Went and meet Alvin at Pro-Dyno in Charlotte, NC. What a class act. Got the EFANS & Tune and,,,,, WOW--what a difference. The change is night & day. Big difference. Best bang for the buck. Truck put down 358rwhp. Efans install looks so clean. If you didnt know better you would think it came like that from GM. I'll try and post pics up if anyone wants to see.
Thanks again Alvin for awesome experience
