K&N- got the stock box filter bc the evaporation sensors, etc may act up if you put the external from my understanding from GM Friday. I put it in for other reasons but this was a new one. I also took out the stock air box and replaced it with a straight through deal.

 

As for exhaust, I had a flowmaster on my Titan, this Silvie has a magnaflow and it sounds SOOOOOO MUCH CLEANER! Plus its not hollow sounding and just plain loud, unless that's what you want. When I get into it, you def hear it. Otherwise, idling in the front of the house, its mellow.

 

 

I'll post videos later so you can hear...

My '09 came with a Magnaflow system and it sounds great. On the '02 I had I put a Flowmaster system on it and other than being just a little louder it sounded just as good.

 

As for the K&N 63-3070, I just installed it in Wednesday (4-21-10). It seems to have a quicker throttle response and seems to have better acceleration. No dyno runs to back those statements up, so it could just be me wanting it to be a difference because I just spent $315 on it. I do really think it improved both however.

 

BTW ... don't believe the NO DRILLING required BS ... you have just one hole to drill but it's a 5/8" hole ... I don't wrench everyday so the biggest drill bit I had was a 1/2" ... wish I would've know before I had the stock intake off ... easy install I thought

Might want to rethink the K&N. Their filtering capabilities are extremely poor. They allow all sorts of dirt to pass through.....directly into your engine. Do a search on the topic and see for yourself. I've also talked to other guys who said they installed the K&N FIPK and noticed a little bit of a 'bog' at off-idle acceleration. The paper element filters flow PLENTY of air to supply any demand your LSX truck engine could ask for......but actually filters 10X's better.

I'm not sure that's entirely true. I ran a K&N filter (cone type) on my last truck and did not have any issues with dirt on the MAF or on the interior lip looking thing between cleanings either brand new or when I cleaned and oiled them myself. The main reason (in my book) to get a cold air intake is to allow your truck to breath better. This will help create some HP and give you improved throttle response time (as this gent pointed out) and make your truck work a bit better. It will also help you get back some MPG's with larger or heaver tires installed.

I agree fully, I have had one on my pickup since it had had about 20k on it, now it has 102,386 miles on it and still runs like a bat out of hell, when you push the magic pedal that is! :lol: I did have to replace the maf once, but that was because I was stupid and tried to port the thing myself. Never take advice from the people telling you to port your maf, maybe a descreen, but not a "port and polish" job! :thumbs:

      AFM Disabler Question

      By BlueV8 · Posted

      A complete delete is the most thorough mechanical solution, but it is also major engine work. On a quiet truck that is still under extended warranty, opening the engine purely as prevention is difficult to justify. A plug-in disabler stops commanded cylinder deactivation, but it does not remove or repair the collapsible lifters, so it should not be treated as failure insurance. I would keep the oil full, document the maintenance, and have any persistent tick, misfire, or loss of power diagnosed promptly. If the engine eventually has to come apart, that is the logical time to compare an OEM-style repair with a complete delete. The right choice depends on the truck’s symptoms, warranty status, expected ownership period, and whether the engine already needs to be opened. We explain that decision in more detail here—full disclosure, this is our own guide: https://www.bluev8.com/blogs/news/do-you-actually-need-an-afm-disabler   One exception: some 2021 L82/L84 trucks have RPO YK9, meaning cylinder deactivation was already disabled in the factory ECM; on those trucks a plug-in disabler is redundant, although the AFM/DFM hardware remains inside the engine.

      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.

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