Problem with the cylinder deactivation is, you can't disable it. Start stop can be deactivated by pressing a button, putting a trailer tester in the trailer plug or jumping out the button. The cylinder deactivation is built into the engine, nothing you can do about it. For that reason, I'd rather have start/stop than the cylinder deactivation.

 

Being in a rural area, that doesn't bug me. It almost never shuts off because my drive to work is 25 miles and most of the stops are near home where the engine is still too cold for the truck to let it shut off.

I love my 2.7. I'm thinking of going 3.5 next time only because it's about the same price in the end. The 3.5 has a max tow package with the rear locker, larger fuel tank, brake controller, and all of the stuff in the regular tow package, and it's only $300 more than the regular tow package. Adding those options individually like you have to on a 2.7 ends up being around $1k higher.

 

The cyl deactivation in my GMC doesn't concern me much at all. You would never know it's happening if you don't have the gauge set to that screen. But that grade braking? Holy crap, the first time it happens you will think you just blew up your truck.

 

The cylinder deactivation torpedo'd my dad's Tahoe. It had 150k miles on it, not the norm but I'm not a fan of those systems, I prefer ones I can disable if I want to but I have a feeling I'll have to get over that in the fairly near future.

 

I have start/stop on my JL and I haven't minded it so far. Granted, I haven't driven it in traffic yet. I'd probably shut it off during stop and go traffic. Also, my 8 speed shifts less and smoother than my 3rd gen.

 

I thought you could disable some going into the ECU?

If I go with a ferrrrd in the future it would probably be the 2.7. I don't tow enough to justify anything more than that.

I didn't know about the grade braking, good to know. Sounds miserable.

Yeah that's why I'm not a fan of the deactivation, it borks crap. I think you can disable some of them in the ECU but it's for sure not a button press.

The Auto Start Stop.....ASS.....early on was bad because it didn't disable with A/C on, etc. so you'd be sitting in stop and go traffic and the car would turn into a furnace. I THINK Dodge has the ASS on the new trucks, I'm not sure about cylinder deactivation, but they do have the "mini hybrid" that can take the truck off the line. I mean it's only like 100 ft capable but it's enough to not shut down the A/C and the engine doesn't need to restart before you can hit the gas. I do like that.

 

I'm sure you can, but the engine internals are made differently to accommodate the deactivation. When towing, I know cylinders won't deactivate but the parts and pieces that cause the deactivation are still all built in. It's not a simple programming thing like it is with auto start/stop. I believe that's why @Noelie84 went with the 5.7 in his Ram 2500 vs. the 6.4. The 6.4 has the MDS which is cylinder deactivation.

 

Hmm, didn't know it was built that much differently. Good to know! I really don't know much about it because I hate it.

 

I don't know all of the mechanics of how it works, but the cylinders being deactivated stop receiving fuel and the valves stop operating. The fuel is just programming but the valves means something is happening with the cams. It can be overridden but it's all still there.

 

The cyl deactivation on the GMC still happens when I'm pulling even in tow/haul mode and even with a trailer attached.

 

That's weird programming. My F-150's auto stop is disabled when a trailer is plugged in, when it's in 4WD, when it's in sport or tow haul mode, basically any situation where you probably weren't going for economy. I figured the cylinder deactivation would have been similar.

 

I'm glad my Tacoma doesn't have any of this start/stop or cylinder deactivation crap. Just more stuff to fix/replace down the road if you keep your vehicle for a good amount of time.

 

Honestly, no new vehicle these days seems to survive their first year or two without some significant tweaking needed. The 16' taco's didn't do so well until a few updates on their shifting.

 

Wow, that's interesting. I wonder if that changed, I thought tow/haul mode killed the deactivation.

Oh, just wait. Pretty soon it's going to be hard to avoid it.

You see the new Ferd 7.3 gasser? Thing's a beast and actually seems to be doing really well for it's debut. I'd absolutely love to have one!

 

Nope. All my buddies trucks do it in tow/haul mode. But I honestly wonder if it's doing anything at all. You hear nothing, you feel nothing, I don't think my mileage would be any worse without it... the only indication is on the gauge when it happens. I guess unless you got an uncle with a Tahoe that has it... you fell something when it goes south.

Just got back from the RAM dealer, got my eye on a Grey '20 1500 BigHorn Sport with the 5.7L V8. Real nice looking anyway. Gonna drive it tonight after work.

Yes I did see that new 7.3, and it is tempting as hell. It sounds like the perfect motor now that diesel has been kneecapped so much. If I were going HD/SD thats really the only one I'd even think about right now.

 

oh @Pugga I am going to get the borla exhaust, they said it doesn't come with gaskets. Do I need them? Where would one find something like that.

@Unchained 5150 did you have to add anything for yours?

Thanks guys.

 

@crashngiggles did mine but I don't believe we added anything

 

That thing would look awesome with black wheels!

I still like the 6.2 and would like to drive one with the 10 speed rather than the 6 speed that I have. Only problem is, you can only get the 6.2 with the 10 speed if you jump to the F350, can't get it in the 3/4 ton flavor. The 7.3 is a nice power plant and getting very similar mileage to the 6.2 (better towing economy in some cases).

Not sure how your Tacoma is configured but I did not need any gaskets when I installed the Gibson system on my truck. It came with u-bolts to join the new to the old but no gaskets. Unless you're replacing headers, I can't see how you'd need any gaskets for a cat-back system.

 

Sounds like I don't need to worry about adding anything. Thanks guys!


Maybe the 7.3 fits in my 1st gen?
