Torque Management ?'s

Do you really want to go significantly more than 160 km/h in one of these trucks?

Most (if not all) chips that reduce/remove TM also make the transmission shift more quickly & firmly. So on one hand, the increased torque is indeed harder on the transmission. But on the other, there is less slippage between shifts which translates to less heat and wear & tear on the internals. Those factors cancel each other out to an extent.

Whether there's a net gain or loss in longevity depends on the chip and transmission. I'd recommend doing more research on your particular drivetrain. If the transmission is just barely capable of handling your engine's power and TM is used to make it get through the warranty period, removing it is obviously a bad idea. But if it's pretty robust, go for it!

i think i just might.....

Some mention "chips". Are chips the same as the old HyperChip I had in 1988? That is, one would order a new chip and plug it in the truck's computer.

If I understand, the "tunes" now available involve (possibly) having crankshaft to re-arm or re-learn unless I send in MY computer or part thereof to be programmed? Warning lights coming on, etc.? The non-original re-programmed PCM's are the root of many troubles?

There are no problems with the "hand-held tuners" as Mike @ Diablo sells?

I think it's pretty safe to say that technology has improved in the 19 years since you had that chip.

Since you have to remove the computer to install the chip, it loses power and therefore has to re-learn its adaptive strategies. But the same thing happens if you disconnect the battery. You don't have to reprogram it.

I have a Diablo chip in my '95 Mark VIII, which is a pretty complex car even by today's standards. I've had no drivability problems, warning lights, or any other issues whatsoever. It drives exactly like it always has, except it has a bit more power and the transmission is much more well-behaved.

On word: WHEATLEY

Just go to www.gowheatley.com and it will solve all your problems. One of the nicest guys you could ever meet. He is the one and only person in his business. Meaning you talk to the owner personally. When you call him he will work with you step by step to make a custom tune for your truck. Not to mention one of the cheapest prices, free upgrades, you can keep your stock tune too for future if you ever want to sell.

Charlie has done two of my trucks and about 5 of my friends trucks. I will have a wheatley tune in every truck from here on out. I have a permanent smile because of it.

My '03 that he tuned went from 12 city/16 hwy to 14 city/ 19 hwy and way more power. If I stomp on it from a stand still I can spin the G80 posi for about twenty feet. Oh yeah, 30,000 miles and not a single powertrain problem. No more TM for me.

Trust me, you will not regret it.

Handheld programmers only let you do certain things, a custom tune you can pretty much do anything you want. I was able to keep my stock tune and I have never had and any warning lights come on. 95 and older trucks had actual chips that they used, only good for maybe 10-15 horsepower. OBD-II ( 96-Present ) can go way more in depth and get better gas mileage and easily get 30-40 more horsepower for 20 minutes worth of work.

Just go to www.chevytruckworld.com and type wheatley into the search feature. You will see pages upon pages of satisfyed customers.

Why not? YOu can do 160 plus in a POS Grand Am from the 90's. These trucks are much more stable. And with the 20'' wheels and low pro tires, dont give me "not safe vehicle" bs. If I pay for the truck, I should be able to do what I please with it.

[Smaart Aas Saabr]

Yeah I agree.

It is a safetly issue. It is due to the speed rating on the tires, your load rated truck tires are not meant to safely go 100+mph & GM does not want to spend $350+ a tire for ZR rated tires just so you can go as fast as you want. Lets say someone went 130mph in their new Silverado, tires blew, bad wreck, somebody dies. GM would get sued for having a vehicle that did not have approiate equipment(or something like that). If you want to go really fast get something that is safe & meant for it. I dont want you flying by me at 130mph on the interstate & blowing a tire & taking me out also!

[Smaart Aas Saabr]

Doing 130 mi/h for a brief moment on a tire rated for 100, particularly when lightly laden isn't going to cause an issue. But assuredly, you should be feeling some notable discomfort doing so (eg weird vibrations etc) and shouldn't do it... put better tires...

There's also the issue of cargo flying out the back...

Looks like the only way to be able to return to a "stock" tune is to use something like the Diablo?

Can I take a Diablo and remove ONLY ALL of the TM and not disturb any other settings? I can't be sure from their site. In other words, is each adjustable setting (spark advance, air/fuel mixture, tire size, RPM limits, TM removal) adjustable without affecting other settings?

Just found this info from a DiabloSport dealer, ConcoursDirect...

..."However we have noticed that the shift feel when disabling toe upshift torque reduction in trucks and SUV's is reduced and therefore reccomended leaving it ON for trucks and SUV's"

HUH?

Using the factory HP tune you can make changes to the stock tune through the modified parameters menu.
I'd have to ask though, why?
Do you not feel the truck could use more power, better throttle response and better mileage?

Thanks
