As long as the tuner knows what he/she is doing it will be fine.

Has more to do with how you drive :yes:

 

Depends on who does it really, I mean we bought two trucks just to test and did months of testing on numerous beta trucks including our own prior to release.. It's all about testing ESPECIALLY on the AWD

 

tunes will kill ur ride leave it stock!!!! naw jp it wont hurt if ya got someone to do the work right!!

 

chris, what is the wating time for a tune and cai out of curiousity.

thanks
Ralph

btw, I am planning to remove my resonator, should this be told when I order tune?

 

Tune no wait, CAI is going to be another week before we start accepting orders again. We wont take any more orders until the list is filled and we have at least a few in stock.

 

IMO, there are two factors that will hurt your drive train. First is the total removal of torque management. All it is, is simply the engine pulling timing when it shifts. You can actually adjust how much tq mgt you want removed so that you get firmer shifts, but it won't kill the transmission. Second, is the transmission from launching. If you have a higher hp engine and you launch without breaking the tires lose, it's hard on the transmission and if you have a clutch, it's REALLY hard on a clutch. A few launches won't hurt, but do it alot, especially in the AWD, and you will find your tranny broke.

 

As much as I respect the people that offer tunes, I would never do one on my vehicles. I'm concerned that tunes will wear out the parts faster than OEM. I'm hoping the big companies didn't pay their engineers for nothing. Their main concerns are reliability and durability. You can always make things better in one way but have to give something else in the long run.

I also do a lot of traveling with my cars so I prefer to keep everything OEM so I don't have problems with the manufacturer on claims. I have a lot of better things to do then waste my time with a dealer arguing if my aftermarket part is the problem.

This is just my opinion due to my driving preferences.

 

jsu ta tune dealers will not notice a thing^^^^^^

Thats why you bought an Envoy and I bought an SS.

If a tune is done right, you'll only benefit from it. Your driving style can effect the durability of parts as someone already said. More stress equals more things that will break. If you get serious with the horsepower then obviously your parts won't last as long but a tune is not enough to surpass what the drivetrain can handle. But as always, you have to pay to play

 

you dont have to worry about tune's, you hav to worry about the driver. NO detonation, NO long stalls at the track, change oil and filter at 1000 then 3000-3500 after that, change trans fluid and filter at 25k. dont push truck hard when it is still warming up. simple

Reduced engine and drivetrain life

Most people don't want to hear it but more acceleration requires more torque which loads parts more heavily and reduces their life. An aggressive shift that snaps your neck back is the equivalent of a kick in the balls to your transmission. Time will tell.

If you don't floor the throttle when you drive you don't need a tune - just press the gas pedal to go quicker.:yes:

 

Mod the hell out of it. If it breaks go buy a new one. I'm lucky to keep a vehicle for more then 18 months so reliability don't concern me too much unless stuff is breaking at 5000k.

 

There is another school of thought....a tune equals a more complete burn of fuel in the cylinder. This reduces deposits, lowers emissions, improves power and extends the life of internal engine components. If you drive like an arse hole you are going to wear things out no matter how your car is tuned.

Fiction.....no doubt about it.

A tune is basically worthless unless you drive quicker than you could stock. So you're gonna break stuff sooner, especially with hard shifts that do nothing good, especially when accelerating out of a curve.

 

Drive the heck out of it and buy an extended warranty!!

I bought a Denali because I was tired of driving my CTS V in stop and go traffic. Besides it had a bad enough time staying together and it was stock.


I think the person that open this thread asked if a tune will affect the longevity of the engine and transmission. Most people won't spend $$$ on a tune and drive it the same as if it was stock.

hmmm, so you don't think the shift points on the stock tune are messed up? You have never had the HARD shift at part throttle from 1st to second? You don't get the HARD hit when you go WOT and it kicks down to low gear? How many cars have you tuned exactly? If you were correct then a car would never have improvements in gas mileage after being tuned. My last two cars were tuned with headers/cam/ported heads and believe it or not they got better gas mileage afterwards. Maybe you should read more fiction it might start to blend with reality for you

Question, what is the factory TM set at on these things? The only knowledge I can refer to is f-bodys. LS1 f-bodys for example had the TM set at 350 ft/lbs torque. It was anywhere in the power curve that reached that point, not just the shifts. Granted, an A4 car without TM would generally tear through a tranny very fast. But a lot has to do with the downshifts. A 4-2 or 3-2 will toast an A4 quickly.

Not True. A tune does more than modify the WOT values, it also modifies the entire timing and fuel maps, torque management in each gear, and upshift/downshift points. You will notice a difference even in part throttle situations, and can see an increase in gas mileage simply because the A/F mixture can be leaner at any time that you're not WOT, depending on how the vehicle is tuned. People that drive in a way to tear up their equipment will tear it up even if they are stock. A tune won't CAUSE a failure, but it may help them find the edge quicker.

 

Alright please refrain from throwing insults back and forth. Having a discussion is one thing but please keep it respectful. Insults won't be tolerated.

Unless you have a 250,000 mile TB/EN, it is hard to say what a tune will do in the long run. I'm sure if GM could increase the gas mileage while keeping the same reliablity and emissions they would have already tuned the vehicle differently.

Leaner A/F mixtures is not always better since fuel is also used for lubrication and cooling somewhat before it is burned up and sent out the exhaust.

Regardless, emissions is probably effected and probably not for the better.

As some one mentioned, you must pay to play. I'm all for modding vehicles (like that fantastic Lingafelter Vette in another thread) but there is always a drawback to a mod in some other area.

 

Excellent

Thanks for all the info guys, I think I decided to go ahead with the tune and keep my fingers crossed. I will definately be going through Vector Motorsports. Those guys really seem to have extreme knowledge with the LSx. Thanks again.

Cars are tuned from the factory to ensure the least amount of critical failures possible. This reduces warranty costs for GM. Cars are rated at flywheel horsepower and torque as part of a numbers game. It has been going on for 50 years in the auto industry. A lot of factors go into a factory tune. The cost of warranty repairs and the idiot factor are the 2 biggest. Even though they tell you use premium gas, they tune for 87 octane because they know a lot of people won't listen. They add in torque management because they don't want to replace the transmissions on the cars that people abuse. It is all a money game in the end. Does GM do things that they know will reduce mileage and increase emissions? You bet, as long as they can save money and come in under the regulated expectations.

 

1) We have a special case with the TBSS. A 5000 lb vehicle with 400 HP, with a transmission designed for a 3200 lb vehicle with 250 HP. An accident waiting to happen. Which is why there is so much frickken torque management programmed into our trucks, to knock down our power to 250 HP until about 3500 RPM.

2) A proper tune will do nothing to the engine except make it run more efficiently, so you don't have to worry about the motor. The transmission, OTOH, is a completely different story. As soon as you start removing torque management, you start playing with fire, potentially decreasing the life of the transmission (see #1 above).

 

Well Put!!

Everyone is free to do what they feel to their vehicles, I respect your choice but please don't knock my tune. :yes:


Life is to short to worry about every little thing, Enjoy YOURSELF & your RIDE!!:woot:

I don't know how I was knocking anyone, maybe the folks with the ignorant viewpoint that tunes are bad
