hey guys i just bought a 07 tbss. i am wanting to get some tuning basics, also i was going to log the truck but when i select the default ls2 dash it does not work? last question, i read around that you can install and run efans with efi live just like you can with hp tuners. please any input would be great, thanks!!

You need to select the Default E38 dash, 07-09 TBSSs use the E67 not the E40 which is what the default LS2 dash is setup for.

Efans is easy, change some tables and flash it back is all thats needed.
