Can anyone who has purchased / installed a TRD supercharger provide some feedback on how it works, gas mileage before / after etc.? Does the power increase come on linearly off idle or is there a discrete boost at some higher rpm? I need to do something about the power for towing and trying to weigh the options of getting a supercharger vs. just taking the hit to trade the truck off to get a 3/4 ton diesel truck. A supercharger costs over $4000 with install and re-map plus have to go to super-unlead which costs the same or more than diesel. If the fuel mileage is hit pretty hard then it becomes a lot more economical to just get a diesel. Plus I can make my own biodiesel as well.
I love my taco and it is running like a dream. It is just seriously underpowered for anything other than regular driving around (works great for that) and installing a SC approaches the break point as far as return on investment goes since I don't think the cost can be recouped on resale. I checked on trade-in value for my '09 access cab and it is between 18000 tradein to 22000 for a private sale. So even for a private sale I am immediately losing 6000 plus the almost 3000 I spent fixing what was wrong with the truck new (and Weathertech mats also + rubber mat for the bed). I really get slammed if trading the truck in...way more than the usual 4 to 6000 dollar hit on top of the expense of the new truck.
So the addition of a SC is a pretty serious expenditure and represents a break point in deciding to keep the truck or not. I would rather keep it but the truck will not tow like I need it to and that is my fault for not doing my research and making an impulse buy to start with.
Any feedback on how the supercharger works and the resultant gas mileage after the install would be greatly appreciated.
