I haul cars for a living and I was wondering which would be the best for towing and fuel efficiency

 

The quadzilla XZT box was specifically designed for towing. It was one set hp/tq that is not adjustable. A lot of members here will recommend it.

 

so you prefer the single stage rather than the adjustable, i figured the adjustable would be better for fuel mileage in different driving conditions

 

It's all personal preference. I prefer single stage because i can't trust myself to stay on the low setting. The XZT box is just designed for towing with cooler EGT's and what not. So im just throwing out a box that sounds like would be good for you.

 

Do you remember how much it cost, and how much hp and tq gain it gives you

 

it can be had for 269.00 here at the DTR performance shop. Link on top of page
the Hp/tq numbers are 65hp/165tq

BTW Welcome to the DTR, just hang on to your wallet cuz it gets crazy

 

also horsehauler milford,oh is that the one just outside cincinatti

 

yep, sure is

 

What are you hauling w/?. The quad box is an excellent product but there are other options as well. Fill out you sig. and the knowledgeable members on this forum can probably answer your question better. I agree w/ you, adjustability is always better.

I assume you don't have gauges. W/ an '05, I would not hesitate to change the intake, deal w/ the muffler and then go w/ the Juice w/ Attitude. Now there are going to be people that are going to get all mad and recommend other stuff but that is my opinion.

well you know what opinions are like, everyones got one, myself, I dont know enough to have an educated opinion, but hey I appreciate it, one more thing what kind of intake you suggest

 

I would look at the Quad Intake first and then the AFE. I have the AFE but I have heard nothing but good about the Quad intake.

 

Juice with attitude. I like all the extra features and ability to adjust low boost fueling on each of the 5 settings. The egts stay low. I can tow on level 3 no problem.

 

putting a box on should I go ahead and get gauges for it
