another BB tune ordered

[keruzam93]

I just ordered my BB tune a couple mins ago. mail order tune because i have a 96. my order form went like this--


93 octane
no speed limiter
firm shifts
100% TM reduction


i cant wait for it to come in, i wish there was a dyno around here so i could do a before/after. oh well, with everything i'v heard on here about BB tunes im sure it will be noticable

sweet, it WILL be noticeable...but give it a few days after you install it, to get full computer enhancements.

what kind of mods do you have going along with this tune?

Please excuse my ignorance,but what is "100% TM reduction"..?

I myself may have also aked for a slight timing advance,and maybe an EGR delete.Also if you de-screened your MAF,that would also have to be accounted for.Im sure you did'nt,just saying.

Normally with a timing advance,it is advised that you run a cooler temp thermostat.

Please let us know what kind of difference you noticed with the BB tune.

TM= torque management

Great link, that explains a ton. Just what I needed to know before I order my BB tune.

I have 100% as well taken out....

the trucks stock as of now, i made this the first thing i did because everyone says its the best thing you can do with your money. and with free re-tunes i didnt see doing this first as a problem anyways

I didn't know what to pick with my BBTune, so I opted for BB's default which is 75% TM reduction on OBS trucks.

So I was curious why you picked 100% reduction. Is it because that's the default for NBS trucks? Or did you have your own reasons?

BTW, that link is 17 pages long! It took me a long time to read it all, even though I couldn't see the graphs it helped explain alot. Thanks for posting it up!

Not a bad plan at all! Maybe just order a second PCM from them so you will have a truck to drive when your waiting for the BB PCM to be re-tuned!

Justin did a live tune, he pretty much said 100% is fine on a 4.8, and I had a new tranny, and was out of warranty soon anyways. So I took his reasoning as gospel to me

i know you wernt asking me but i picked 100% reduction because they told me my 96 had almost no TM stock so removing it all wouldn't hurt

and im not gonna be sending my stock PCM back so i can still have a truck to drive during re-tunes

So for those of us with "old" tranny's (IE 168,000 miles) we should look at 50-65% TM reduction...just to be safe but still gain some power. (especially if we tow)

2000 Tahoe Limited (5.7L)

no clue then haha

Come to think of it, I just assumed my TM reduction was 75% because of thier FAQ's. But because I left it blank in my order sheet, they used thier default. Technically I'm not 100% what they did to mine. LOL.

I got this from thier FAQ.

How much torque management do you typically remove? Is this what cleans up the shifts and increases responsiveness? How will this affect off-road driveability?
Ultimately, we leave the torque management reduction up to the customer. On a mostly stock setup, we typically recommend removing 75-80% from the transmission during everyday driving mode. All engine torque management is typically removed.

You can read the rest of the FAQ's HERE.

EDIT: After re-reading this it seems that there are two TM tables? One for the engine and one for the transmission?

What does removing the TM from the computer do for your mileage?
