:cheers: Hello gang. First off, today is Sept 11th. Take a moment to reflect on the past and what our military is doing.

 

Ok...

 

I purchased a tune from Jesse and have since drivin just a tad over 1000 miles with it.

 

What I got: 87 mileage tune with the torque management taken off and a firmer shifting option.

 

PROS: ummmmm. truck seemed to pull better and stronger above 4000 rpm. But I seldom go that high.

 

CONS: Mileage went down, not up. My driving habits didnt change. I didnt change gas stations. Only use Mobil 1 gas. I drive at 65 out on the turnpike and work is 52 miles all one way. I dropped from an average of 19.7 mpg to 18.1. With today's gas prices, I think this is a significant drop.

 

CONS: My 4x4 indicator on the dash (I have the manual transfer case) did not illuminate when the truck was in 4 Hi or 4 Lo. I am not sure why an upgraded PCM would do this.

 

CONS: My shifting firmness was the same. Still had a lag from first to second gear changes and the tranny shifted (what i would call, lazily).

 

Other little things that I noticed, neither good nor bad....The oil life monitor had to be reset when I hooked up the new PCM.

 

I dont know, maybe my truck already had some sort of tune done to it (bought it used last April, have since already put on 11K miles on it) and the tune that I got from Jesse was the same or similar tune that may have been done to it already.

 

Maybe I got a bogus tune? I dont think so, not from reading what others have praised about from his tunes.

 

I just thought I would let everyone know. Is always great to hear good news from a custom tune, unfortunately for me, mine wasnt that good.

 

Take care all.

The oil life monitor info is contained in the PCM. I had the same thing with mine.

 

I don't think the 4x4 selector info would be affected. Mine had a bad switch in the dash, causing the same problem as yours. Maybe it coincidentally went out at the same time? Unlikely, but possible. EDIT: Doh! I reread that you have a manual T-Case. Disregard last transmission please...

 

For the MPGs, did you verify it was still logging the same miles? When I had a pcm4less tune, it was tacking on a couple extra miles which made the mpg look better. I really haven't noticed any change since switching back to my old PCM, other than some oddities disappearing, like fake increased MPG, Indicated Miles, Speedometer Error, and Hesistation.

 

I've been thinking about going for a Jesse tune, but I'm waiting to see others post outstanding results before I get one. I don't think pcm4less gained me anything.

The 03-05 Vortec 4800/5300 engines are tuned almost as much as possible from the factory. The Vortec 4800 always pulled like a mad animal above 4,500 RPM whereas the stroked 5300 found that power near 3800 RPM.

 

If you still have a lazy 1-2 Upshift, maybe Jesse left some Transmission TM in and removed only 100% Engine TM and Abuse Mode. However the ratio change from 3.06:1 to 1.63:1 is pretty drastic and it may feel lazy.

 

I know Custom Tuners are tuning for an Air/Fuel Ratio of 12.9:1. They claim the added fuel really wakes up the Vortec engines, but it also brings up power to a level that actually increases economy. I am gonna do more testing on my truck to see if this is accurate. I assume this is why you lost economy.

Contact Jesse, ask for another burn.

 

There are so many variables at work with our trucks, the tunes, fuels, etc., that every so often, even the best tuners need a shot or two to get a particular tune perfect.

 

I've heard nothing but positive about Jesse and his tunes (with one or two stories like your thrown in). I'm certain he'd be happy to give it another try.

 

 

 

Hey, gang, just a little mini-rant here:

 

When you get a tune, or ANY aftermarket item, for your truck, and results aren't 100% what you excepted, contact the vendor FIRST, before going public with the problem. Most of the times, the vendor will be stand-up and want to take care of the problem. Going public can often cause a potential customer to have second thoughts when there very well could be a very simple reason and fix for what's going on.

 

This site is an awesome source of info, but sometimes it's better to just keep it quiet and deal with your vendor directly first. Then you can post how you had a problem, contacted the vendor who in turn JUMPED on the problem, and the customer service was phenomenal !!!!

 

Ain't that better :cheers: ?!!!?

 

Good luck, 96. Let us know how it goes.

Jesse does a great job, when I had a concern about mine, he fixed it right away. So much so, that I got another tune (of which I do not use because of the price of gas). I am thinking about getting a tune for my wife's Monte, and also getting one for the new truck that I am looking at right now. I have refered a lot of people to Jesse that have all been happy with the results.

I've had my wait4me tune in for almost 2 months now with no issues :dupe:

 

I had him remove torque mgt and get the most out of my engine as he thought he could.

 

Overall, MPG is up an average of 1-2 between highway and city driving.

 

I agree with the above, if you have ANY issues, contact Jesse. He is more than helpful on the phone :mad:

Mr Quadrasteer has a great point. Thanks bud. Ill have my Wait4me tune nest week, ordering it tomorrow. :cheers: Im getting Jesse to do the mid-burn. Take out the torque management, burn it for 89-91 fuel, and map for gas mileage in my 8.1L. I have had a hard time deciding between Jesse and Westers, but I will definatley let ya'll know when I get it.

 

 

Rock on.

Mine light doesn't work either,I was going to put the old PCM in and see if it works then.I'm sure if you send the PCM back to Jesse he will make it right!

      OCI, not when but why?

      By Chuck FB · Posted

      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.

      By asilverblazer · Posted

      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.

      Stabilitrak conversion to Z71

      By asilverblazer · Posted

      Stabilitrack was a stability control, traction control system, that functioned independently from the transfer case.   Z-71 has nothing to do with the transfer case or differential.   If it does have an AWD system, my memory recalls this being specific to the Denali trim, converting won't be as simple as swapping out mechanical parts like differentials and transfer cases. It will require reprogramming at a minimum. Long story short, not likely worth it.   Pulling a fuse, may disable the AWD system, it might also prevent any other transfer case functions.   However, the AWD case was generally based on the same transfer case you refer to in the 2006 Suburban. If it still has a 4-High and 4-Low where the transfer case locks and splits power 50-50 front to rear, what are you gaining by changing anything? A true-rear wheel drive only, what good will that serve? Not enough to go through the trouble of changing out all the parts.    Generally, all the factory systems will handle a 33" tire and re-gearing. Probably a 35" tire too, if you aren't driving like a caveman. If 35" tires are in the plan...   If you do plan on driving like a caveman or are fully committed to 35" tires, an entire re-think of the build is probably in order. Starting with square one, an IFS front end isn't going to be the best starting point for 35's and caveman driving.

      Oil Consumption

      By PunchT37 · Posted

      1/2 qt over full ain`t gonna hurt $h!t. Most times, a whole qt won`t either. Most have windage trays now. As long as the crank isn`t slapping itself in the oil, it`s not the end of the world.   We used to overfill 1 qt at the track, at race time. Better to have it over full than having the pan sucked dry at 6500 rpm`s.
