another tuner question

I have an 02 ls 2500 and i was wondering what kind of tuner would work best for a stock system. i have over sized tires and a 3 inch lift. and i want better fuel economy and towing power. but i also want the option to upgrade. along with the question what is a better heating system to put on? i live in NE wisconsin and the winters can get pretty blustery. Any info would be appreciated!

there is a ton of stuff out there, and most of it will hose the allison pretty quickly. just depends on what you want, and what you are willing to break. keep in mind anytime you start modifying any vehicle its gonna take on a life of its own. you juice up one thing and something else will give sooner or later. if your truck is totally stock and you don't want to get into other drivetrain mods, keep your new tuner under 100 hp. personally I really like my ppe, but that will tear the *** out of a stock tranny/clutch (ask me how I know). IMO you have about the funnest engine for playing around with, but just be careful it can get outta hand way too quickly.

good luck...


edit: sorry almost forgot about your heating issue. i had a friend who would hang two heating pads underneath the hood and put the power on a timer (like for the lights in your house when you're away). he would have problems when he left them on for more than four hours. sounded kinda risky to me but he did it for the three years that I worked with him and didn't blow up his truck. again, good luck.

if you use the winter front you will warm up quickly(5min) if you start driving, and wire in the high idle switch, to high idle in the winter
