I'm looking to chip my car very soon but I need a bit of help.

From what I understand all of the chips gains are ABOUT the same. (APR is a bit more agressive - but does cost a bit more)

I drive my car 365 days a year and need something very reliable.

GIAC - is done through Pfaff Audi Tuning and was my first choice but I've heard good things about the others

REVO - Almost the same price as GIAC but for an extra $200 I can add the switch that allows me to change between stock and stage one in about 5 seconds.

Unitronic Chipped - Haven't heard much but I have a friend with one and says he's really happy.

Ok I'm ready for some help.
Advice Please.

 

APR has nice feature where you access it through the cruise control that was my first choice but then I found out about Vast they yield about 15 more HP than APR

 

APR really isn't an option. The. closest dealer is about 50 min each way when the others are about 10 min
I want a shop I can build a relationship with.

 

REVO FTW!
I'm in the midst of getting that installed myself on my B5 S4.
I leaned that way because I really did like the fact that you can put your car back to stock and not have your car constantly pushing power above stock.
I heart my car and try to do whatever is best for its health, lol
