You know, i've never seen the USAF logo on a GP but I kinda like it! Welcome!!!

I'd save your money on the ZZP tune. Just have someone tune it that has a HP Tuners Suite. Or buy one and learn to do it. They go for about 600 but if you are already going to buy a tune from ZZP that's 100-150 that you could just put into having your own tuner. Plus if you get good at it you can make your money back.

I have my own but I don't mess with it enough to remember anything. There is guides on here to do basic tunes with the HP Tuners set up too.

Just an idea for ya.
