Whatever works for you. I have no issues driving into town to meet up and see if it will let us run a log. With the ECM, they are most likely locked and unable to be viewed in order to protect their tune files, but I think a log file would still be possible. Just takes a minute to hook up and then some drive time, file save, and an e-mail with the file.

 

Mucho thanks!
I'll have to figure out my schedule and get in touch. Mom is in hospice care and things are "crazy" right now.

 

Not sure if anyone is keeping this thread's first post updated, but here are my latest times from tonight. Was trying to work with the shift points but they are too erratic to do much with at this point. Hopefully I can get it sorted soon as only 2 of the below runs I stayed in it through the 1/4.

Truck weighed 5770 lbs with me in it and a 1/4 tank of gas. Full street trim and with the 22" wheels and tires. Truck now has 3.73 gears installed and I am starting to spin with the Nitto 420s despite AWD at the track. Although not running as good as I believe the truck should and having issues with the rev limiter, tonight provided a new personal best for the Denali at 12.839. Looking at some of the other time slips it is clear that there is more left in it just need to get together a good trans tune and a good run if the stock 6L80 will hold on.

 

Save me searching, what was your best with your last set of gears??

 

bdubb good times slap that LS9 cam and I tell u what low12s chit you might hit 11s

 

Just sold my motorcycle last night, the truck is about to get some serious love.

 

and it begins!!!!! So spill the beans what's the list lol

 

Working with Roger right now. I have gone back and forth of going NA and FI and he sent me an email last night that was pretty enticing to head the FI route. Looking at a Procharger D1SC kit right now.

 

No problem, it went a 12.89 at 105 mph or so before.

The 3.73 gears made a better improvement than what the 1/4 mile times show above in my opinion. Just need to get together a good pass and not have any shift point issues.

I would go as far to say that the current setup should be good for a 12.75 to 12.80 with a good pass. A new flywheel and 2800 Circle D stall should be ready sometime next week. Just hesitant on if I want to go ahead and install it once I get it or wait and do the 6L80 build which is going to hurt the pockets some I am sure.

The LS9 cam swap will probably have to wait until late March or April.

 

For sake of comparison...

2/25/11 - working on the WOT engine tune and hot lapping the truck


2/10/12 - Added 3.73 gears, truetrac, and 40k trans cooler. Somewhat hot lapping and working on shift point tune changes. Same engine tune as 2/25/11 runs.
