Does anyone know if GIAC offers free upgrade to their X-chip..
 

if you're a current GIAC 'regular' chip owner? or do you have to pay a fee for the X-chip update?

Also, I was told they would be able to remove the 2nd O2 sensor readings if you were running test pipes, is this true? Thanks in advance!

Free upgrade...just pay for shipping

most places will charge you $25 for the upgraded chip
 

the only place i know that does free upgrades is awe-tuning.

Thanks! how about..
 

the 2nd part of my question? do they still do custom tuning for free? Or is there a charge? please let me know, thanks!
