does a stock LLY truck smoke?
 
the reason i ask is cuz my brother has one and before he had any mods on it, it smoked when he got into it. Also its very touchy. The difference between barely gettin on it and really gettin on it seems like a toe twitch. Just wondering if they're all that way?

Also do they make a mild tune that doesn't wipe out the govenor?

when mine was stock it would puff a little bit of smoke on a warm day but nothing noticable. it should smoke very little if anything when stock.

you can make a tune pretty much any way you want it now days. :tu:

Well i want to know if his maybe has one of these mild jobbers. His smokes not like my 12v but more then stock.

that dont sound stock. they are pretty clean stock, even some tuned ones are pretty clean.

and the touchy throttle your talking about dont seem right :humm:

justinb12 04-07-2010 09:44 PM

its also pretty quick. he'd get me (cuz i shift and his Allison does it for em) all the way i think.

My 04.5 lly never smoked stock (let alone with a tune) and no touchy thotle sounds to me like someone traded it in with a programmer sill loaded :nose:

If it was traded in with a tune go to dealership and have them flash the computer

My 04.5 LLY before I changed to straight pipe exhaust would puff a little black smoke when I would stick it to the wood. I know this because I tried getting out of a ticket for playing in the rain, the cop said very politely quit bullshitting me... I saw the black smoke.

Once I changed the exhaust, the black smoke became very noticable all over my bed and RR wheel. I have no tuner on it, side exit exhaust and it was bone stock. So yeah, I do believe its a common thing to show a little black smoke in stock form!

When towing heavy taking off from a standstill I've seen them puff a lot more, but not black though, never black, just a hazy cloud.

Old thread! When I first got mine it smoked pretty good for a stocker and my throttle was night and day compared to the bl's lb7. I got a heavier spring on the throttle now but before just the weight of my foot would drop it to wot lol:tu:

mine when stock smokes but i have manual 6 spped.. not dark but decent

cstlb7 12-14-2010 10:39 AM

your a lucky s.o.b to have a six speed manual wish i could have got one in my lly:argh: and i dont think they really do smoke my girl drives the lly its all stock other than a custom autozone exhaust tip she put on there once again:argh: but i will drive it and get on it hard and even try to lag it on the highway and i never get anything worth talking about honest

never had much smoke out of my lbz... a small puff when i layed into it hard, but nothing spectacular, even with a 360rwhp tune it hardly smokes:hellox:

My dads gotta 2006 One ton thats bone stock and if you putter around for about a day and then put it to the wood from a stand still it leaves a pretty good sized cloud you can't see through!! :tu:

thats not right, mine never smoked that much... ever, the only way i could smoke that much is if i tuned it that way, not going to happen stock, period.

could have a tune still loaded, or a under the hood tuner still hooked up, or the could have upgraded the fuel pump.

After I took my 04lly muddin which is hard on any truck it smoked pretty good it was like I broke it in or something either that or I broke it.:tu:
