Which tune level for stock LML with stock trans?

[thunder550]

Ordered delete parts for my LML. Going to order tuning from Ridge Runner, can't decide which power level to go with. Truck has stock trans that I would like to keep stock for a long time. Looking for recommendations for power levels for two scenarios: 1 - no lift pump, no line pressure controller, and 2 - Kennedy twin pumps and BT line pressure controller. Truck is a DD and does occasional towing. Primary reason for tuning is removing the dead pedal, and the increased fuel economy from the delete is a nice side benefit.

With lift pump and line controller, I'm pushing 13k miles and haven't left the max effort tune yet. I daily drive and tow with it. Trans hasn't missed a beat. Not recommending that, but just giving feedback. 26k miles on the truck

Realistically, you slap on a responsive, torqy 400-425hp tune and the trans should live a long time and the truck will be fun on the street. :thumb:

At this hp level what else is needed downpipe, intake, ext for both scenarios? I'm in the same boat as the op.

I have a downpipe, egr delete, and exhaust on the way. I think I'm going to go ahead and do lift pumps and the BT line pressure box too. Sticking with the stock intake, I don't see any reason to upgrade right now.

Its worth 40hp on a stock tune http://www.duramaxdiesels.com/forum/showthread.php?t=63908

Ahhh more parts to order. Wife is going to kill me, lol. That thread looked like they were running the oiled S&B filter, but I didn't see whether or not the dry filter gave the same gains. Any ideas? I'd rather run the dry filter if it's all the same.

I say go for option 2 :thumb:, Is there a additional filter option with the kennedy?

 

[thunder550]

Yes. I have his twin pump setup with the mega filter (big Baldwin filter) plumbed after the stock filter on my LLY. Probably do the same thing on the LML.

 

[thunder550]

Just ordered the Kennedy twin kit with mega filter, the BT Line Pressure box, and the S&B dry filter intake as well. This is getting expensive damn it! Now just need to decide on power level for tuning.

Better to ask for forgiveness than permission right?? :roflmao:

So...parts list now is

MBRP downpipe
LB7 up pipe
DRP EGR delete kit
Flo pro 4" exhaust
Corsa muffler
S&B dry filter intake
Kennedy twin deluxe pump kit
Kennedy mega filter
BT line pressure box

Dry filter w/filter sock is what I ran the tests with.

I'd contact Tony and ask his opinion on the safe power levels. I ran different tuning on a stock trans and then MikeL pulled the tranny apart. There is a write up on it in that same link as the air filter on what we found.

Thanks for the clarification.

I tried to call Tony today but his shop is closed til Thursday. I'll try to catch up with him then. Thanks Rob.
