You're right Bryan, at least I am hoping it is more enjoyable to drive home. I'll let you know how it goes. Thanks for your comment.

I am curious myself. Does Performance Tune adjust ECM and TCM?

Depends on the Vendor, some can and others are still working on it. From my research, Diablo, EFI live, HP tuners, Can adjust both ECM, TCM. I'm leaning toward Diablew to tune mine (He's a long time custom tuner that uses Diablo tuner). But have not made up my mind yet.

I already have the Efi live unit from my last BB tune on my old truck.. I'll likely go that route again. I sent Justin an email last night inquiring about whether or not GM can see the tune, if I flash to stock first. I'll post back with his reply.

Did you get an answer back?

He said they shouldn't be able to, as he modifies the factory tune, instead putting a whole new one on. It's a roll of the dice IMO.

I recently plugged in a Diablo 93 octane tune in my 2013 5.3L using the InTune device. Seems a lot better. I went with 93 tune because I primarily use E85 which has 100 octane. I will eventually get a custom tuner like Lew or Andy to work something up on the Diablo that is more specific to my vehicle. One thing I like about the Diablo programmer, Is that it has more things you can adjust than most people would want to mess with. TCM adjustments also. You could put in a 89 or 93 canned tune, and spend most of the weekend fiddling with other settings available and still not cover everything. An easy to use tuner, with a boat load of features, and very good bang for the buck. If you take the pickup to the dealer, just restore the stock tune, and then reload the Diablo tune when you get the pickup out of the shop. That is just in case they do a ECM flash update. If you don't take the Diablo tune out and "un marry" the device from the ECM, you would not be able to use the tuner and plug back in your custom stuff after the dealer gets done messing with the ECM.

I have also tuned my '13 5.3 Sierra with the Intune. I am very happy with the TCM and PCM changes. It's a whole different truck without sacrificing mileage.

Efi live hasn't released the TCM yet. Still in the works. Been waiting on them for awhile. They said it will be release this year but no ETA of exactly when. I only know that because I tune with EFI live.

My 2014 is tuned, I am actually working on the e85 side of it now. I'm hoping to get a day off this weekend so I can take it to the dyno and show real world gains between stock tune and custom. I will report back with numbers as soon as it becomes a reality.

Well, circumstances have changed somewhat. Nothing related to the Intune itself. I restored the pickup to stock tune. This was primarily because wife is the primary user of the pickup, I am out on the semi truck most of the week, and if she has an issue she needs to go to the dealership, she is not technically savvy enough to restore the stock tune. So, it was a situation that called for returning to stock.

 

Anyone want a Diablo Intune unit? Got it about 3 months ago. It is in the original box, with all cables and the Diablo window sticker. Will let it go for $275 which includes shipping to anywhere in the lower 48. Get the unit at a lower cost than new, and have Lew or someone do a custom tune for you. PM me if anyone is interested.

+1 on this. I picked up a used Diablo InTune for $210 and put the 87 octance tune on along with an Airaid Intake (MIT with K&n Drop in)... pretty noticeable difference. Transmission is alot quicker and firmer, and has smartened up alot. Truck is noticeably quicker also. HP wise, maybe 15-18hp between the two mods....But I am looking to have Lew at Diablew do a custom tune for me!

Got my first 5.3(l59) and I love it to death. I don't have any real performance shops in town so I was curious what would be the best route for getting a tune. I don't want to break the bank but I want quicker gear changes (without stress to tranny) and maybe +20flb torque. I'm totally new to custom tunes and just want something easy to understand (plug and play) thanks in advance!

      Stabilitrak conversion to Z71

      By teamjnz · Posted

      Sounds like converting will be a bigger endeavor than I was thinking. This truck doesn't have 2Hi like the Suburban did. The Tahoe has 4Hi and 4Lo and a button to turn of traction control.   From what I understand the Stabilitrak uses open diff in the front and rear. When wheel speed is not the same the stabilitrak uses the ABS system to slowdown the spinning wheel(s) to transfer power to the slower non-spinning wheel(s). I thought the transfer case was open too. Being able to transfer power either more to front or rear depending on wheel spin. Maybe I miss understood some information with you saying and power transfer is 50-50. Thanks

      OCI, not when but why?

      My brother has a 2007 Avalanche with afm 5.3. It`s got 176,000 miles. Runs like a clock. Never been apart. Co worker has a 2010 Tahoe with afm 5.3. 230,000 miles. Never been apart. Runs like a clock. So, even though cyl deac is a weak spot, they can go the distance.   BUT, these engines had the oil changed regularly, AND had 5w30 as spec. I wonder if they would have lasted this far on 0w20? I`ll bet not.

      I certainly could be wrong but I hear of pickups far newer than that 2007 cutoff which may not be going to the wrecker but are having engine work done and be that a reman engine or new engine or trying to repair the existing engine. Some of it would be design issues as per the cylinder deactivation system that GM has and one of those lifters wiping out the cam and the question of oil changes moving the needle or not on that whole mess, or in the case of Ford pickup engines that have the long timing chains and wearing them out and the roller followers and phasers and some of that certainly goes back to oil change intervals. But in those various cases the truck has all sorts of life left in it and so the unfortunate owner and may be original owner or used market owner that is pouring money into repairs so the truck is not seeing the salvage yard yet but damage is happening by infrequent oil changes. A friends son had bought a 2018 I think it is half ton GM and it had some sort of extended or used dealer warranty on it and of course the lifter issue bites and its rattling and so the dealer had to swallow the bill and was at least 7000.00 and I think they only replaced what they felt they had to replace so yeah, I can see that being a ticking time bomb in the not too distant future. Would frequent oil changes cure all these engineering "marvels", probably not but some engine designs have shown that they do much better if the oil is changed a lot more often then if the manufacturer service claims are followed. New trucks cost so much that there is an incentive to keep the existing truck on the road by repairing.

      Tranmission stays in Low

      get a good code reader, and find out what problems the truck has noticed by reading codes. cheap ones can only get basic engine codes, you may want to get one that can get codes from all the computers in your truck.

      This is sort of my point, salvage yards aren't overflowing with all these 'poorly' maintained trucks - excellent/good/servicable condition otherwise, salvaged only as a result of a bad engine from poor oil change regiment.    In my area, there are no 2007 to newer gm trucks/suvs in any salvage yards. A few are in the 'recyclers' with very obvious reasons for being there - wrecked.
