    Default Tuner/Performance chip

    Hey guys,

    This might be a reoccuring questions or even have an obvious answer but i am in the process of putting 35's on my 07 nnbs silverado 5.3l v8. I want to know the best tuner/programmer/chip etc to help with 35's. i have heard of most only going to 34" tires and even then the program or tune is not just right for the truck. If you cant tell im new to this end of the world and have literally no idea. any help is good help

    With the support of Lew I would suggest to go with a Diablo Sport product. If you buy the combo tuning/tuner he will work with you on dialing your truck in. I know that @SurrealOne has 35's on his truck and is close to getting factory fuel mileage back. But some of that has to do with a regear.

    How could you be worried about fuel mileage and want a lift and 35's?? The only tune that will be worth any money would be a custom tune. I have heard great things about Blackbear and also Lew's custom tunes.

    A custom tune as stated before and gear change. Most common is 4.56 but depends on your original gears (assuming 3.73). I put 4.10's and wish I went 4.56 on mine.
