kayakman when you find out the "best" chip let me know so i can do the same.....

 

GIAC is more... ok a lot more aggressive the REVO is meaning boost will come on harder than it will in revo... downside is you will have a LOT of torque at the beginning of your power band so when your driving it's a lot easier to get into boost even if you don't want to be. I ran the GIAC file in my A4 when i had that... however I was running their PC-16 file (K04 upgrade) and it was Torquey at the low end! The thing would get up and go... but then quickly die off...
