Tryin to get more power out of my 5.2. Thinkin bout Hypertech max energy but don't really know much about them or anything else do besides major stuff. Any suggestions?

 

i have heard that Hemifever is the guy to buy from, so i ordered mine and it iwll be here tomorrow.

 

yes the sct tuner from hemifever

 

So how do I get hold of this hemifever

 

hemifever@aol.com

His name is Sean, and he has awesome customer service. Tell him your PCM part number (located right on the front of the PCM, easy to see), your model year/engine/etc., and he'll get you set up for less than $300.

 

Sweet! Thanks guys.

 

worked for me. sorry have nothing to compare with cause I just went straight to this. lots of people selling snake oil so one can spend lots $$ trying other stuff.
dont expect miracles but woke mine up a bit and like said customer service thru hemifever is stellar.
