With fancy lingo such as "Big A$$", "Monster Ram", and "Boost tubes" there has to be astronomical gains in both power and MPG across the board, right?? I honestly have no clue but Banks does have a chassis dyno on site but they fail to post any results showing before and after. What you will find is useless flow numbers in which they test their products venting to open atmosphere. Would love to see data showing how these increase flow within the engine vs an open room. Here is my $.02 on their products below:
Pedal Monster: Yes, this will increase your throttle sensitivity and this is it. You can accomplish the same thing by mounting a small 2x4 to the top of your accelerator pedal.
Banks Exhaust: Purely cosmetic upgrade, 0 performance gains to be had from a post DPF exhaust upgrade. Save your money and buy a tip if you are after aesthetics.
Air Intake: I think they have a well designed unit here but the fact is you are limited by the stock ECU. These apparently do increase air flow and in most cases you will end up with an engine light having to do with your EGR, if I had to guess its due to the EGR seeing to much air flow. They will more than likely come up with some type of resistor to trick the ECU to stop triggering the engine light which will more than likely negate any power gains.
Ram Air Horn: Again, seems to be well designed but you are going to pay top dollar for this. There have been a few instances over the years in which the OEM grid heater bolt destroys your engine. This is extremely rare so its your call o if you want to dish out $$$$ to relocate grid heater. The design of these can surely support more HP than the OEM unit. However, on stock tuning and turbo I honestly don't know if there are gains to be had or not. People who have purchased these reported better throttle response but I have not seen any hard data or any before and after dyno gains.
Boost tubes: Members have reported better throttle response from these but that's about it from what I have read.
Bottom line is you will not see significant MPG gains on any modern HD truck no matter what you do. The biggest gains will more than likely come from custom tuning but don't expect big gains in the fuel economy department. You will see huge gains in power and drivability but that's about it. If you are after MPG, buy your wife a hybrid and drive that when you aren't in the truck
