    Tonyrodz's Tahoe Build Thread

    I did it myself with HP Tuners. I found a stock 2005 tune and used the "compare tunes" feature to see all the differences and then made them. I was intimidated by putting the two pins into the ecu harness but it wasn't that bad. If you have HP Tuners I can do the tune changes for you. With a...

    Tonyrodz's Tahoe Build Thread

    I just did both of my bearing hubs this weekend, bought the 14 dollar air hammer, same one as you. Made the job SO much easier. My drivers went out on Friday, decided to just go ahead and do both. Oh and I finally got my e fan swapped in with an @ScottyBoy harness. Money well spent. Just from...

    Randeez 2012 Budget Yukon Denali Build (stick on hood scoops galore)

    If it gives you any piece of mind, they flushed my 2018 z71 colorado with the 8sp twice and the shudder was still there a little bit. Drove me nuts, a new converter would have fixed it but they were waffling around. I sold the truck anyways because used truck prices were/are insane.

    AC Heat Actuator Blend Doors, 05 Tahoe, SOLVED

    Thank you for that! I put my info in and printed off the list of software calibrations for my manual dual zone system. Going to run it by my dealer friend who has a tech2. Just an fyi for anyone with these issues. For the 2004 dual zone manual system, there are three new calibrations.

    Fuel Pressure Regulator Vacuum Line

    Thank you @Fless @rockola1971 and @915_Tahoe for the help and info!! I am in East Texas. Bummer it's discontinued. Hey at least it's some closure, ha. Probably not worth looking for in a yard with it being old rubber. Mine acutually looks great until you bend the elbows. I am just going to...

    AC Heat Actuator Blend Doors, 05 Tahoe, SOLVED

    My 2004 has done this exact same thing randomly 5 or 6 times since I bought it back in October of 2020. Drivers side only will suddenly get hot. Not hot like hot outside air, but actual heater air hot.....friggen super hot. If I run my hand over to the passenger side it's still ice cold coming...

    Rocket Man's 02 Denali Build Thread AKA "THE BEAST"

    You scared the heck out me with that one! Congrats on the trans fix and happy to see you get into your own tuning. I have really enjoyed the process of learning and tuning with my MPVI2. I have only done trans stuff so far since I don't have my wideband yet. I don't feel comfortable with tuning...

    Fuel Pressure Regulator Vacuum Line

    I can't find the correct line for my flex fuel 2004! This is the line from the top of the intake over to the fuel pressure regulator. The issue is that the flex fuel vehicles have the nipple coming out horizontal vs upright nipple configuration (giggity) on the non flex fuel. Non flex part...

    Rocket Man's 02 Denali Build Thread AKA "THE BEAST"

    Dang! Hey at least you garnered a few more clues....hope you find it. Since other systems went haywire, I would try grounds first since that is probably easier than going through the harness.

    Rocket Man's 02 Denali Build Thread AKA "THE BEAST"

    They work by DC current producing a magnetic field to make the switch move (hence the copper windings). Trans fluid won't keep the magnet from working on a circuit like that, but when fluid leaks into the harness where ALL the pins are in very close proximity to each other, see that could cause...

    Rocket Man's 02 Denali Build Thread AKA "THE BEAST"

    Correct. From my limited knowledge, fluid inside the connector (outside the trans, but both male and female parts) can cause a lot of problems with these electronic controlled transmissions. It's not something you should just clean out and it's GTG, if it's leaking then the potting/seal is bad...

    Ole 2 Speed

    Don't forget to lightly scotch bright the surfaces the sprag bearings, piston seals and pump rotor/veins run on. Helps reduce friction by allowing trans fluid to build on the surface. That "precisions transmissions" guy I have watched a hundred videos on harps on this a lot. "Scotch bright is...

    Rocket Man's 02 Denali Build Thread AKA "THE BEAST"

    Just remembered something. It could also be an issue with the wiring harness...which would likely be fluid in the connector plug. Might be a good idea to undo the connector and look closely inside the end of the plug. If it looks wet, the harness should be be replaced. If that's the issue, the...

    2004 6.0 NV4500 Tahoe

    I literally almost wrote the exact same thing. I love the way the exhaust sounds on turbo LS motors. On a side note, in high school in the early 2000s, one of my best friends saved up all summer for a janky turbo kit for his old acura integra. Helped him install and actually tune it! We didn't...

    How to turn on fans with HP Tuners

    I found the settings. See picture below. These are the settings for 2003 up. For pre 03 you are going to have the different pin setup into the the ECM but the only thing needed different from these settings is to change the setting under AC for "recirculation fitted" from Fan #2 like in the...

    2004 6.0 NV4500 Tahoe

    That looks much better! I prefer quieter exhausts now that I am older. Not sure what happened to me other than my tastes changed.

    Rocket Man's 02 Denali Build Thread AKA "THE BEAST"

    Weeks for BB to get back with you? I think you have a good chance it's the solenoid since the performabuilt was probably built with all new solenoids. Sounds backwards but I have heard the new aftermarket ones are hit and miss compared to the original solenoids.

    Mild 6.0L Build Suggestions?

    That's interesting. I wonder if there is a way to log the suspected 2/4 slip with some math parameters set up like I have seen folks set up scanner to log TCC slip? Here in a bit I'm gonna snap a pic of my PE settings and also my knock sensor settings. Would be interesting to see your knock...

    OR VietVet Is Still Throwing $$$ at 2005 Z71

    @PNW VietVet When are the engine/trans performance mods scheduled? :) I am hoping that after you get your tune done, you will get the bug to do more.

    Welcome! How easily are you going into power enrichment? Ever since I lowered the threshold to enter PE through the rpm and MAP I am getting into PE/ open loop a lot easier and it really scoots well now with less throttle....and it's 95 here. I'm not logging any knock retard on stock tune...
