Here's the situation. I bought an 06ss/sc with a locked up engine minus the SC. I had an lsj with SC laying around as a spare I picked up for cheap for my 07ss/sc. Any ways the 06 car was tuned for e85 and had the 80# injectors in it. My question is can I run 80# on 93 tune? (i plan on getting it retuned). I rarely see guys running over a 60# on 93 and that's what brought it to my attention. Anyways I've been daily driving the 06 after I put the spare lsj in it and I have these 80#s just laying around with the harness and want to use them if it doesn't involve much. And 2nd question, if I'm running 80# injectors would I need to upgrade the fuel system to accommodate the larger injectors? The car could possibly have an upgraded system since the injectors originally came out of the car. Does anyone know how to check to see if i do have an upgraded fuel system? Pressures? I have a fuel presure guage i could check but dont know if that would even tell me. Im not too familiar with fuel injection stuff. I have header and exhaust only on car now but if I could use the 80# injectors then i plan on buying a smaller pulley, intake, and a tune. Any info is a big help. And p.s. how do I add a signature on these posts?(mobile) Haha I'm new.

 

You will definitely need a tune if you change the injectors, but yes you can run 80s on 93. The car could have an upgraded pump but the fuel pressure would still be the same as stock, only way to know is to pull the tank and look.

 

Do you know if it would be ok to run them with a stock fuel system setup? Would it hurt the injectors or fuel pump possibly not keep up with them or is it fine to run that. I just haven't seen anybody pick a 80 over a 60 besides on an ethanol. Which I understand ethanol runs better on the 80s

 

its not going to hurt anything as long as youre tuned for it.

 

Alright sweet. Thanks for the info! Greatly appreciated!
