Hey all,

I now have a 2010 Tahoe with a 5.3 Ly5 i think...I have DOD and flexfuel option.

On my old 2006 Tahoe, i made all the timing tables the same which were the GM high table. Can i do the same for this new engine?

I find that the engine preforms better, and i always use 95 octane fuel. I do not mess with my Maf temp to timing pull.

on my new tahoe I have full length headers, catback, 1.8 rockers, Throttle body spacer and air intake kit. I am about to disable the P0420/P0430 due to my high flowing cats...The MIL is starting to bother me.

Looking forward to your replies
