What do you think, go with the APR ECU upgrade or the GUAC chip. What are your personal experiences with either of themthem. I have no idea which I should go with, but was thinking along the lines of the APR upgrade as I live in a 93 Octane rich area, and live near an APR Dealer. Thanks for your thoughts!

 

GIACC! I love it and every place I have gone has said that it is much better than the APR! My boost spikes at about 21lbs it really made a difference in my car

 

Well I can tell you, if your running the GIAC And it spikes at 21lbs your turbo are going to go alot sooner. But I'm not sure what the APR spikes at either. But I don't think it spikes that high.

 

Look down nuff said go with APR
