So I finally decided I'm annoyed enough that my tires are larger than stock which causes my speedo to be off and my truck to run higher RPMs and struggle to shift right sometimes. So I am buying a tuner from my shop who did my lift/ tires.

They recommended a hypertech so that's what I'm going for. 

This is what I'm looking for. I dont care about the who being the fastest, loudest and biggest HP truck out there at all. I bought the V6 for a reason. So what I WANT is the best economy while not driving a slug. 

Note- I have zero desire or plans to do any engine or exhaust modifications. I dont even really plan to do a cold air intake. I'm content with the way things are. 

The hypertech comes with the 3 standard tunes. Obviously I'll be using the eco one mostly. 

From what I understand I can turn some things like the AFM on and off or adjust it too. 

So what things would you adjust to optimize the mpg while still having something that doesnt feel like a slug to drive. 

I am brand new to the tuner world and not exacrly sure how these work.

Inwould not buybthat tuner. I respect what you are saying. That said I would get a HPT. You new ones are cheap and work on unlimited vehicles so you can really get your money out of them and the support is 2nd to non. You can post files and people will help. There is also a forum and pre built tunes.
Night and day difference. All pros use HPT or efi live.
Please look into it.
I can help you with tune questions and settings along with screen shots or file share.

I had a Hypertech I used on my 4.3 v6.

 

What I used was stock engine tune, stock rev limit, stock shift points, stock firmness, sport throttle response, sport shift response, street tcc slip, v4 mode off.

 

With the 87 octane tune you only get a peak of 4 horse and 2 ft lb torque gain. The 93 octane tune gives you 8 horse and 8 ft lb torque gain.Their dyno graph starts out at 2750 rpm. Probably don't want to show you anything lower cause it loosing power.

Did you mostly run the 87 tune? How was the MPG increase?

What made you choose those settings?

Also look in vehicle build for grumpy bear post he is the know all around here for fuel economy. It will help you understand many of the why of things.
There is much that can be done in trans and slip. Then in engine v4 disable and command over shift. Also depending on your state I like to play with the engine coolant and fan percentage. There are talks of the importance of mods but hard to recommend not knowing your skill level, fuel type, and current mods. Also hpt can read,block, and erase codes as well as data log.

You just buy the small non pro plug in and credits and go to town. Data a file and post it for others to mod. Or if you wish you can go to any tuner around and he can use yours.
There a hundred of screen shots,videos, and posts on how to use.

I ran the stock factory tune. Cause there was no mpg increase with the other tunes.

 

The shift points only change at wide open throttle. Don't see a need to change them or rev limit on a stock engine.

 

The shift firmness on street or higher is way to hard in my opinion. Cant be good for the transmission in my opinion.

 

 The throttle and shift response felt good at those settings. 

 

I also had a Superchips tuner. Did not like the 2nd gear shift.Felt like the truck was getting rear ended.

      OCI, not when but why?

      By Chuck FB · Posted

      If all oil manufacturers had to meet a higher standard for not just the initial filtering of the oil but that they had to improve on their formulation so that the oil cleaned the engine such as the Valvoline R&P or the new Mobil product ( assuming it works similar of course ), and the oil was changed on an interval based on good UOA data, there shouldn't be any gremlins running around like miniture rats on top of your heads to be washed down into the oil pan below 😁

      OCI, not when but why?

      A while back on another thread there were comments and thoughts on air filters and I know that can tend to be a bit of a hot topic because of outfits that have a vested interest in selling aftermarket air boxes fitted with the gauze type of oiled elements touting the lower air restriction. However and unfortunately I don't know where I have seen the test results in the past about the amount of dirt through a test procedure that these style of filters do pass more dirt through than a properly designed ( not some cheap Chinese knock off ) paper/synesthetic media filter can do. Lake Speed had a conversation on that topic with one of the employees at Donaldson and there seemed to be a consensus of these oiled filters falling short in the absolute percentage of dirt holdback.    Which all ties back into how good the air filter is on the engine at keeping dirt out as that is going to reflect as a contaminant introduced into the oil as well as cylinder wear even if some of that dirt does find its way out of the exhaust rather then the crank case. Put another way that one can throw the kitchen sink at filtering the oil and using a bypass system which I fully expect will do nothing but good for the oils contamination but if the air filter system isn't doing its job then its preventing the engine from reaching the best wear/lasting case scenario instead.    Now perhaps this topic is or isn't for this particular thread but Grumpy Bear or anyone else for that matter, do you have access to some scientific trust worthy testing on engine air filter types to get some proper comparison data to post up.

      WOW, something we agreed on. I only bought at sticker twice. A 94 impala ss and an Acura intagra type r. Made money on the first. Still have the second.

      I prefer new, but not without a deal. Historically I've bought severely aged new inventory, leftover model year, unpopular configuration kind of stuff that sits around on dealer lots until they just want it gone. $10k off MSRP kind of stuff on a mid-priced truck. That really, really helps knock down that first year depreciation. It also requires being somewhat flexible on colors and options. I wouldn't buy a 4 cylinder if I was looking for an 8 cylinder, but if I got blue paint instead of black, or a great deal was lacking a minor option, I'm willing to overlook those things for savings.   Used <> used. Condition and history are everything. If I'm buying used I'm looking for cream of the crop. The truck from the guy who religiously pampers it, and then decides a year later he wants newer and nicer. NOT the ex-rental vehicle, or the crew cab traded in by the family with 7 kids who like to throw food, and the oil only got changed when there was time long after the oil life monitor started alerting.
