any differences? do either of them offer more that the other? anyone regret using aam or t-square? thanks your opinions matter~

 

Get AAM. I know the guys there and they do nothing but great work...esp with tuning

 

Search my old dyno threads. Technosqaure did a great job for me in extracting a ton of power out of my NA mods. Also, I observed that at the last dyno day out here in So cal, the guys producing the higher end of power all had reflashes done at Technsquare

 

+1 for TS.
