I have the LB7 with Edge attitude with juice and i am wondering what a good setting is on the low boost fueling and power setting. Right now i am running level 3 and stock low boost fuel.

What are you trying to get out of it?Irun all of my upper levels (3,4,5,6)at 5,but I dont care about mileage.

i want power but i dont want to ruin any parts. i dont know much about this truck or components yet

and lots of puff

You are safe (more or less) up to about 100 hp.Depending how hard you beat on it.I usually run mine on level 3 or 4 all the time,no de-fuel except 4-5 shift and low boost fueling maxed on levels 3-6.I do get on it once in a while on levels 5 and 6 and have never limped it.I usually dont go into 5th under full throttle either.I do run synthetic fluid on it and change the spin on about every other engine oil change.Also,ANY time I give her hell,I use the tow/haul too!
