so I wanted to start this one for anyone looking for or having information on the various readings for sensors and what "correct" might look like. First question: Is anyone able to see oil pressure or oil temperature with their OBDII...

    The Official Vortec 454 Info thread

    I've been playing around with this OBDII scanner and trying to learn what all this stuff means. My REAL question is: which is more accurate/reliable? The $15 scanner from china or the 23 year old dash gauges? I'm finding that the scanner is showing RPM consistently 300 lower than what the tach...

    The Official Vortec 454 Info thread

    I have a cheap OBDII dingus from amazon and I started messing around with the torque pro app yesterday once I realized it might work with the old truck. Unfortunately I wasn't able to get either of the two trans temp PIDs to work, nor could I get the oil pressure or temperature to work (there...
