Please Do Not Run E-85 on Stock Injectors.

Will changing to the 47's require modification of the tune?

No.

No.

Thank you.

Um, changing from stock injectors to 47's will definitely require a tune change. Consult your tuner before installing the injectors to make sure you have the correct tune for them.

Really. I thought it was just for the E85 revision.

A larger injector will require the tune to be properly scaled for that size injector. The larger injector will require less pulse width to spray the same amount of fuel to keep the air fuels correct. E85 can change things as well. The tuner should know about the injector size as well as fuel type for a safe correct tune.

Appreciate the response. I'll contact Lund before doing anything. Running E85 should I see any improvement in performance? Not expecting anything radical.

Absolutely. There are about 12 injector tables that need to be adjusted for the larger injectors. If not you will run very rich.

Getting ready to purchase my christmas presents
Goin to go ahead and order the injectors to be on safe side.
Will there be any issues of running 47lb injectors on 93 or returning back to stock?

If you have a Flex Fuel tune for the 47's there will be no prob running E85 or 93. If you want to return to stock you will need to put the stock injectors back in.

Definitely the car would run really rich on the stock tune on those injectors. About 25% rich to be exact.

Thanks guys

I have the Flex Fuel Tune from Lund. I noticed the cold start starts up like crap with E85. Would the 47 injectors fix the crappy cold star or the injectors have nothing to do with it?

 

[Soonertim4]

Thanks for the info Terminator
Jus ordered my injectors

I'm assuming you mean it cranks longer on cold starts vs 93? Nope injectors themselves won't but adding more cranking fuel mass and cranking spark helps some. It still won't be as quick to start when it's cold due to the nature of E-85 (high ignition temperature).
