Thread: Utah GXP tune

Have a stock 08' GXP that I'm looking to tune in Utah, can't find any shops locally and I don't want to spend a ton of $$, what are my options here? Looked through previous posts couldn't find anything, my apologies if this is the 252525 time this question has been asked. Any idea what kind of gains to expect, if any, out of HP Tuners for this vehicle? Thanks in advance.
