LB7 upgrades help

So I just got the 5" straight pipe installed so that leaves me with an edge attitude tuner and exhaust done to the truck. Where should I go now?

The truck itself feels pretty week especially after 50+, and the shifting seems kinda funny almost like it loads up maybe its a diesel thing? It's my first diesel.

I want to do tranny so im saving for that, I was thinking maybe selling the edge and getting an efi live tune from danville, heard nothing but good stuff about them. Whats everyone think?

Also, if my tranny has problems like slippage etc, can i still build it up or do i have to drop more money into it? Thanks for any help!

Welcome !!! And EFI would be the best thing for your truck if you choose that route. Along with a built tranny that thing will feel like a built drag truck compared to that Edge tuner you have now. I reccommend ditching the Edge and going to either PPE/ATS or EFI live. Then the tranny build can come. As far as "beefing up" goes, theres not much you can do to the 5 speeds other than build it right the first time. Good luck !! Have fun

getting rid of that edge and upgrading to efi would be the next thing I would do along with a intake if you dont already have one. Then as you stated a transmission would be the next step. Then you can raise the tune some and grab yourself a lift pump to keep the fuel rail pressure up. Depending on what you want to do with the truck you could beef up the front end by add some tie-rod sleeves, and a set of cognito support braces. After all that is all said and done you will have a well built truck thats a lot of fun.

I havent heard any good things about the edge, so i would ditch it and go with something else. have heard efi is the way to go.

How hard is the installation of the airdog and the intake horn? I wanna knock out as much as I can by own installation and take it in for the bigger stuff. I'm no diesel mechanic but google and youtube provides a lot of help for installing things lol.


How fast should a stock lb7 be? Mine is really slow without the chip, a lot slower than the lly i test drove the day I bought my lb7. My 02' ford dually with the v10 would wax the floor with it. Not tryin to have a debate or anything but im just wondering.

Thanks for the all the replies so far!

Just make sure you change the oil regularly, fuel filter every 10k miles, and make sure all your fluid levels are good. Look at and smell the tranny fluid. How many miles on the truck? An LB7 can be very very fast with upgrades. I agree they can be pigs stock, but tuning (EFI or PPE) can really wake them up. Build your tranny, add lift pump, and you will beat most trucks you race against. You'd have no problem outrunning that V10 then lol

Thanks Dmax! There is currently 132k miles on it. I read the manual, and someone wrote down the services done, changed all fluids including differential oil, etc. All 8 injectors were replaced about 20k miles ago. So looks good there.

What would be better? Someone told me ppe is better and most others say efi live is better. I like the occasional smoke tune if i had a choice im not into smoking people out but it does put a smile on my face when i see it rolling out my exhaust lol.

Tax time sounds like the best bet for the tranny. The truck is new to me so its hard to save up $4200 when i spend most my money in diesel, haha. I would say with the chip it would pretty easily dust the v10 lol.

Thanks again man!
