80 lb injectors will run out of fuel pretty close to the same time those 255s will.

you're well within the limits of the 80's and they'll have room for you in the future

80lb injectors will do 600 on gas or e85, not sure if twin 255s will do that on e85, probably.

80s are the ****, approx 325 dollars for the whole set.
hard to beat their flexibility and price

Sorry to thread jack but it is related. I am in a very similar boat, is there a specific 80 lbs. injector brand/company that you guys recommend?

Denmah, you give base tunes for E85? I've got a stock cam 5.3 with on3 76mm and those same 80 lb injectors from you're commonly bought items thread. A base tune to get the car running on e85 and maybe let me squeeze a few PSI out of it to check for issues would be great.

Ive fired it up on gas with the stock injectors to make sure everything was in running order. Was wanting to get a base tune from my local tuner so I could drive it there but he wants the full price of the tuning up front for it.

i only have an e85 tune for megasquirt 1 and 2, nothing for the stock computer,
honestly i am not a fan of e85, race gas is easier to get around here

E85 is at the gas station on the corner. I've used it in other builds. My last car had MS2 but honestly I would like to stick with the stock computer without a piggyback.
