Any advice is helpful

Hi, I am new to your group. Glad to be here.I have a 2012 Tundra with a Bullydog GT programmer. I pull a 8900 lb camper and I am thinking about putting a Magnuson supercharger on it. I was wondering if anyone has had this type of setup? Lots of questions..... do I actually need to change fuel pump? When my pump went out a couple years ago, I had to get my computer flashed and had to reprogram Bullydog. What a pain! I run E85 most of the time. I know with the supercharger I will have to run premium for the octane. E85 is 104+ on octane, will it be OK to run with supercharger? Also wondering if I will lose mileage? I have read people lose mileage but is it because they can't keep their foot out it? I just want to pull camper better. Thank you in advance for any advice.

 

To run e85 with the charger will require a bigger fuel pump. Way bigger injectors. And you’ll get hugely worse mpg.

not saying those things to be negative. It would be beyond cool to do a supercharger on e85!!

 

You can run the SC on E85 with the supercharger.
Although the fit kit for the SC comes with larger injectors, fuel pump and the base tune. You most likely will need to have larger injectors and fuel pumpbthat come with the kit. You should browse around the supercharger forum for some info. It can be a lot at first but lots of knowledgeable people.

Another member who ran ethanol, although he no longer posts or has the truck anymore had to build up his fuel system. I'm posting it for informational purposes.
