I ran a fass.on the Cummins what's good for the lb7? 2 micron filter? Then transmission. How do the head studs hold up on these engines? I want to do Efi live. Maybe just a single tune for milage for now. I have a Pyro gauge in the truck currently thinking mechanical boost gauge then an edge insight to round out the gauges.
run a DSP 5 efi live tune, and don't look back, there are several great tuners out there to choose from, head studs are good to close to 35-40psi (I think) on the LB7? but are a nice security to upgrade. Fass, air dog, Kennedy, any of these are going to be a good fuel pump and filter, you will get mixed opinions but all will do the job you are looking to do
Yea I don't want to build power then break everything like I did with my first truck. So lift pump Efi live tranny head studs then turbo. I'm nervous with this unknown programmer I don't want to start ruining things with a plug and play. My injectors and cp3 should be up to snuff to do 500 hp correct? Basically just turbo and tuning for the power adders to make that power
Primary concern to me would be the lift pump and better filters, then in as short of order as possible I would get A efi live tune to overwrite the unknown tune file and just keep it in the lower power tunes, then build the trans, then do some intake stuff and a turbo, upgrade engine internals and then add fuel:woott:
My list would be lift pump(I like the KENNEDY pumps, VERY QUIET!), intake(not required, but won't hurt), exhaust, built trans(5 speeds don't play well much over 400HP), boost valve, and a good EFILIVE custom tune. For 500 theres no need to spend the money on a turbo, just add in a boost valve to get it up around 30-32 pounds of boost. MANY people have run these same combos on LB7's and hit 500-550 at the wheels. Yes a turbo will help clear it up at that HP level, but not required.
Very good info
Yes you can get 500hp out of the stock turbo, but you have to drive it very hard and frankly it's harder on the motor pushing a turbo out of it's efficiency range. If you want to drive around all the time on a 500hp tune I would suggest getting a turbo or upgrading the IHI which is also a great option.

Not correct. Remember....you arent at 500hp in every gear, all the time. It'll only be 500 at WOT....do you drive at WOT all the time????
YES....
You don't
?
:rofl:
The only time I'm not w.o.t is when I am just cruising, even then it's not all that often
and I DD my race tune
and I agree with PAcouger, if this is the intended driving style, then a turbo upgrade is pretty essential, even though the stock turbo "can" do it, it's not really meant to do it, pushing it all the time is asking for trouble, an upgraded charger will run cooler, with less drive pressure and provide more power all the time, when properly tuned, and because its working more consistently in its map, it will be more reliable in the long run
Just my opinion, based off little experience, and a lot of research :thumb: and a lot of money spent with very little complications and breakage
