i know the Duramax better than the Vortec, what are Gibson Shorties ?

 

I have a Dual 3" Free Flow Exhaust, i'd like the intake stock though...

Magnacharger...IMO the best bolt-on and troublefree supercharger system out there. I wouldn't bother with shorties...go for long tubes.

Shorty headers. They bolt directly into place without modification. I have a friend who did it on his 2500 with great results. Whether people want to believe it or not. He tows regular 8600 lbs with his 2500 and noticed instant improvement.

say i'll be going with Hooker shorties, the Magnacharger and a mild cam to go with it....

 

what horsepower should i be expecting ?

 

am i right that everything from a 5.3 will fit on the 6.0 as they are both LS1 ? or am i just talking shit here ?

If you are going to get headers, you might as well go with LTs or just stick with your stockers. The shorties do have a gain, but it is minimal compared to LTs.

 

Here is what I suggest to folks wanting to upgrade their trucks:

 

Stage One: intake, exhaust, tune

Stage Two: cam, headers, efans, gears

Stage Three: blower, transmission, torque converter

Thanks on the advice, i think your plan is just about close to what i have in mind, but i'm not a fan of these oil lubricated air filters that kill my MAFs....

 

However i have a another question, how do i determine wich motor i've got.... what are they called LQ4 and LQ9 or something ?

 

Remember it's a 6.0 Vortec...

I don't think you have to worry about most intake filters getting gunk on your MAF, it is usually operator error when someone will "recharge" their filter. The MAF, however, is easily cleaned and should be cleaned even without an aftermarket intake filter.

 

You have an LQ4.

Ok, i know the speedo is off, but here is a video of the acceleration after fitting the 33"...

 

I feel it's sluggish :)

 

Truck has 4.10 Ratio (GT5)...

Yes it does seem that way. A tune would help that a bit. The 33" is where some of the sluggish is comming from, the rest is from the TM.

 

Does my truck have a 4L80E or a 4L60E ?
4L80

I don't want to go with the Hookers as the are specified for the 5.3 :cool:

 

so i'm asking if anyone has any experience with Hedman Headers ?

 

I'm looking at a pair of these for 300$...

I want a streetable truck so i don't know if i'll be going with a cam, but i'm looking into the Magnacharger Radix.

 

How many horsepower can i run through my 4L80 before i need to build it to specs ?

 

I want to run maybe around 450-500hp with lots of TQ... are these maybe too crazy numbers ?

 

And what about heads ?

 

If i go for this pack:

Wich should i buy ? drive by wire or cable driven ?

      Help purchasing a touch screen digitizer

      By mark249 · Posted

      Brought my 2015 Colorado into the dealership to check my touch screen issues, had that ghost touch thing happening. They said I needed a new touch screen and they could either order me one for $500. The lady at the service deck was nice enough to tell me I could order a touch screen online for less, she did stipulate that the touch screen had to be factory OEM, you can't pair an aftermarket screen to my radio seeing it was 2015, it had to be a GM factory OEM only. I found a few on Amazon and Ebay by the numbers on the back of the old screen, DJ080PA-01A GM# 22740886, Some said "OEM" in the description and others just said "Replacement". Would a replacement be the same as a OEM as long as it had the same numbers on the back of the screen? In some of the descriptions they also show different brand names but same numbers, is that an issue?

      I have both but typically use the 4 legged walker (wheels on front, ski's on back).   The four wheeler is starting to be used on "longer" outdoor walks.  The 4 legged walker is particularly helpful in practicing good walking posture.  Both of my knees are at different stages of recovery and I'm trying to not develop poor habits.  I can actually manage with a cane but it's very difficult not to favor one leg over the other.  My PT recommends I continue with my 4 legged walker for a while.  Yesterday was four weeks since my last knee replacement and I'm excited about my progress to date.  It has been a hell of a rough journey so far but it is exciting to witness  systematic and continuous improvement.  I went for years watching the decline of my "mobility".  It seems that everyday now I am alerting my wife to something I can do now that I couldn't a day or two ago!  I encourage anyone facing the prospect of knee replacement to share any concerns with others who have had the surgery.  It isn't an instant fix but rather is a considerable amount of short term pain for long term gain.  Recovery time and pain levels vary for individuals post surgery but the end results are typically very positive and I've never encountered anyone regretting having had the surgery.

      AFM Disabler Question

      The lifter issue can be dealt with by shorter oil changes and quality oil IMO.

      Wiring Help, Please

      By Core-Lokt · Posted

      I'm putting in an A-pillar pod/gauges, and I'm asking if anybody can identify a (preferably) fuse for a switched power and illumination circuit on the driver's side interior fuse panel. Offhand, everything I checked with a test light was constant-hot, and I'd much rather uses a piggyback fuse. I can certainly find a wire, but I'd rather not half-tap.   Thanks in advance for any help.
