No dyno numbers from me... I did the mod with very little change in power. It took the BB tune to realize-notice any difference and mileage was unaffected according to my calculations. Slight bump nothing spectacular, so $250 Manifold and TB some minor wrenching it can be done easy easy. I did it because (DID I SAY IT WAS EASY) and only took like 30-45 minutes and that was drinking a couple of beers during the swap.

When I installed the MIT on my 6.2 the increase in engine sound under certain loads was very noticeable. Before I reset the computer the torque increase was really pronounced, & the mileage tanked.I reset the ECM and the mileage has shot back up, and the truck leaned out back to normal.

 

On the airbox mod, I believe it's just as effective to remove the plastic/foam coupler between the body & the box. I did that & could tell it was breathing better. I know about the potential increase in inlet temps, but have not noticed any adverse effects, On my old truck I pulled the plastic coupler and cut up the box similar to how you have yours with a MIT and a ported TB and a BB tune. The truck was way faster. Just saying from a performance perspective, the modded factory box & Airaid MIT gets you to the same or better place than any other cold air for a lot less $$, looks clean, & is effective IMHO.

 

Oh and +2 on ditch the K&N, they suck too much dirt. with the airbox mod above I found dirt (dusting)in the intake tube with a K&N, Switched to a AEM bruteforce dryflow filter and no more dust in the intake. I agree a K&N will flow, they just DO NOT filter very well. When there was no other option(80's & 90's), they were good, now there are many better choices.

None... just like stock. After the tune throttle response was improved.

I swapped intakes this morning and it was very easy and straight forward and only took 1 hr 5 minutes start to finish. Gains.... none that I noticed just a more pronounced sound from the Airaid MIT. I did some WOT pulls from a dead stop and some Interstate WOT blast up to the speed limiter and really no difference.

Now I did take a picture of one of the ports and they all looked like the one posted and the Truck is a year old as of 7-25-14 and has less than 4000 miles on the clock with a RX catch can and clean side separator. I'm sure the Headers, LT-1 Cam and 93 octane Tune will bring everything together were it should be.

 

question.

did you already have the Airaid MIT on the 5.3 intake ? you are reusing the MIT and it fits ?

i have the intake 200-785 .... maybe i'll need a bigger silicone hose / clamp ?

Does swapping to the L86 manifold require any modifications to the PCV lines or system ?

 

Thanks

any more updates that want to add onto this thread? Seems that most results are throttle response. But how much? Or is it mostly a mind thing thinking it would produce results? Thinking about doing this mod with my upgraded exhaust when I go back to tuner to tweak it some more

I've read you wont see any dyno number improvements , because the ecu regulates the power output so much . it has to be tuned into the ecu to actually show any bump in power. this truck doest respond to bolt ons without getting into the ecu tables

 

If you guys want throttle respons you really need to just install the SPrint booster v3.0 , that thing is amaizing, and switches back to stock settings at the press of a button. not bad for $300. I just installed mine saturday and i love it.  took 15 minutes

      Clunk when coming to a stop... driveshaft/slip yoke? Mechanic couldn't recreate it

      By mrbflat · Posted

      I do have the 8 speed.  Interestingly enough, after driving my truck for the past 2 days now, I have not had the clunking issue at all!  I am beginning to think it may have been suspension/leaf spring related, and somehow when the shop put my truck on the lift to do their initial inspection, it relieved some built up tension/pressure that was causing my problem.  I swear it felt I was a bull rider on a bucking bull the way the truck would almost rock back and forth slightly before the big thud/clunk when coming to a stop.  I am hoping I got lucky here and it's gone for good.

      first oil change - 2026 2500HD gas

      Bring it to discount tire. They do free rotations even if you didn’t buy your tires there. I didn’t believe it until I tried and they did. You can tip the employee if you would like

      Best part of this video is how it resets expectations. Wonderfully done piece. It also made clear a few points I've made from day one. Detergent oils DO NOT KEEP A MOTOR CLEAN at the recommended or longer change intervals. They just get dirty slower than a non-detergent oil and there isn't spits difference between them on this point if they carry the DEXOS license. Great thing about the license that gets missed is it assures CONFORMITY even it that means a low bar.    One thing he did not talk about that I paused on an magnified was the condition of the oil ring separator. Besides a stuck ring a plugged separator and land drain back is huge when it comes control. We see in short order improvement in control IF that is the problem.    Another item I took exception to and he did not make plain was the condition of the timing chest and under valve cover having something to do with indicating piston cleanliness. Schaeffer's Oil makes that same omission in their million mile Ford video. I'm guessing he has never torn down a Red Line HP, AMSOIL SS motor that has been on that diet from the get. What he showed in the video was a good deal of varnish. Something totally absent in Peppers 165K cover off look. I smiled because he did his at the same milage.    He also makes the mistake of assuming oil temperatures in the pan are the temperature all over the motor even though he makes note of the piston being the hottest part of the engine. that baffled me a bit.    I can tell you from personal experience and witnessing teardowns of family motors that even oils of the 1960's would keep them squeaky clean when OCI's were 1500 to 2000 miles without exception. At 3K and above you get what he experienced and the longer you leave it the quicker to gets to the junkyard.    I think his is missing a opportunity not tearing it down again when he's done killing it. Time would be his only cost.

      GM discontinuing interior parts on a 5YO vehicle??

      By Z45 · Posted

      Very often the part number on the trim part is just for the vendor order/assembly plant and will not show up in the parts system.  They won't make a bunch of extra parts that were not ordered. Keep in mind, lots of these parts were made to be "just in time" parts meaning they were dedicated to a vehicles ordered and sequenced for assembly.       Also, trim parts will often say, paint to match.
