I assume that you must have increased the shift rpms because the normal tune for the transmission at least, does not have any shift going above 5600 rpm. The 4 to 5 shift and the 5 to 6 shift are both set at 5200 rpm. That's default for the firm and hard shift tune in the TCM.

The hyperteck tune lets you raise the RPMs and shift points by 500, turn off the AFM and turn off the TM if you wish. There are more adjustments as well, and that just a hand held tune. I just turned off the AFM, raised shift points, and top speed. Their engine tune only gave you 7 HP on 93 grade gas, I run E85 95 percent of the time anyway so left it at stock tune. My truck runs great.

Yep, can do the same in Diablo sport. I was really close to going with the same hypertech that you got. Went Diablo only due to the supposed ability to hid it from the dealer (tested by jaws52).

I got my diablo intune the other day and was frustrated when it couldn't read my PCM, but after emailing support they were able to fix that. However, I installed the tune and it doesn't give me any adjustable parameters at all. After it installs the ECM tune the Intune just reboots. I emailed Diablo and they said thats normal. I'm kind of pissed about that as the main reason I bought it was for the throttle booster and AFM disable.

 

Anyone else with a 6.2 able to adjust parameters other then just load a tune?

 

BTW drove the truck and it felt exactly the same after the tune..

When I installed the 93 tune and it rebooted I went into tuning and adjustable perameters and it gave me the options you are looking for. I raised the throttle response by 10% if I remember and turned off AFM. When I put it back to stock to bring it to the dealer I noticed a big difference, really realized how much just a canned tune helps these trucks. After I had the latest updates done at the dealer it doesn't recognize my truck anymore. I emailed them my pcm file copy and am now waiting for a response.

Wonder why that is? Seems if you set it back to stock, then dealer updates, when you go through the process again, I would have thought it would be as if you were installing for the first time. Apparently not.

That was my issue initially. My truck had the update done already. I've tried again and it still won't let me adjust any parameters, just install the "Diablo Tune." Not happy about it.

I bought mine before the claim was made by Diablo, I've used them before on my trailblazer ss and was pleased with them.

I'm sure this has been covered before but I'm lazy to read through all 42 pages lol!!

 

Question for anyone that has put a wideband on their stock 5.3, what AFR are you getting stock?

 

I was looking on AFE's website at their provided dyno graph and it's showing a mid-high 14 AFR in stock form, I thought that seemed really lean for stock

I'm not exactly sure what you are taking about in regards to wideband lol but maybe this screenshot will help. I'm Diablo tuned so maybe a little different stock but AFR always seems to read 9.76:1 at idle or any other rpm/speed.

A wide band shows you the exact AFR, its a sensor that plugs into your exhaust.

 

Not sure how much I trust that reading of 9.76, seems crazy rich!

Any luck? Diablosport has left me just waiting..

Stoich is 14.7 and your target value, i.e. ideal fuel/air ratio. How do you get that it's really lean?

 

I can't imagine why anyone would put a wideband on a totally stock truck. Adding a wideband allows for precise custom tuning and there's little point in that without mods.

I'm not talking about stoich, I'm talking wot afr.. And anyone who is tuning I'm sure took a baseline afr reading, that's what I'm asking for. I know what the truck needs to run but curious to know what it's running stock.

    • Well that book won't sell many copies. Taking ones right foot off the loud pedal never gets applause. Funny really, It isn't that people don't know what to do...they just don't want to do it. But they will complain about it. About bad craftsmanship, about the cost of fuel, about the cost of part and repairs and mainly they complain that the solution while still possible isn't one they are willing to do.    I observe this daily. 'Gas cost to much!", they wail, while they mat it passing at 80+ mpg and scoot down the road like gas cost a dime a gallon. Then complain about the few that will lift and save both fuel and iron like they are owed and own the road.    Good thing they haven't an ounce of influence on my equipment. The rest I just laugh at. Stupid is as stupid does, right Forest?     
    • Today I filled up with 4.899 gallons of fuel at a cost of $4.899 a gallon. $24 bucks. 290 miles. 59.2 mpg. After my 4% COSTCO discount just under eight cents a mile.  
    • Howdy folks,   Recently I pulled a heated steering wheel and clock spring out of a 2015 Sierra All Terrain (part numbers coming soon - will have to disassemble), and just installed it on my 2016 Sierra WT (as base model as it gets).   On install, I noticed that I’m missing the connector often tucked behind the dash for the heating element.     No problem… or so I thought.   I used an “Add-A-Fuse” at my heated steering wheel fuse location, which has voltage, but no wires. I ran it to the positive of the heated steering wheel (Violet/White), and took black to ground.   Hooked up the battery, turned the truck on - no heated steering wheel. No button backlights. Was pleased to see that my cruise control was working though.   Read a post suggesting reversing polarity, so I gave it a shot. Violet and White to ground, Black to power.    Aha! Heat! But I seemingly can’t turn it off AND still no backlights on any of the buttons.    Checked all fuses, everything is still in good order. I’m stumped.   Does anyone have any insight? If so, please share!
    • I'm about 1800 miles into my last oil change, and yesterday a message appeared saying oil life was at 77%. Not sure why it popped up but I think all of these electronics could be susceptible to solar flares or somesuch. I change my oil right at 3K each time, and that was the first time in 10870 miles that message came up. Strange thing is that it showed on the screen at all since I don't drive with that sort of info displayed on the DIC.
