04 Silverado SS tuning

[bentley429]

Just picked up EFI live to tune my truck(04 duramax) and my buddies 04 SS. I am not quite sure where to get started. His truck has longtubes no cats and a magnaflow catback. We are looking to get the rear o2 sensors to shut off so it stops throwing the cat code, for it to make a bit more power and work on some tranny tuning. Does anyone happen to have a tune that would get us started in the right direction? Thanks.

I have the same truck but I don't have long tubes. I posted a log file on here a while back that if you can find it may help you. I am getting ready to do a cam swap so I will be out of my current tune in the next month or so. I don't know what other mods he has but I have tuned on mine with a CAI, 160* t-stat, Magnaflow cat back, and torque management settings. PM me and I may be able to help you with the whole tune. I am new to tuning so it is a conservative one.
