That is interesting. I have never heard off that. I kinda doubt it because anytime i have hit a limiter it has not been in top gear. Its restricted based on tire ratings so i don't think the gear has any role in the limiter. On a camaro that could he completely different since the tires are probably rated for more than the car will do. 

It be a while, but I think I was either in 4 gear or fifth when mine hit, and it hit hard truck was still pulling hard

That’s one hell of a 60 ft time.  My 13.08 second all wheel drive TrailblazerSS never 60 footed that good.  

I was thinking the same thing. I used to race my 06 GTO and ran a 12.42 at 114 and my 60 ft was never that good. If i could have had a 60 ft like that i would dropped a few tenths.

my calculation is 13.68, governor is 114 for this truck.

I just checked my 2018 6.2 tune with hptuners and mine is set to 135 from the factory.

I am also interested, so far 114 is the most and 102 is the least mph before computer shut it down, However,  the 2019-20 has the highest mph limiter from factory. That is of any gm production truck, Keep us posted on where your's fall in at.Thank's

Trivia:

'83 6.2s with-the-Early-Heads got similar mileage.  No governor but I suspect lower gearing - I have never taken mine over maybe 70mph, though it will go faster.  Later 6.2s of that era different heads, more power, much less economy, I've read.

If I remember correctly Detroit diesel, introduce 6.2 1982 143hp 257 tq I though it was a diesel,but guess I am wrong, either way it was down on power.

They did indeed make a 6.2, not sure who made the engine but  my son has an 85 gmc with the 6.2 diesel

I agree.

[lexoverrex]

I have '83 c20 with 6.2 diesel

'83 had early heads - fuel economy better than later - power lower.

Decent fuel mileage for 6.2 this was with down town driving with several red light's, running as fast as 75 mph with cruise control on. Also best 1/8 time with slip.

 

 

Crew cab short bed or standard bed?

 

max tow or no?
