Nope,I've had three of them,One for my '99,my '04,and my '07.

The only issue with the one for my '07 is that it disabled the AFM,so I sent it back to them and they sent me a "Max-Energy" at no charge.

Stang233,

 

I have researched this far too much and found one post on another GM forum of a guy who had some pinging issues with a HT unit that he could not correct. The post was a few years old and the only one I found with an issue out of literally hundreds of posts concerning Hypertech.

 

From what I have found, it is the safest of any of the Hand Held units but also the most conservative. Superchip's flashpaq would be next in line as far as being safe but it will produce more power from what I have read. Diablo is next but there are a good many posts about issues with it. I think it is a great Hand Held and will produce the biggest increases but it takes a little more work to use it. There are some members here that love them.

 

It would also seem the Hypertech will produce larger HP and TQ #s down in the low to mid RPM range but the others catch up in the mid to upper range and then surpass it in the higher revs.

 

I will also add that if you contact Hypertech either by tel or via website, they will treat you like a Customer and will take the time to answer your questions. I cannot make that comment about the others and I will leave it at that.

Thank you so much for that reply. I really appreciate your input. I think i will go ahead and tune it for the 87 octane. They are saying 28hp. That is pretty good. And if you are seeing it down low that is even better. Thanks again, Richard

Hypertech programmers give you 28 hp in your mind when you program it and when you drive it and you think its faster. They actually might give you 2.8 at the most. Now if you had a diesel thats a different story

Jeff, are you saying your Max Energy is really not effective? I know they will not make a huge difference but I have read pretty good comments for the most part. Also, their dyno sheets show the numbers to be pretty good down low.

 

I just wondered what your experience had been and are you running the 87 or 93 tune?

I was running the 93 tune. I noticed NO difference at all from low to 3000 rpms. Ran the same. Once I matted it to the floor it felt a little better and faster.

 

All in all, I wouldnt waste your money. I wanted it to change shift points, rev limiter, speed limiter, and recaibrate my speedometer. I bought it for 50 from a kid at my school that hated it, and I hated it too, so I sold it for 300.03 cents on ebay lol. Also its supposed to make your MPG a little better, and it shot it into the ground. I was getting 11.6 before the Hypertech. After with 3 tanks average, I was getting 9.8-10.2. Id save your money.

Your only getting 11.6 MPG?!? :fume::thumbs: ...You got a problem somewhere,I never got less than 15 with my '99.

Also all the Hypertechs I've had (Six of them) never affected MPG,Either up or down.

Na,Don't really drive like that :thumbs:

Still though...11.6 seems kinda low even for that kind of driving.

      2020 Trailboss 6.2 replacement

      Correct.  2019-2021 model years are serviced by a different p/n.  19420611.  Recall 2021s use 19420611.   The recall engines 2022-2024 model years are serviced with 12740076.     The difference between 19420611 and 12740076 is GM changed injector size for 2022.  The injectors are smaller on 12740076 with smaller injector bores in the cylinder heads to match the smaller injectors.  So you can't install a 19420611 in a 2022-2024, and you can't install a 12740076 in a 2019-2021.     Both engines are the replacement engine p/ns that are in the L87 recall.  So both of these are the updated engines.     Here's a version of the L87 recall with the p/ns for all the parts needed.    RCRIT-25V274-7075.pdf   Note it shows 19420611 and 12740076 with an asterisk to a footnote "Use the VIN and the GM Electronic Parts Catalog (EPC) to determine which part to order if two or more part numbers are listed for the same part, as it may vary by vehicle options."

      Looking for advice from this group. Took my flawless 2020 6.2 TB to an unnamed shop for routine rear brakes and oil change. Tech forgot to put oil back in after the full service and needles to say, destroyed my engine.  It’s all on their shop video so they are responsible.   I had my Chevy dealer do the analysis and they confirmed its compromised and said engine replacement. The manager said they only get GM reman engines from GM with full 3 yr warranty and the one they would put in is not same as what’s they are swapping out on 21-25 for recall.    I am looking for advice why that would be a different engine because obviously I had the good 6.2 year and replacing it has my concerns with that recall for 21-15   Also what’s the pros and cons of accepting the engine swap vs telling the shop that bricked the truck to pay up so I buy a new truck. I’m concerned about stigma resale eventually if I just decide to get rid of it after the swap or other issues showing up after the swap out.

      AFM Disabler Question

      By GN2018 · Posted

      Just looked up my records.  I've never gone over 5000 miles between oil changes.  At 46K miles, I have 10 oil changes.  I hope that will help.  I also installed the disabler last year.  I've still had a few times when it didn't seem to engage (which I can tell because the start stop feature kicks in), but for the most part, I think it's working.  For some reason, GM did not include the number of cylinders running in the information screen like I had on other models.  In my Cadillac, it shows me when it's running on 4 cylinders on the fuel milage screen.  I can't find that on my '21 Denali.

      AFM Disabler Question

      By Grumpy Bear · Posted

      Melling I believe is/was the OEM on the lifters who explored this problem some years ago. The white paper they generated on the topic indicated two items of note when I read it. 1.) They only fail on the switch. Prevent the switch, prevent the failure. 2.) The majority fail due to deposits messing up the timing of that switch. Anyway that's what I got from it.    Mine have always been active, 195K+ now, and my oil maintenance is surgically clean.    Of course this assumes good parts. That is no heat treat issue or machining flaws. I get comfortable that these issues are in the rearview mirror by about 30K. IMHO naturally.
