I've got someone to buy my 44lbs marine injectors so I'm considering swapping them for my 80lbs ones but I'm not tuned yet for them thats my only concern i don't plan on driving the truck i start it to move it outta my garage once and awhile till i get truck done to get it towed down to my tuner

 

It'll be OK moving from spot to spot. I had to run mine on the stock tune after the cam and injector upgrade at a dealership a while back... didnt run well, but it ran.

 

ill probably just throw them in and be done with it i keep beating around the bush plus i gotta do my adjustable FPR anyways so i need to pull the fuel rail anyways i just don't wanna hurt the motor after all this time and money lol

 

Just plug in injector data at a minimum, then go get tuned proper.

 

It is going to dump fuel out of the tail pipe, literally. Going from 44lb to 80's it may not even want to run, not sure who makes the 80's that you have but some of the 80's require vastly different injector data to get them to play right.

 

Injector data is the single most important variable in a tune. If it expects a 44lb injector and you put a 80lb injector in it, it will be extremely rich. I wouldnt drive it any farther than I can push it. So in other words I would push it that far.

 

I'd update it for him but Don at slowhawk used a custom operating system with EFI Live so I'm locked out of edits.

 

why risk it?

i loaded my truck on the trailer then swapped out the injectors

 

touche im gonna stick to my guns and just have my tuner do the injector swap when i drop the truck off

 

Itll run, I put my 80s in with a bone stock tune and it runs, I dont drive it obviously I just let it run enough to check for leaks and whatnot. And it moves on and off my lift, I backed the fpr as low as itll go to 35 psi and if it idles long enough the A/F gets up to about 12
