what tune

Tow/eco 120? I think you got that wrong. I've been installing the 60hp tune on the LML single tunes as long as they don't tow heavy. That's known as the tow/eco as far as I know and they seem to run great. 30hp is a tow tune.
Yeah they flat out run for a basic tuned truck!
Run all of it

Out of curiosity, does the LML tuning have the same power increases over stock as previous generations? Cuz doesnt the LML make like 100 more HP than an LBZ? So, if you can get a +230whp built trans tune on and LML that's like 330hp on an LBZ....right???
Unfortunately the LML has a weak fuel pump (cp4.2) which doesn't allow us to really crank on the fuel.
With the fuel pump replaced with one that will flow adequate fuel, the stock injectors can flow around 700hp.

The cp4 does not supply enough pressure on its own to maintain psi!
Your tunes are probably 60/90/110/130-150
Unless you have a built transmission
Lift pumps start being required around 90-110 over stock
So Kory, with the cp3 conersion, a turbo and a built trans, the stock LML will push 700...like an LBZ is "good for" 600???:baby:
Man honestly without a lift pump and maxing out the regulator in tuning we can generally hold close to 150hp over stock. The cp3 conversion and injectors will generally give up 700hp, sometimes a little more and sometimes a little less as long as the supporting air is there.
I cant say it will prolong the life, but i can assure you it doesnt do the opposite. I'm also not totally convinced that low rail alone is whats killing them, although i can confirm low rail doesnt help. They are just too hit or miss. A lift pump would be great preventative maintenance, however... And the option of the added power doesnt hurt either
For the record, you're asking some remedial questions here that can be answered by reading about how to buy a tune and what you get when you do. You know Kory is the tuner, so check out his site Maybe call/email him up and give him your vin or better yet the serial # off the AutoCal and find out exactly what it has...
That said. Stock trans tuning typically goes 60/90/110/140ish or around there...I think the LMLis slightly different tho it might be 30/60/90/130??? Something in there...
The lowest power tune is your heavy tow, that's anything the truck can tow, the 2nd lowest power level is your light tow tune and is rated for up to 8 or 9k lbs IIRC...the top two tunes are your street performance and competition tune and you don't tow or even haul anything substantial with those...but really if you want to watch your EGT gauge and press your luck with the Alli, you can try to get away with what you want to...
Take the time to search the forum for a few minutes and the answeres you're looking for will probably come to you alot faster than waiting for someone to take the time to type out a response:hug:

Really! That's pretty impressive. Now the tuning bridge has been crossed it seems like the LML'S are proving to be quite the beast of an engine!Man honestly without a lift pump and maxing out the regulator in tuning we can generally hold close to 150hp over stock. The cp3 conversion and injectors will generally give up 700hp, sometimes a little more and sometimes a little less as long as the supporting air is there.
After laying into the other guy...thank you for answering my remedial question I probably could've found myself
:baby:
:angel:
If you have a way to monitor EGTs and keep them in check it should be fine.
I've been running my ppei max effort tune for about 16000 miles, I rarely switch tunes, only if I need to tow
