Ok I gotta ask and you may have told the forum b4 but what exhaust do you have that's driving you crazy when it shifts to V4? I have an 18" MF and although I can tell the v4 kicked it, it isn't worth me going back to stock.

I originally wanted true duals... So that's what I got. They cut all the existing exhaust right at the cat.. They installed the new pipes with no mufflers. Sounded like absolute garbage... Not like my 06.. I went to a shop down the street and picked any muffler I could finding thinking this was the quick solution.. Purchased the 40 series FM dual in dual out... It drives me absolutely insane... The v4 drone echos In the cab... It seems louder than when I'm pushing the gas In v8!!!! It's crazy

I installed the magnaflow cat back system. There is droan in v4. Not enough to make me go back to stock. In the city I drive in m5 to ensure no droan. I find the sweet spot on Highway to limit v4. Sounds great at startup and when on the gas. Deep rumble on Highway.

Exactly, I have the MF 5x11x22 muffler and while I can hear a slight burble when in V4 and under 1700rpm's it is nothing that makes your ears bleed or is annoying.

Yours doesn't echo In the cab?? Does Not allowing it to shift into 6th effect mileage at all? What about 1-5 it doesn't go into 4 cyl?

No v4 when in m1 to m5. Mileage change not noticeable. There is rumble in cab but what did u expect when installing exhaust on a eight cylinder? The cab sound isn't echo but more of a throaty sound. Classy not cheap sound.

A blackbear tune will fix the v4, unnecessary shifting, plus itll drive damn good. I dont know of anyone havin a tune that voided the warranty

Howabout checking with a shop like Midas or Meineke?

Good idea.. They should have so knowledge on the topic.. I just don't know if I should get a new muffler, get the range tool, or just deal with it... 300$ wasted so far unless I can find an option that doesn't require me removing the fm such as the range kit...

OK - I gotta ask this.

 

If a tune will leave traces that can be tracked by the dealership service department (even if you "untune" it before service), and IF a tune will create warranty issues should something go wrong, why would anyone get a tune?

 

Wouldn't it be better to at least get out of warranty (or at least a lot more certain that there isn't going to be any warranty issues)? Really trying hard to understand the issue.

 

Gotta pay to play. I had a custom Blackbear tune on my last truck (2002 Silverado) and it was a drastic improvement over stock. More power, better mileage, better throttle response. Even idled better. Truck had a 6" lift and 33" tires with aftermarket wheels and it got 17-18 mpg highway. Thats better than some people get stock with brand new trucks! I put about 30k trouble free miles on a Blackbear tune before I traded the truck.

 

But yes, there is the downfall that IF something does go wrong, they dealer will blame the tuning as a cause. Unless you can prove the tune didn't cause the problems (Magnuson-Moss Warranty Act). So if you can't prove the tune didn't cause the issue (whatever it may be), you will be stuck with the bill for the repairs.

I asked another forum member the price on a tune + autocal. He told me 600$ is it worth it?

I think when I did my Blackbear it was $600 upfront, or something like that. $300 for the tune, and $300 for the scanner deposit. You get the $300 back after you install the new tune and do a relearn with the scanner and send it back. Basically they charge the $300 extra bucks so people don't run off with their equipment. Send the people at Blackbear an email, they are helpful and will detail how they do business. Here is a link to their services. I think I did a "Scan Cable Tune." At the time I did both my Dads 2007 Suburban and my 2002 Silverado.

 

http://blackbearperformance.com/services.asp

 

*edit*

 

on that link there is a Process on what happens when you start working with them. Pretty helpful.

 

  1. You'll submit a security deposit to cover the cost of the scan

    cable hardware, amounting to either $250 or $400, depending on what type

    of vehicle you have. This deposit is fully refundable when returned in

    a timely manner.

     

  2. Using a Windows-based laptop (not provided), you'll follow

    our detailed instructions to collect one or more log files from the

    vehicle while driving.

     

  3. Those files will be sent in to us by email to be reviewed.

    If all is well, we will provide an order form to complete to purchase

    the tune. If any correction or clarification is needed, we'll provide

    direction as to what else we need to see.

     

  4. Tuned computer or computers will be mailed to you to be

    installed. Using the scan cable, you'll be able to link the new

    computer(s) to the vehicle and perform a follow-up log file. We'll

    review that log to ensure that all is operating as it should be.

     

  5. The scan cable and factory computer(s) (if desired) are returned to us for a refund of the core charge.

      on-wheel cellphone control: 2026 1500 WT (2.7L 4WD std cab)

      By bwiese · Posted

      I have a basic 2026 1500 WT  (2.7L/4WD reg cab shorttbed). Comfy, generally happy with electronics/radio - but is there a way I can add switches to steering wheel right-side position (curr. empty) so I can adjust volume, push phone button to voice dial, etc? Bill W San Jose

      Travel Trailer 2024 2500 HD 6.6 Gas Engine ?

      By Tyler Gibbs · Posted

      The curb weight on a 1 ton crew cab long bed is around 7k lbs.  Now, I don't know where you went to school but 9k is not more than 2x 7k lbs. More than 2x 7k lbs would be 14k+.   With that said, obviously yes you're going to feel a 9k lb trailer when slowing down.  I already said, when accelerating.  When changing lanes?  No.  But if you look at the context of what was quoted, the original person said, "after a mile or two..." which means that would be after the accelerating portion and you're driving a generally steady pace.  Please do learn to read and comprehend.

      Dave's Auto (custom engine builder) tear down of L8T

      Like I've said before. Di and Carbon buildup is not that big of a concern. Engine had minimal buildup, and that engine was obviously not super well maintained. Do regular oil changes, and you're gtg as long as the rest of the truck lasts. Also, the High Pressure FP that people ****** about, but can't tell you why.  Now, I wish they'd trash the variable oil pump. No real world issues with them, but I'll gladly eat whatever miniscule MPG it's saving me in favor of more oil at all RPMs.    Curious to see his assessment of the 7.3 compared to the 6.6. I expect he'll praise the port inj, but from a structural standpoint, the 6.6 is as robust as any engine out there.    Not to take away from the 7.3. I feel it's equally as good as the 6.6.     As to heat on the rear cyls, I'd have to see numerous examples before I'd say it's an issue. Especially not knowing the history of that engine. For all is known, they could have blown a rad hose, and ran it hot, and the 2 rear cyls may be the first to get hot in a low coolant situation, but not be an issue aside from that.

      "Life is getting back to normal."    I'm driving again and all new joints are operating as expected for this stage of recovery.   My most recent joint replacement still requires a lot of attention but experience has taught me that time will quiet the remaining pain.  I joked with my surgeon that another joint replacement would take my mind off my most recent surgery and he responded by saying the next will be a hip!  There are no plans for another surgery but, unlike me, I don't think he was joking!  I certainly wouldn't refuse further replacement  if required but hope to spend time out of the "post-op"  period.  I can't stress enough that if you have been recommended for total hip, knee or shoulder replacement that you welcome the offer.  Post-op "recovery" may sound daunting and painful, however, this is far better than the insidious erosion of mobility you are currently experiencing.  Imagine what it would feel like to wake up most mornings feeling better and more mobile than you did the previous day!  Prior to my first surgery in June 2025, even getting out of bed was becoming a formidable task.  Since the day after my first surgery, I get out of bed everyday easily and unassisted.  Making the switch to feeling a little better each day rather than a little worse, is hugely motivating!
