You probably already know what the problem is - you have a 3 ton truck that is putting maybe 170-180 Hp down to the tires!!!
So if you want to add another 100 horsepower, you certainly can do that, and it doesn't have to cost a fortune. Now it is also true that *reliable*, safe & sustainable power doesn't come dirt cheap, as anyone who knows anything about modifying mod motor trucks knows.
Now all of that having been said, there are PLENTY of great things you can do to help get that truck motivated, and I would suggest doing your mods in the order of best bang for the buck - and that order is, first, have us do our custom tuning, as that is going to add an easy 40+ HP at the motor, and then next comes our intake setup, and then out cat-back exhaust - at that point, you are at our Stage 1 level, and that truck is much better off in terms of it's performance and driving enjoyability.
From there, it's on to underdrive pulleys and electric fans, the 2 of which will add an easy 20-25 more Hp AND you will burn less fuel all the time as well, thanks to the reduction in parasitic losses.
Now at that point, your total power gain is an easy 75+ HP, and well over 100 lbs/ft. of torque, and you haven't spent what a supercharger will cost, and you don't have to rely on a bottle for power (all throttle, no bottle for me). You will also have a much better driving vehicle that does not require a lot of other parts to make it work, and won't have hurt your budget badly.
There are any number of ways to get there, but we strongly recommend sticking with the bang for the buck route, as that way you get to the performance level you need for the least amount of cost.
I hope this brief info helps, & please feel free to give us a call at our number listed below to go over all of this in more detail, & we'll also be happy to answer any questions you may have, etc.
Best of luck with your truck, & thanks for your post!
