310racing, how are you continuing to like the Diablo tune on e85? Did you notice your engine sounds louder with that tune? Maybe its just me or maybe since I switched from the mpg tune, which didn't do anything for my truck in terms of better mpg. The Diablo tune feels nice so far.

I am satisfied with it for sure.

I did not notice the engine sounding any louder, and I haven't noticed any mpg increase, but I've added exhaust also so my foot has been alittle heavier.

I would suggest to anyone to purchase, but I got a good deal also.

Filled up with E85 today in Alexandria, MN for $0.89 a gallon! E10 was $1.89. There is a Cenex station in town that seems to always have E85 priced a $1.00/gallon less than gas. I can't see how they are making any money selling it for that but I'm not complaining :)

The 2012 Silverado Reg Cab I had with 4.8 Vortec ran like a rocket with E85. Didn't notice any difference with new truck with 5.3 Ecotec. Guess a little easy on the pedal driving a heavier double cab

Wow. 1.89 for E85 here in Boise, which is the same price as regular unleaded.

Is e85 just plain and simple better ?? I use 87 or should I just u 93 ?? I'm confused as to which is the best

I have a thing against ethanol. I would never buy E85, no it is not better.

Apart from the economics, politics, and myths, E85 is better in a way that the FFV 5.3l engine is calibrated differently for it. The power and torque both increase substantially as GM has claimed and the engine seems to run with more ignition timing and to react quicker (my assessment); throttle tip-in excluded.

Science behind this?

I know right.

 

-Burns cleaner

-Is 85% Alcohol and Gas

-15-20% more Consumption (thats why you get less mpg)

-Higher octane ratings allows our Flex Fuel trucks to run more timing. Equals an estimated 25hp/25trq

-Corrosion myth has been proven false on if used on new Flex Fuel vehicles.

Im on my third tank. Just wondering if It would still be a good idea to run a catch can if running exclusively E85? So far Im pretty pleased with the performance. But around town I drive in M5 or M4 so mileage went to hell. But it seems worth it just for the "crispier" feel.

Yes, it would be a good idea to run a catch can. Especially if you are getting oil build up in the intake. It will help keep it from entering your intake system and causing deposits.

Please don't tell me these new 2014/15 trucks have oil in the air intake hose issues. This has been a headache for me with my wife's 08 Acadia. I'll definitely sick with E85 in the truck if it helps with that.

I put the Diablo tune on in the morning and then with the snow yesterday I was in auto 4wd which I think was the louder noise I was hearing. Ahh, I feel a little silly.

Stealing this quote from their website and being from Michigan and feel strongly about supporting farming I think this is pretty cool. "Last year, Carbon Green BioEnergy purchased more than $80 million worth of Michigan corn from 500 farmers all within a two-hour drive of the facility,.

I'm not sure on the new engines if there is oil in the intake like in our 2011 Acadia and my 2013 Camaro. I'm sure if there is you will find posts of it online somewhere. Sad that it occurs more than not.

So do you have catch cans on your two vehicles? I've been meaning to buy one for the Acadia so I dont have to clean the milkshake gunk out every few weeks.

      OCI, not when but why?

      By Chuck FB · Posted

      That's interesting, I assume that would add to the cost of the oil but also I was forgetting to bring up the issue of the low tension rings allowing more oil past which in turn forces the cats to have more oil additives pass through them that wouldn't otherwise so they are creating that problem and of course its all in the name of fuel economy. Mind you the other issue would be the lack of additives that fight the formation of carbon within the piston ring grooves which turn the engine into an oil burner and with in this GM forums case is your average off the shelf Dexos licensed oil, meanwhile the other off the shelf oil being Valvoline's R&P isn't licensed and the only one that is which is that certain Mobil oil that came out recently ( its not even being marketed in Canada ) and only a fraction of vehicle owners are going to be using it out of all the other oils on the shelf or the quickie lube bay that meet the Dexos spec by way of actual licensing.    Also I suspect that its an easy excuse to pool the non turbo DI engines in with the turbo DI engines and design the oil to not have LSPI issues in the most demanding engines and short change the naturally aspirated DI by not offering a higher concentration of additive package they could handle and still not be at risk of LSPI.    I wonder if Amsoil flipped the switch just lately and did whatever packaging designation at the same time as I wonder what oil formulation I would have bought in May, of course I don't know when it was packaged at the factory vs how long it was in storage at the Edmonton warehouse. I know its been said at least in the past that the big players switch over to a reformulated oil but the packaging has not changed until they make that move as well so there is that cross over time where its a new formulation in a predated formula marked package.

      Hmm. A real reason to not just use the odometer to determine OCI?

      Sad thing is that this doesn't have to be the case. LSPI can be solved without a reduction in TBN. Swap Ca for Mg.  Cats are not a issue if the OEM can get a ring and valve guide seal even at SN levels of SAPS. Dizzy is purring like a kitten with a bowl of warm milk. 200K of Full SAPS oil and zero detonation issues and nice a clean inside and out. This shouldn't be an issue. It isn't 1920.    Tell ya what AMSOIL SS is excellent at, internal cleanliness. The new formula is even a step up from their already outstanding cleanliness levels. Can't say the OEM offering is quite that clean. There marketing suggest the SS is cleaner.     That is the only defense with at shelf oil. Nothing wrong with them if you ignore the marketing and OEM 'recommended' OCI and use a thimble full of common sense. 😉 You go sir.

      Roll up bed cover experiences

      By StingerZ16 · Posted

      I started with a folding cover by BAK PAC on my 2500. It went bad after close to 5 years. Bent and vinyl coming loose. Contacted BAK and they gave me a very good discount on a Revolver. Had it a number of years. Mostly outdoor storage. Some garage storage. Vinyl started to come loose. Still under warranty so they replaced to cover. Sold the 2500, bought the 1500 and got another revolver for it. Had it a couple years now and no issues. I store it indoors. Got a bit of discount when buying it as well. If you are seeing problems, contact BAK or real truck and let them know. Customer service was pretty good. But I think they changed their warranty.

      Towing In Loose Gravel

      By Chuck FB · Posted

      I agree, there is no one answer fits all as every rig is different, one may be pulling some little aluminum fishing boat while another is towing a monstrosity that weighs a lot and hopefully the owner if the rig has some prior experience to know what drive mode they should choose.    It also struck me and this is from watching a few of those boat ramp escapades videos in the past, Ford being one of the vehicles that has the auto front axle hubs and sure enough its found out that one hub has crapped out and won't engage and may not have manual hubs to even select on both sides so they are on the boat ramp stuck with no four wheel drive and spinning .... they flat out need a tow to get up the ramp and deal with the vehicles new found issues. That can happen to all brands of pickup, finding out either four wheel drive or 4 low isn't working right at the time its needed it to work as some electronic crap has failed.
