I have had mine to 105 and then it starts to shut off. How fast have you guys had yours and if it is over 105 tell me what you did to make it not cut off

Depending on the wheels that came installed at the factory (15" steelies with ContiCrap tires or 16" aluminum with Pirelli tires) it's limited at 105 or 125.

There's nothing you can do to get past that limit since (AFAIK) there's no way to flash our ECU yet. And unless you drag race and you're hitting the limiter, you really shouldn't even try to change the limit. Going that fast on normal roads is dangerous.

what if you dealer installed the 16inch chrome rims and now i have sumitomotires

to my knowledge its 105 or 115..not 125.

My fiance's goes 115.

but the easiest way to go "faster" is to run a piggyback system.

gtxsport11

where can i get a piggyback ecu tim should i just wait untill o go turbo in a couple of months

chevysalesman614

mine goes 150+

gtxsport11

good for you once i go turbo i will smoke you ass and blow your doors off (I hope)

blkcobalt

120mph..... I also have the 16" Pirelli's from factory. Speedo was still climbing, but figured "that was fast enough!.

gtxsport11

u think that if i contact the dealer they will raise the speedo?

chevysalesman614

you do hope, cause I've got a credit card all shined up and ready for when bill hahn e-mails me about my turbo

chevysalesman614

nope, you need a tune for that i think, but i dont know who tunes 2.2s

I onetime hit 110 on a nitrous run and had this wtf? look on my face and then the next time I tried to go past 105 (no nitrous) gov. kicked in. I have no idea what happened there.

wdsoccer

been to 115. coulda gone faster but slowd down

gtxsport11

how did you go 115 when the ls cuts off at 105

AWDstylez

Amen

wdsoccer

i had the 16's from the factory. they have a higher speed rating

chevysalesman614

that makes sense. it probably cuts off on the same rpm for all ls, but i bet the bigger wheels make it a few higher mph

wdsoccer

yes sir. i can try and get a pic of if. maybe a lil video

I did somewhere around 125-128. When you're going that fast, you really dont have alot of time to look at the speedo. I know it was a little over 125, but im not sure by how much.

I'll tell yah, that **** is scary!

sick06cobalt

You guys are idiots.. The limiter is at 117 enough said... there is no way anyone went 120+ in an ls.. all of you who said that the ls cut off is 105 are idiots

Yeah, i'm a HUGEEE idiot.

YellowLT

You are very uneducated my friend. All the LS LT w/o the SPORT packaged are governed to 105 because the Crappy continentals are only rated 108 mph. The sport package comes with Pirellis and is governed to 120mph. any other questions?

sick06cobalt

^^ hmm thats funny because ive hit 115 in my car... and i have the normal ls... not the sport package and my car came with the conti's
