Can i run the AFE mouthpiece with my stock intake setup or should i buy the whole AFE intake setup with the mouthpiece? Also is the intake worth the money after up grading the mouthpiece, and what are the benifits of plugging the resonator and re routing the PCV?

Thanks

Looking at buying the aFe mouthpiece myself for a few reasons.

1) LBZ MP-$130 + Silicone coupler - $40 = $170 or so.

2) aFe Mp at Alligator is $195 right now

3) aFe MP requires no modifications or special parts

4) The stock filter works very well.

Add a diy cai mod to the stock filter box is all one should need to have a very good intake system.

Thats what i was thinkin, whats the mod to the airbox you are talking about? Im probably gonna buy all my stuff through alligator, PPE tuner, mouth piece, pillar and gauges and so on.

There are a few variations of the DIY CAI mod that should work well. If you look inside the airbox you'll see that it's open facing the fender. There is a thick foil backed rubber sticker on the fender. If you remove it, there are two holes in the fender well. You can make a boot or use foam to seal the airbox off so that it draws air only through those two holes in the fender. Looks like it might be a little restricting so I was thinking it would be pretty easy to cut another hole or two with a hole saw.

Another method is to seal off the opening of the airbox. Then cut a round hole in the front and instal some kind of large tubing / elbow and rought it down to the bumper area. Some are cutting out the foglight area of the bumper and mounting the open end of the tubing there. I have factory foglights so that won't work quite as well for me.

I did a lot of searching and found several pictures of what others have done and I'd reccomend doing the same. Also look at the Kennedy cai mod and the TXchris CAI mod.

If you have any better ideas, please share them...:)

My afe mouthpiece made a huge difference. Rerouting the pcv will keep oil vapor out of the turbo and cac. As I understand it the only reason to plug the resonator is to make the turbo louder.

I agree,and
As I understand it, a very few resonators have cracked and allowed dirt into the turbo inlet. Even so, I don't think its enough to make me rush to remove it. When I do the PCV re-route and or the MP instal I'll carefully inspect the resonator for any signs of weakness or cracks.

AFE M.P. is definately worth it. It will bolt up directly to stock intake or aftermarket. As far as air cleaners, I dont think there are any that perform better than stock as far as flow. The only way to make it better is (as stated above) make it a cold air intake.

The AFE MP was worth the "seat of the pants feel" for me. Otherwise my induction system is stock.

If you look at the EGR bypass, I think that if you take it off and look at it, you maybe able to make the modifications on your own.

I haven't installed mine yet as the weather up here sucks. But my plan is to do the AFE turbo inlet and the air box mod that's in the kennedy diesel site.

I would recommend the AFE turbo inlet/mouthpiece for your LLY. These mouthpieces make quite a difference over the stock LLY restrictive moutpiece. The AFE mouthpiece will work great with a stock or aftermarket intake kit. I have several customers pleased with both options but several extremely pleased when they went with an aftermarket intake either the S&B or AFE Stage 2si intakes. The Banks intake is very nice as well. The PCV reroute and EGR blocker plates are very good to help keep your engine and intake clean. The EGR blocker plate will keep the soot and recirculated exhaust gases from entering the engine again. the PCV reroute kit will keep the crankcrase from building pressure and keep the oil from the PCV system from getting in your boost tubes, intercooler and turbo. No more oily mess on/in those components. I keep all these items in stock and ready to ship if I can help out. I currently also have a couple USED ppe standard xcellerator tuners that I could make you a great deal on. Just let me know if I can help. mark@bighogcustoms.com

Unless you are pushing over 500HP you wont see much change in the S.O.T.P. feel. This has been documented and reported in the threads covering the M.P. issue. It will however be noticeable on you EGT gauges as well as how your turbo responds to it.

Yeah, I'm sure it's hard to feel even a 10-20 HP gain in one of these heavy trucks. For me it's mostly about efficency. Added with a few other mods should help MPG,s running around and towing my travel trailer.

how much for a used ppe programer?

Check the 'for sale' section for one.

Maybe true, but the turbo did seem as though it spooled faster. And not to be a smart-alec, but who had the calibrated tukas that was doing the measuring?

I mean even with nothing more than a EJA, I have noticed a SOTP gain, and that's no where near the 500 hp arena. Is it just a throttle response change that I am noticing?

Air flows better. Turbo builds boost quicker. Power comes on faster. So it would have better throttle response to a point. Hard to say if you could actually feel any improvement. I have to wait and see when I get mine in a couple months to see if I can feel a differance. Sounds like your happy with yours, and that's good to hear.

Don't know who did any actual testing, but I did read something about it on this site a while back. Don't remember if I saw any actual numbers.

The only advice that I can offer anyone that is, or considering buying one, is to make sure you clean it out well. Mine, came to me with what I would consider a significant amount of casting media. I maybe particular about this, but casting media is not too kind to the internals of engines.

Wash it, boil it, and blow it out. inspect it, and then re-inspect it.

Ordered all my stuff today, PPE xcelerator standard programmer, AFE mouthpiece, autometer ultra lite II pyro and boost gauge with pillar, PCV reroute kit and resonator plug, boost manifold, and 2" keys to add to my cognito 7-9 lift. Next order will be down tube, intercooler pipe and maybe EGR blocker. Should be a fun weekend if it all gets here by then.

Thanks to Aliigator and their friendly service.

Mine came this way as well. It took a lot of sanding and deburring to get it to a level I was comfortable with. (and I am not picky) Then I washed it several times, first with brake cleaner and then with soap and water. It looks like a great design but the casting is rough inside.

Take Care,

OK, i got the gauges and the turbo MP installed last week and i could notice a slight difference. Today my PPE tuner came and i tuned it to stage 3 and what a difference espically when you got to pass someone. Im still waiting for my PCV reroute and the 2" lift keys.

Got mine on also with a modded air box. There is an improvement in throttle responce for sure. Once I do the fpr, ill see how it feels.

I would agree that the difference everyone is feeling is throttle response and not added HP. The turbos simply able to pull air in more efficiently thus resulting in quicker spool. The AFE was quite rough on the inside when mine was delivered, a good bit of the casting media was still loose.

just ordered my mouth piece and resonator plug from alligator lol whats next? my truck is all stock

im a newbie

Pcv reroute. Then egr blocker or delete with necessary software. Then an exhaust and more tuning.

Ya that's what I planned on getting next paycheck

It seemed to me when i installed my AFE, the truck would raise boost a bit faster and i was happy to see the egts go down a bit
