Stock?

VERY nice!!! Surprised the speed limiter didn't kick in.  I thought they were only good to 98 or so.

Depends on the speed rating of the tires. Some limiters are set a little higher it seems.

 

The older trucks were 98mph pretty much no matter what.

My wife's 2019 GMC Sierra SLT CC 4x4 with the X31 package ran a 13.87 @ 103.31 at Mokan Dragway Yesterday.

Wasn’t your ‘15 quicker even shutting off at 98mph before the finish?

Yes, my 15 shut off at 98. This new truck the limiter must be higher because it didn't shut off before the end of the quarter. Maybe because of the 10 speed. The DA when I ran 13.73 in the 15 was less than 200 ft. the DA on the 19 was over 1600 ft.

That's quite the diff in atmosphere, but I would have thought the new style almost 500lb lighter trucks would be a bit quicker.

I was hoping it would be too. I haven't weighed the new truck yet, but the 2015 weighed 5735 lbs. at Gateway dragstrip during Dragweek with the spare tire removed and 1/4 tank of gas. Of course I added twin turbos with an intercooler, a topper and bed rug. The new truck had a half tank of gas with the spare tire removed. I was in the truck when it was weighed also. I weigh around 180. If I can find some scales I will weigh the new truck to see what the difference really is.

I've not had my truck to the track yet, but using a Dashawk my truck ran 13.8? at 101 with about a full tank of gas.  I know not the most accurate but I at least have an idea.  That's with 1" taller tires and the speedo not corrected, so actually it's a little bit more that a 1/4.

Can you tell much difference with the tune?

No, not really.  It's only an engine tune for whatever advertised gain. No tune for transmission.   The main reason I got the tuner was for eliminating the top speed governor.  I think a good transmission tune would really wake this thing up.   I have not sent anything to Lew the Diablo tuner guy for any better engine tuning yet either, but the trans can not be tuned by him yet either.  A place about an hour away can tune the trans but it's about $1300, not really worth it to me at this point.

I know it's a long way to drive, but Advanced Modern Performance just outside Dallas tuned my engine and transmission for $750 and did an outstanding job. After I put the turbos on I took it to a place in Kansas City and had it tuned. It ran like crap shifted weird and kept throwing engine codes. I took it back but it wasn't any better. I guess you get what you pay for. That's why I took it to AMP. Didn't have to go back and runs and shifts great.

I think the place by me will do a good job.   Unfortunately the ‘17-‘18s are more expensive to tune.

Look up CAT Scales and put in your zip code.  Most truck stops have them, $10 for two weighs.

Weighed the wife's new truck today on Cat scales with 3/8 tank gas and me in it. Weighed 5600 lbs. and cost $12. I can't see that much difference in weight between the 2019 and 2015 if you compare apples to apples.

      Injector update

      By iso221 · Posted

      Because single shot injectors are ancient and multi hole injectors provide smoother running engines and sharper throttle response due to the fuel being atomized better..the best lead I have is a 24lb blue top injector almost everything matches up but the injector will put out about 26lb/hr which is just outside the gm threshold.figured id ask here to see if there was an absolute answer

      Injector update

      By CamGTP · Posted

      Why is my question?   Any change in injectors requires a tune. Unless you are going back with the OEM part number or a newer part number of that same injector.   Any size difference or type difference like the EV6 style injectors all have different injector data for them. And there is no EV6 injector that matches the factory 25 lb/hr size that your truck comes with. I've been messing with these trucks and tuning them for a long time and what you trying to do doesn't exactly make sense to me.

      When a condition becomes a business model.    https://www.gm-trucks.com/gm-truck-suv-incentives-pricing-2026/   Zane posted this in "Latest Articles".    The honest bottom line   Truck buyers have spent three years assuming this is a temporary condition that will break once inventories normalize. GM just presented it to investors as a durable strategy, on a chart, as evidence of good management.   Inventory did normalize. GM is at 511,000 units and squarely inside its own 50 to 60 day target. The discounts still did not come back, because the low incentive number is the goal rather than a symptom of shortage.   Plan your purchase around that reality instead of waiting for it to change. Follow our ongoing GM News coverage for pricing and incentive changes as the next-generation trucks land.

      Winter Returned

      Thought it was raining this morning when we woke. Nope. Dew point was over 80 F and humidity 98%. Zero visibility distance. Everything was 'sweating'. I've seen rain come out of clouds but never out of Pepper or the tree trunks.    Wicked storms just missed us sliding off to the east but by blocks. Heat index about 110 F with air temp in the 90's.    This is  our third wave this month of multiple days of this type of weather. And yet the grass is going dormant and the ground is cracking this side of the street and water up the the hood opposite. Just weird stuff going on.
