What is the best tune I can get for a 04 Silverado with the 5.3. How much does it cost. Custom or off the shelf tune?

 

Id get a custom in person tune from one of the sponsors if you at all close to them >>>

 

any mods?

 

Do yourself a favor and go with a tuner that has a great "fan base" such as BlackBear Performance, Nelson, Wheatley, Westers or find a local tuner that has tune and test days.

 

It is nice to have tuning options.
We own EFILive, HP Tuners, Tuner Cat II, Tuner Cat II Road Runner, JET's DST, Wester's Duramax Diesel Tuner for Gas tuning. We have the ability to add parameters to the Tuner Cat based tuning software. This has allow us to do a lot of work with guy that do swaps. We have over 140 Electronic Throttle Control parameters, about 65 Flex Fuel Parameters and about a 120 fan control parameters for 1 meg PCM's

We have tuned several Performance Truck Net members PCM's. We have unlocked several PCM's for customers over here. If you purchase a product from us we will not lock it like other tuners do. It is your tune you purchased it. On that note we have a lot of those tunes from locked PCM's if you would like one of those.

 

I live in houston is wheatley the best option, because for the price they seem to be the way to go. Also would i get a better tune if i went in person to wheatley?

 

In person is better

 

Agreed. Nelson or Wheatley.

 

In person will always be the best bet, second best option is to get one done over internet.
