2008 Silverado

What's up with my truck holding at 90 mph and not any faster? That is some BS!

there's a governor on your truck which won't allow you to go past 90.

I know there is a governor. What I am asking is does anybody know why it isn't 100 mph anymore? Why is it 90 mph?

Probably a government thing.

15 over will still earn you a fairly pricey citation if you don't wipe out a minivan load of kids in the mean time (actually strike this last statement, I was just being unfair and over reactive).

Truth is that the Insurance Institute for Highway Safety has their hand in it, the nice thing is that it no longer feels like you lost the transmission, now it just smoothly quits accelerating.

FYI: Many cars have electronic speed limiters based on the OEM tire speed ratings, not the case here though.

Get a Programer and fix your prob.

90? I'm almost positive I had mine (07 NBS) over 110 (I have a foggy memory, but I'd put money that I've gone atleast a hundo.)

i know i have had mine at 105 and then had more ped. but gov. killed it
but when hypertech releases the upgrade im sitting here waiting for it
already got Max energy to plug it up and get what i can out of it
 

Unless you are on a official track, you have no business going 100 mph in a pick up truck.  But then again, me and my fellow firefighters call those hi speed guys job security.

Seriously guys, a pick up is not designed for high speed emergency maneuvers (example - something runs out into your lane, you have a blow out, the list goes on)  You are playing with fire and will eventually get burned.

I have seen first hand the devastating effects these decisions can have.  If you have to go fast, go to an official track.

For the record, I wasn't at an official track, but rather a buddy of mine has a private air strip, so I had a good, long, wide *empty*lane.  Didn't go back again due to him saying I needed a helmet next time (not to mention the 100 mi round trip), but if I remember correctly, with what speedy said, I think mine was probably around 107-8 somethin like that.  Then the tach went from 5500 to 3400 and stuck there.

if you "build" a silverado on chevrolet.com, there is the option of adding a 70mph governor in case some of you didn't know.

can honestly say that i havent had my 08 over 85.  usually average 80 when going to the cabin whether im pulling the boat with the wheeler in back or nothing at all.  still averaging around 17 when going 80 though so i guess it makes sense to go that fast.

i feel you there engine2
as i am vol. fire fighter in delaware station 50
track use i do alot of
so i know what i can do on the track only opened mine up once on the open road on way to a call but still just hit 94 MPH

ya i have a 07 and mine has been to around 105
 

I had an 07 NBS and have an 08 and they both cut out at 89.9 according to the GPS.
