Hi, friend has a 2010 Silvy, swapped out 5.3 to 6.0 on 243s, Torquer V2 Cam, 3600 stall, FBOs, 4.11s wanna run it on 93 octane, GEN IVs especially with DOD seem like a pain idle tuning due to all the VE tables etc.... Already contacted Frost for a flash but No Reply, wanna know of any good Mail Order tuners to get idle up n running good for drivability etc....
Thanks!
