Ok Im upgradin to 265/75 tires on my duramax, I tow a 28ft enclosed race car trailor with all the goodies, Im guessin 12-14,000 #s. Here is the question

WHAT BOX IS THE SIMPLEST TO INSTALL AND OFFERS THE BEST BANG FOR THE BUCK? I get enough noise outa my turbo mustang so I want no big pipes. Just add another 60 hp or so safely!

Diff of Predator and Edge?

What year is your truck, is it LB7,or LLY?

It is a early o3 how to you tell which one I have?

Juice.

You have a lb7, the lly came out in 2004.5 I would recommend you get tts power loader 3 soon to be released. These tunes are very refined smooth and have it all. They are simply the best, read through the forum to help you make a decision. My 02 cents

Edge Juice IMO. Check here with the vendors for prices. Some good deals now.
Ben

va 70/110 smart box e is another good one, or a power pup programer, both give around the 90hp/240lbs to the rear wheels, no gauges needed, good mileage, smartbox E offers tranny protection, power pup sells for 350 dollars, 550 for the E, freinds that swear by them after 2 years, more info pm me

Opps.
Forgot the VA

Good Module as well.
4 different versions available
regular
hot
spicy


and 'stoopid'

'stoopid' has NO TRANS PROTECTION NO DEFUEL. So... ya wanna run this one... get trans first.

I also pull a 28' race trailer weighing about 10,000 lbs. Have been extremely happy with the Edge Juice on level 1 towing and level 2 around town empty. EGT's are in pretty good shape at that level and truck runs very well without any downshifting out of overdrive on the Allison.
