So I am looking at buying a SC for my 04 HD 6.0 later this year. I am looking for more towing power, nothing street strip. Anyway I have been comparing the E force the magnuson and Whipple. anyone know how complete these kits actually are? I see the E Force kit says it needs the additional fuel pump assembly (if you dont have Flex fuel and I dont) putting the total price to $7227 on summit. the maggie kit says 100% complete and is $6500 on their site and per the instructions it shows replacing the FP. the Whipple also says complete and is $6700 but I cant find the install manual. I had planned to spend no more than 7K so the E Force is out unless its really that much better. I just want the best towing bang for the buck. I have always heard good things about Magnuson and Whipple. is either one better than the other for increasing pulling power? I'm leaning towards Whipple just from my past research the great reviews.

 

Get a hold of Brian at Superchargers.com. He's a member here and will take good care of you with whatever charger you decide to go with.

 

IF you have the return style flex fuel, ( Some 2004 still had a return fuel system, many do NOT ) the Maggie is straight bolt on.
Mine came with an inline Bosch44 booster pump, although the stock flex-fuel pump in the tank is adequate with stock MAGGIE pully, if you pully down for more boost, the Bosch044 gives you PLENTY of extra margin.
The Magnuson kit is VERY complete, and will install in a day. 2 BAR SD Tuning will take additional time, and is highly recommended.

 

Mines non flex fuel return less. I noticed the boost pump in the Maggie instructions and while that idea is good for performance, I dont like the idea of that added inline pump having the open electrical connection. Mine being a return less system it looks like I dont have to worry about it, but if I did I would prefer to stay away from that as I live in Michigan unfortunately and anything electrical that's not sealed becomes corroded nightmares especially under the vehicle.

 

Get the Maggie, they are oem reliable and faster than most want when turned up...
