I was wondering if anyone had a performance tune for my 03 silverado with a 5.3. My mods are EFI live, K&N cold air, throttle body spacer, flowmaster exhaust. i have a tow tune right now, which isn't much but i want more out of it.

 

josephb00, do you own EFI live or did somebody tune it with efi for you?

 

well my bestfriend owns it, he just told me to get on here and find a tune so he could put it on my truck

 

Hey Joseph,

You might want to check www.holdencrazy.com for some sample tunes.

i've been there before, but they don't have the 5.3, all they have is 8.1, and 6.7. they have one for a 5.3 but it is a 99 model with a supercharger... will that work though?

 

Yey Justin!
joseph, take some time to read this section. There is a lot of good info available here and people who can help.

 

Its not as simple as just finding a tune and loading it in.
