Effects of reduced torque management

soccermom · November 5, 2004

I'm thinking of getting a Westers dual tune for my 6.0 HD. Those of you who have made that mod, how much torque management did you have removed and what effects have you noticed (good and/or bad)? Any insight would be appreciated.

Ive had the 89-93 dual tune for a couple months now and have not noticed any ill effects from reduced torque managment. I had Lydon take out as much as safely possible.

One of the best things of the tune is that I have much more power and mantained the same gas milage.

Im sure there are more guys here that will have more input - that have had their tunes longer then I have.

This is a very good question. I am interested also and would like to know.

Has anyone encountered any warranty problems with a custom pcm?

I would like to know as well.

I've had mine since april and have 15000 miles so far and no problems. Lyndon gets pretty detailed when asking about want you want for your custom tune,such as tire size any engine mods changing of the top end limiter and torque management. Usually everyone leaves that up to lyndon as he knows how much to elimanate without hurting anything. As to warranty I've not had an issue with that, but have asked the service techs and they say that they wouldn't know whether you have a custom tune or not as it doesn't show up on the scanners. It made a big difference on my 6.0 as far as power and tractability. The mileage increased also until I put on the topper then it went back to about 14mpg I'm glad I did install the custom tune I went with the 91 instead of the dual as I don't tow a lot but haven't noticed any problems when I do tow. Maybe tom from tbyrne will have another sale on the westers soon

I have the 93 hot tune and asked to have all TQ managment removed but it is still sluggish out of the hole. My mileage went up alot. I was getting 8-9 c and 11-12 h with stock pcm and 33's now I get 10-11 c and 14-15 H with 35"'s

Did you talk to lyndon about that? I know that with 33's it will slow down a little but with my 91 tune I can light up my stockers with no problem at all. I don't have to power brake or anything to do it even with the topper which adds a little weight. One of the dealer techs has a westers on his 02 and had problems at first. He just contacted lyndon and had another one sent out and it works great

I forgot to put 35" tires at the end but ya I talked to him and this is my second pcm. The first didnt rev out and the low end was the same as stock. So I can live with this for now untill i change something else.

When I did my Investigation into Torque Management I discovered that it begins to reduce engine power just passed 3,000 RPM. After much discussion it was determined GM began reducing engine power at that point so the average driver doesn't feel it. Removing portions of Torque Management will not add harm to the transmission. What happens is instead of reducing engine power at 3,000 rpm it will remove it later near 3,500 RPM or 4,000 RPM. Reducing TM by 80% would mean somewhere near redline TM would introduce itself and pull timing by up to 15 degrees, which is what it would do anyway. The driver would feel like the truck is falling flat on its face just before shifting whereas it isn't really noticeable in stock programming. Removing just a portion of TM would greatly improve city driving where power is needed in 1st gear. Mileage wil improve because with less Torque Management, more torque is getting to the ground requiring less use of the throttle.

TM by design is from 0-5 MPH or less than 1600 RPM in 1st gear and the 1-2 upshift. I don't recall any during 2nd gear or the 2nd-3rd upshift. I could be wrong. Too lazy to look.
