I love trucks but i hate the gas mileage on them... I'm also saving up to get a car I'm just going to keep my truck for weekend driving

I look at at like this, if you l live some where that you can't get a custom tune than a handheld tuner like a hypertec tuner is also good.

Not to be rude but this is absolutely incorrect. A good tuner can do a mail order tune that will be nearly perfect as long as you provide a full list of your current mods. The hand held tuners are crap, they lean it out a little and change the shift points to make you "feel" like it is faster/more power. The hand held tuners leave way too much on the table and they are in some cases more expensive than a mail order tune.

For anyone that wants a mail order tune for GM vehicles you can use Nelson's Performance in San Antonio TX if you can't get to a dyno or a speed density tuner. He has such a massive database of custom tunes that he can load the right one into a PCM and mail it to you, just swap it out and send yours back as a core exchange. There are others that do the same thing, Black Bear is a popular choice but you can research what works best for you but I would never recommend an off the shelf hand held tuner for anyone that expects real gains.

this is what i did. i didnt use Nelson but i know they are very good. i went with Wheatley in Houston, and i believe that black bear does mail in. i also agree that handheld are worthless just a waste of money.
