I appreciate the reply Jerseyboy. Yes, the egr and vvt system are 2 different things agreed. 4th Gen don't come with egr valves, I didn't remove one. From my understanding the vvt system eliminates the need for an egr because the pcm controls the valve events at different engine loads, thus determining how much exhaust gases remain in the cylinder to be mix with the intake air charge. Since I never had an egr valve, nor any vvt 4th gen, why is egr monitor showing up on the list of supported monitors on my truck and the trucks I've checked. Once again these trucks with no egr valve have passed the egr monitor test at inspection. The only difference between our trucks is I put in an aftermarket cam?

Thanks AJ for the response. I do realize what you are saying but the heart of this matter is at inspection. The monitor is detected by their equiptment and hasn't run. It doesn't say "not supported" as it should say without the egr valve. Did Mopar forget to delete the monitor from the system? Any other monitor, of the list of monitors that a vehicle could have but doesn't, says "not supported". Just trying to figure out as to why a monitor is showing up on my vehicle that doesn't exist anymore. Also, I checked the inspection report from 2 other rams, a '12 and '15, their egr monitor says "ready". This morning, hooked up my snap-on solus ultra to the truck. Under monitors says egr monitor "test not complete". Went into mode 6, has a vvt system monitor(OBDMID: $35-VVT MONITOR B1), says vvt monitor. Ready: no, vvt system mon. Cycle enabled: yes, vvt system mon. Cycle completed : no. I can easily tell egr monitor and vvt monitor are the same thing with this engine system.

Really interested in knowing why after my cam swap the EGR monitor fails to even function. No codes or issues other than not ready status. I know that my engine has no EGR valve and that the erg monitor is based off vvt system. Is it because the vvt system is OFF, and or because of the duration and valve overlap has changed. I've asked this question to Arrington, AJ and a few others over the course of a year and a half. No one has answers to this basic question.

Sure did. About 2 weeks later after bringing it home. Dismal results. Picked up 17 hp/tq. Admittedly, the truck was having issues against the load of the drum. We discovered this huge ledge, not a dip, @4700-5200. At the time we thought it was the short runner, but turning the runner off makes no change. Waiting for possible SRV tuning see if that make a difference. Cam sweep didn't help, just moved the ledge. Thought it might be a TC issue but the edge is built for 600hp. STR is 2.2 maybe pull it and have it reset. Could be tcm, shift points are less than stock 5600 in original tune. No telling what Arrington, Dave K, if he touched it did. Running these trucks 6400-6800 for shift recovery have caused no problems, no codes. I'm not gaining but still make power through 6400.

He called me from the track yesterday and set me straight! Ditto Cam, he has always been there for me as well. Last time I was in Long Island he explained to me this very issue you mentioned above. Exactly why I feel lucky because he actually tuned my truck, not just his name on the tune, while it was at Arrington, and he has followed through even after Arrington. Nothing but mad respect for him as well. Spend a day with him and you quickly see how busy his world is.

In hindsight, I'm one of the lucky ones when it comes to Arrington I guess. Arrington has had no interest in further R&D of their Cam/Head package. Here you go. It's as good as we can make it type of attitude. Now for the lucky part for me. The tune turned out to be really AJ's tune and to my surprise he has held an interest in continued R&D of the platform. A couple of weeks after I brought the truck home from Va, it too developed a stalling problem, surging at idle. The typical complaints for us with cam swaps in these trucks. Took it to AJ in long Island. By noon, it never stalled or surged again till this day. I did keep the stock rods and lifters amongst some slight protest but upgraded everything else. Everytime I get into this truck, I drive it like I stole it. Around Town on this Island, it rarely sees a gear over 3rd but is no stranger to 6200-6400rpm auto upshifts from 1st and is very comfortable hitting 96mph in 2nd. The fastest I've had the truck is 145mph. 1-2 2-3 upshifts at part throttle %, I've set from 3700rpm upward. Flawless so far. Had the truck back to AJ this May.Put a ported "slightly" intake manifold from Dave W and put a Fastman 84mm TB on as well. Did some modding with LM intakes to work with the Ram hood. AJ did some tweaking and any ST knock, I forgot what that was. Overall, the truck is very fun to drive on the street. Sry this is getting long. I wanna help Sean but I realize this needs to be done on a Dyno, that's not going to be cheap if he's not paying that bill for his own R&D benefits. I wouldn't think there be more than a 5-10hp gain if anything.

So, the guys running the 270, 274 cams, is the vvt on or off?

Thanks Cam. I asked Sean the same question: answered, its a vvt cam so its already designed for a vvt config. and you have phasers which has it's tilt limits. None of the other 266 cams have had issues. But If you have thinner head gaskets and it's a risk then we don't have to mess with it as I won't have info on that

Hoping for some good advice. I was contacted by hemifever last night via email. He wants to use my truck to R&D vvt tuning. I don't know much about the subject but appearantly the vvt system is turned off because of cam and lack off vvt tuning availability. Is that so with the challangers,etc? AJ is the only tuner to work on the truck but he hasn't responded to my attempts reaching out. I'm happy to help anyway I can to the tuning world for the mopar family. Just don't want to slap a piston yet. Is this worth the effort?

Definitly will after the holiday. I'm sure they will want to correct the problem. Perfect!

Vacuum leaks. The tops and bottoms don't seal despite the o-rings. Under vacuum they suck a lot of air, I can actually hear them. Took them out, put a vacuum on them, dunked them under water, within 30 sec. The can filled with water. Just a big vacuum leak. I really don't understand how that could help with getting blow by gases out of the crankcase if they're diminishing effective vacuum. Big disappointment. Not worth the money. Just not what I would expect from a professional performance shop. Maybe I'm not understanding something here.

So, I had this brilliant idea of ditching my BT can for an Arrington V2.0. Go big or stay in the stands. Double Catch Can system. Damn, has to be worth 100Hp. All excited when I get my ups package, from Arrington. Works of Art, I thought, when I pulled these bad boys out of the wrapping. HAPPY, MORE THAN HAPPY! Damn near had an organism. That is till I put some vacuum to them. Both can't hold a tune. Paper weights. Worthless. JUNK! Arrington, hope that $600 helps you in that economically depressed, speed trap town in Martinsville. Good luck with business. Another lesson taught by Arrington, my bad.

Wanted to use Arrington V2.0 on the fresh air side line to the CAI but the oil separator has -8 AN fittings which are way to small over stock tubing 5/8 fittings with 3/4 tube. I have searched hundreds of fittings for a bigger one that will fit in the 3/4" ×16 with no success. My question is can I run the smaller -8AN fittings without issue on that side? Is there a fitting/option that I could use? Something seemingly stupid simple has turned into something of a challenge. Any help would be extremely appreciated.

This is a common complaint with Rams. It only happens with the first start of the day and only in the summer months. True never heard this with the challengers. Some think it has to do with the battery sensor temp charge readings.

HMMM, wish I had the 8 speed. Some of you probably already know the track times the 8 speeds are doing. A lot of 12 sec trucks out there. 2014 RT with 150 shot hit 12.16 @ 110.14MPH. 11's are really close with the gearing. Talk about mechanical advantage. Hemifever really seems to know his stuff tuning these trucks, a lot of meat left on the 5.7.
