I wish there was someone near St. Louis that did dyno tuning like this. I'd love to tune my truck but don't want it done remotely based off of what my parameters "should" be running at.

What made you decide to go with 1 3/4 vs 1 7/8 headers. Thanks for posting the dyno numbers, wish I could see a comparison to a set of 1 7/8 I'm trying to decide what to go with for my other wise stock 2011 6.2 I am running a black bear tune

I know you posted this a while back....If you would like to pm me I should be able to get you a couple names of people locally that can potentially help you if your still interested.

There isn't much difference with the two, the 1 3/4 will give a little bit more low/mid range which is what I would consider more usable with this application (truck).....if this were a car with an LS powered 6.2 like a corvette or camaro it would be 1 7/8 every time as there isn't enough of a difference not to take advantage of the few extra hp/tq in the mid/upper rpm's.

I hear ya there!!

 

Dave Steck did all my tuning in the past, I'm sure your aware that he moved to TX but I know he offers remote tuning as long as the person has access to HP Tuners or knows someone that does.

 

There is a local guy named Jake Batz that is a bit of an unknown, he is good with NA applications but I'm not sure if he has the experience with tuning transmissions?

 

I will reach out to him to see what he says and let you know.

 

Have a great 4th!

I had Dave tune my last couple trucks, and he's tuned umpteen of my friends' drag cars. What a bummer when he moved, but man was I glad to hear that he's starting tuning for us peasants again. Dude is like a wizard. I've actually heard a little about Jake. Shoot me a pm when you hear back from him. Thanks!

300whp and 330lb-ft at 1750rpm with a naturally aspirated small block on 34's is kind of funny to say the least, those are above peak numbers on the early Gen III-IV LS family 5.3L. Congrats man.

Better results than I expected, congrats! I'll be doing the same to mine hopefully this winter.

 

- Stock wheels / tires: On a 2WD street truck changing from 20's to 24's I saw a friends truck drop 30whp on back to back pulls last November, however that was on a 5.3 with same mods as yours w/E85. I'd think your 20x10's & 34's are likely costing you 15-20whp.

 

- Regarding a post above referencing E85, the 6.2's don't have as high a CR as the 5.3's so the gains won't be as much which explains why GM doesn't have an E85 tune loaded. With a belt driven intake manifold, E85 would deliver the goods !

False, the 6.2 has a higher compression ratio for sure

 

its either half a point or a full point higher

You are correct, since I posted that July last year I learned the 6.2 is a half point higher at 11.5:1. 

I'm curious as to why the 5.3 is rated from GM to produce more power with E85 and the 6.2 is not (especially with the higher CR).

The 6.2 is not e85 compatible from the factory. That’s probably why it’s not rated higher with e85.

      2015 Silverado 3500 right rear turn indicator failure

      By davester · Posted

      consider doing electrical testing?  I would guess some power or ground wire/connection has a problem.   alldata.com has wiring diagrams, connector pinouts and diagnostic procedures you can use to find where the problem is.

      My First Project and GMC has me stumped

      By davester · Posted

      can you tell if the reader is actually trying to get codes, and the pcm is reporting none, or is your reader just silently failing because it's not communicating with the pcm?

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      Any joy with this truck seems to be short-lived.   The CEL for P0172 ("bank 1" too rich) is now "intermittent".   I'm not sure where to check, or re-check, and my energy to keep chasing problems with junk is wearing thin. The P0172 seems to set as I'm coming to a stop, completely off the throttle, when fully warm. At least, that's what it's done the 3? times it's set.   Everything appears normal on the scanner EXCEPT long term fuel trim. There's only one bank on this vehicle because it's an OBD 1.5 with only one upstream O2 sensor. At idle, it's around -16.4% and will dip to -18% occasionally at idle or off-throttle. LTFT approaches 0 when throttle is held at 2500rpm. Short term appears normal, much closer to zero all the time. The LTFT tells me the engine is running rich at idle but compensating at higher load. But, why?   The EVAP purge valve doesn't appear to be leaking/sucking fuel vapor continuously. Is it sticking just as I come to a stop and the engine is choking on fuel vapor and sets the P0172? But that doesn't explain the persistently negative LTFT. Disconnecting the purge valve doesn't seem to make any difference.   I suppose that leaves another dang issue with the fuel injector. A leaking fuel pressure regulator, a new leak in the spider, or a leaking fuel injector/poppet valve I didn't see, or a small crack in one of the spider legs.   The vacuum line leading to the fuel pressure regulator doesn't have raw fuel in it. It doesn't even smell like fuel when it's pulled off, not until you suck air through it, then you can tell it leads to a fuel component. I'd consider that normal? Nothing is signaling this is a FPR issue from the outside, at least.   The oil smells like fuel but it's not building volume. I've noticed most oil in most engines smells like fuel to some degree so it's hard to say if the smell is an issue or not. Or if the engine just still smells like fuel because the crankcase was full of it a few hundred miles ago. But it's been changed twice since that original issue of the leaking fuel line dumping fuel into the intake.   Patience is running very thin. Every win seems to be accompanied by two steps backwards, or another issue that leads to removing at least the top half of the intake manifold. Enough! LOL

      Tire pressure for 37s

      By Chuck FB · Posted

      First off you mentioned "Toyo Says" and then gave the pressures 45/50, was this some person at the tire shop that pulled those numbers out of his head ?   Now of course I can't know your exact axle weights front and rear, however I have much the same pickup as yourself other than not knowing your starting weight as per the pounds the truck rolled out of the factory at due to the options yours did or didn't come with or what you have added beyond the extra tire weight. The correct way to know 100% where a person is at is by weighing each axle with the typical weight the vehicle is driven with and that means taking into account passengers and making sure you figure in a full tank of fuel and a little grace for whatever you may put in the bed "groceries" !    I am looking at and not that it really matters as all the tire companies use the same charts anyway, but I am looking at the comprehensive Toyo tire chart in the section that your tire falls under and I know it sounds confusing but your tire is not an LT metric tire like your factory tire but instead because its a standard inch measured tire its under a different category called an LT floatation series tire. That makes a difference as LT metric tires they don't want to see run below 35 psi at highway speed where as with the LT floatation series it can be run down to 25 psi on the highway as long as the weight on the said size of tire is agreeable with or less than that minimum 25 psi. It blows many people away that how is this physically possible, an empty truck for one thing and larger tires with the same size wheel diameter have a lot more air volume so they can carry the same weight as the smaller tire with less air pressure.    So my truck, I have the stock 275/65R20 wheels and tires and I have a bit of weight in the box with a bak flip cover and a rubber bed mat and some tools and spare gas. The front of my gas truck weighs a bit more than some trucks of the similar spec due to double batteries and alternators. However with full fuel and just me in the truck I am weighted such that I can run 40 front and 35 rear and so that is what I have done since day one.    If I base your truck at or slightly below the weight of my truck, in theory with your tires going by the tire chart you might be right around a minimum of 30 pounds front and 25 pounds rear. Of course that would hit pretty much minimum cold inflation pressure one could run with that tire size and a near empty truck. If you have access to an accurate weigh scale to do individual front and rear axle weights I would suggest you do that and make sure your topped up with fuel and whatever else in the truck before you weigh it and then you will have a great starting point to work off of and figure out what your bare minimum pressures are you can safely run. If you do much in the way of hot weather high speed driving, bumping up a bit for a safety margin is never a bad idea but just depends on what type of driving you do. I will include the Toyo chart and the floatation series sizes start on page 31. Without a doubt at these pressures I am speculating at minimum wise for your truck, it would most certainly ride very different then it did when you were using 55 lb front and rear.     https://www.toyotires.com/media/pxcjubjs/application_of_load_inflation_tables_20200723.pdf
