I have a 2021 6.2L TrailBoss and I have added a 3.0L Whipple Supercharger and ECU unlocked by HP Tuners. All the work and dyno tuning has been done by National Speed Inc. They have been able to squeez

What I don't understand is why everyone is upset at the cost to tune their vehicle.  Something that will last as long as you want, but think nothing about throwing $3 to 4k on wheels and tires. Then a

I think we have a language barrier.  I’m saying gradually adding hp or torque is easier on the drivetrain, and you tell me I’m wrong and then say the same thing.  I think.

Trifecta has a tune that is around $700 for 6.2L. Does anyone have any information on this other than tech from the company that says significant gains?

Yes, they do but it's for the K2XX body style trucks. There is nothing on their site that I found for the T1XX trucks with the 5.3/6.2 engines.

My 2018 Sierra SLT with 6.2L had a Hypertech tune and it was rated at 27HP/23TQ. I purchased it for $300 through Autoanything, and it was quite impressive for a plug and play system. Their staff is super knowledgeable and easy to work with. They basically tune the truck to it's full potential, then cut back 20% for safety purposes, is what the tech told me. I also had cat-back exhaust and S & B CAI on it. 

I was leaning towards BlackBear, but from what I read, even they couldn't re-tune the tranny at that time, and their gains were not much more than Hypertech. So I saved over $300, and I chose them mainly because of AFM and speedo re-calibration. It exceeded my expectations, and for the price it was unbeatable in my opinion. 

Wish GM wouldn't have made their new trucks so hard to tune. Most of us just want a simple bump in HP/TQ, along with adjustments of the speedo.

The wait is over! Diablo just released THE PULSAR LT CONTROL MODULE - 22451 https://www.diablosport.com/shop/pulsar-lt-control-module.html?SID=oidk3q1ekdcrjjam9c51mnukd4 Adjust speed limiter, tire size, throttle response, tire pressure, gear ratio, DFM disable, Auto Start/Stop Disable

This still doesn’t give you anymore HP/TQ does it?  
I’m hoping now with this that HP tuners will lower their price and we can tune our trucks for around $800 to $1000.

No it doesn't add any HP or TQ but it does what I was looking for. Adjust the top speed limiter, auto stop/start, throttle sensitivity, and DFM disable. I'm not going to pay 1,300+ programing just to get 30-40hp. I've already put the GM cold air intake and performance exhaust on it and I think with the throttle sensitivity it'll be a huge gain. I would have to put a supercharger on it to justify spending that much on a program.

I’d pay $1300 for 40hp. Heck my exhaust and CAI was $1650. Might have gotten 20hp out of it.  If you can get 40hp for $1300. That’s a bargain if you think about.

White Audio Media group (WAM) can do all this and it's 300+60 for the tool rental.  It can also do a ton more like auto-up windows from keyfob

The throttle sensitivity is like adding HP. It responds so much faster that it will smoke a truck with more HP but no the sensitivity adjusted. The stock adjustment is just sluggish.

I totally agree, but if HP tuners lowers there price, and you get all that you have with the pulsar and pay another $800ish for 40hp. That’s what I’m looking for. 
 

I’ll wait till this spring to see if anything else develops and some more kinks get worked out do this pulsar unit. From what I’m reading it’s sounds very nice.

I like the Diablo because there is no flash needed. once unplugged there is no trace it was there unless the GM tech guy pulls your speed history.

Also I would be leary because HP tuners are the only ones so far who have broken the code.

They are the only ones to break the ECM.  Crazy enough, it's a 30 dollar chip but a ton of work to get that thing open without trashing it.

 

BCM is a different piece of the puzzle and that is what WAMs adjusts.  Owner is on this page but forget his handle.  Anyone know it?

It will only smoke that truck if your both racing at part throttle.  I’ve personally never tried that.  It doesn’t add any wot horsepower, it just tricks you into thinking you have more.

      J&L OIL SEPARATOR CO

      By Grumpy Bear · Posted

      Just did an injector/HPFP replacement on Pepper at 192,400 miles; close enough to 200K, RIGHT? (If 200K is considered life end and to me it isn't). But hey, to each his own.    Have never run a catch can on this vehicle. Back side of every valve looked like a new valve spray painted semigloss black. Port walls looked 'neat' (all a normal result of passive EGR via VVT) Zero build up even in AFM cylinders. Just color. It uses no measurable oil and never has.    At 155,000 I put her on E-85 and a borescope of the cylinders at plug change showed very clean pistons and valve faces. The replaced injector tips looked new. (It was the pump piston seal that was leaking). Oh well, have six good backups.    Still gets 28 mpg on gas (highway average) and over 20 (highway) on alky. UOA's look good and runs as good now as it did when I bought it. Better in fact.    What improvement would a Catch Can provide this motor?     And given all this I expect that IF I installed one I'd see some water/gas/oil vapor accumulation. Byproducts of normal combustion.   Having said that, IF my motor used an appreciable amount of oil I'd consider it a useful 'crutch' until I had the situation corrected OR if bore polished, until I junked it or rebuilt it to stave off repeated plug fouling.    I'm not telling you what I THINK. But what its DONE.

      Starting a new thread regarding mounting my 2014 OEM wheels to my 2026

      By Grumpy Bear · Posted

      Love the look. I'm a SCSB lover myself.    Two items. 1.) A spacer changes scrub radius but this also changes when we use wheels of different offsets. A little isn't a big deal. 2.) Steel wheels, alloy wheels all have different thickness. Same effect on the stud and lug nut as a spacer. When hub centric the wheel isn't supported by the stud. It's supported by the hub. The stud just keeps it all together.

      2016 Sierra 5.3L L83 new injectors now runs rich.

      By JAI3 · Posted

      I had a evap sol go bad a couple weeks ago. . I replaced it.  While watching live data at the time I saw I had some cylinder 1 misfires. No MIL but on live data I could see ~50 at startup and about 70 more after an hour a drive all on cyl 1.  I also noticed that the LTFT were -5% to -15% always.  And that bank 2 is always -3% richer than bank 1. Even across all driving modes, city, highway, etc it’s always 3% richer than bank 1. So I start with the misfire. Swapped coil, plug, and plug wires from 1 to 3. No follow. I got an Injector reseal kit, pulled the D/s injector rail, swapped #1 and #3 injectors, resealed them, reinstalled and retested.  The misfire followed to 3. So I ordered and replaced all 8 injectors, spark plugs, and plug wires. Also replaced the 1 time use fuel pipes under the intake manifold.  Injectors that were in the truck since new were  Part # 12668390.  I replaced them with # 12742701 Got from RockAuto. Pretty certain they’re genuine and the correct ones. I called a friend at a parts store who told me “the 12742701 were the correct superseded part # for the originals I was replacing”. So started truck after replacing all that and it’s running -15 - -30 LTFTs. I reset the fuel trims with GDS2 and drove it for a 60 miles trip each way. There have been no changes in the LTFTs.  I checked if the HPFP was leaking into the crankcase. I removed the pvc and watched the trims. No difference.  I checked the alcohol content and it was at 10%  I’m out of ideas here. Truck seems to run great. Just always rich on the fuel trims.  Anyone with any help or ideas would be greatly appreciated.  I ran an injector balance test just for the heck of it and it came back this. I’m confused.  I have gds2 and some other diag tools if anyone knows of anything I should test next.
