   Hey guys I’m new to the forum as well the brand. I recently just bought a 2019 custom trail boss which only offers the 5.3. I wanted the 6.2 but that came with only the higher trims. I’m familiar with the 5.7 hemi and I’m kinda down about the 355 horsepower/ 383 torque compared to my hemi that I traded. What can I do exactly to get more power to the engine?

Bet he meant 5.0 FORD or 5.7 DODGE HEMI.    Okay, back to my popcorn. 

I went with the 6.2, so I don't have to worry about having a slow, weak truck.  

My truck isn’t slow or weak. It also doesn’t require premium fuel and gets better mpg. 

Yeah man I just had the 2018 ram 1500 bighorn and the 5.7 was a beast but it was a quad cab so no good for my growing family. I was trying to buy another ram but A crew cab 4x4 bighorn was about 45,000 they wouldn’t budge either the lowest I got was 43,000. Chevy offered me the trail boss for 43,000 and I like to go off the pavement and the price was something I couldn’t turn down. Plus ram was only giving me 21,000 for the truck Chevy gave me 26,000

Only a supercharger or turbo will give you noticeable gains without replacing engine parts. 

 

Headers and a straight through muffler would help but won’t be near 45hp. Maybe 20-25. 

 

Not to mention replacing the exhaust manifolds with headers would raise warranty related eyebrows concerning the heads and exhaust. 

 

There’s the 6.2L intake manifold and throttle body swap. Less than 10hp though.

You're pretty much out of luck on anything that adds horsepower because there is no way to calibrate it for the changes. Not even swapping to 4.10's can be done yet.

The cool part about doing the 6.2L intake swap is that it moves your TQ and HP curve 400ish rpm lower. Better low end.

So for you guys that have been with GM for awhile what makes you pick the 5.3 over the 5.7 and 5.0? Just curious. Has the 5.3 been that reliable? 

:lurk:

 

And I have a front row seat!!!

The fact that GM no longer offers the 5.0 or 5.7 is the reason folks pick the 5.3.  The 5.3 and the 6.2 are the only small block V8 options at this point.

      I have a 2000 Silverado 2500 6.0 that is having some hesitation/cutting out on acceleration. It’s weird it seems like if you ease into the throttle it doesn’t cut out but if you mash on the gas it acts like it wants to die. It does it in park and in drive. First noticed it when I was pulling my boat out of the lake and I could barely make it up the boat ramp, it was spitting in sputtering until it eventually seems like it cleared up and started going normal. I replaced the spark plugs, spark plug wires, fuel pump, fuel filter, ran seafoam through the gas, and change the air filter but it seems to not of helped there’s also no check engine light. What could be the issue, thanks!

      Ok so I have a 2015 gmc sierra 1500. after backing up and putting it into drive I get going for about 5 to 10 seconds ill get a jarring lock up for a split second. First time it happened I was going about 40 and I bounced off the steering wheel and left a little skid mark. It sounds like either my transfer case or transmission is locking up but it literally lasts for a split second then goes away. also I've noticed that after shifting from reverse I hear a loud transmission whine before it does it. This has happened at least 30 times for about a year and dealer says they can't recreate it.
      It's the 6spd tranny
       
      Also I know all about the normal GMC transmission clunk when shifting I have that too but I've learned to live with it. This is something else entirely. Its dangerous and I can't find anything on any forum mentioning this issue

      Recently replaced plugs and wires in 2004 Chevy Silverado Z71. It now idles very rough almost to the point of stalling and misfiring. I found a forum somewhere that mentioned wrong plugs but now can't find it to show the hubby. Any help is appreciated! Love these forums!

      Hey y’all, new to the forum and to chevys here (used to drive an 84 Jeep CJ) and bought my K5 a few days ago
       
      off the bat it came with a few problems the guy who sold it told us about, he said that the brake light bulbs would pop while driving, but we took it home (had someone drive behind us) and confirmed that we don’t have brake lights (the bulbs are not blown) or turn signals (front or back) and when we got home I confirmed that the backup lights and hazards (all four corners) do not come on either. And this didn’t happen when we first got it, but the morning after I found the interior light on and had to take the bulb out (wouldn’t turn off) in the fear of running out the battery
       
      however, the taillights and the dailys (I’ve heard those little yellow lights on the sides called that before but I don’t know if that’s the proper term) do come on when the headlights are turned on. 
       
      ive checked the fuses for the brakelights and turn signals and nothing seems to be wrong with them, so I’m assuming there must be something wrong in the steering column, but I’m at a loss of how to go about fixing the problem, and I’d love to get some advice before i go about taking the thing apart or having a shop look at it.
       
      anything is greatly appreciated, thanks!

      Hello anyone/everyone,
       
        As mentioned in the title, i would like to perform a front seat swap in my 2007 Chevy Tahoe with some seats out of a 2015 Yukon.  What I’m really looking for if there happens to be a bracket out there that already exists so I can be lazy and not have to build one. Thanks In advance
