If you own a 04' 5.7L GTO step inside

[BAD LS1]

I now have HP Tuner's software for the 04' GTO's now.

Send me a message or ask a question on here if your intrested in having your cars PCM tweaked.

That correct, 05's are a good deal more expensive to get the unlimited version.

A few members wanted their 04's done so i got the unlimited.

O5 AND 06 are not OBD II thay are CAL totally different plug and software.
