well, my gf just got an 06 ecsb 5.3 and im jealous. im silverado/sierra shopping right now and i think i want to be a bit different and go for the duramax. im looking at the 03-04 timeline. anyway, while i shop, im planning my mods. what programming/tuning offers big power mode and also a mode for fuel economy? what kinda #'s do they generate? prices?
thanks guys...really appreciate the help

 

Well you should definitely go for an LB7 and get an Edge w/attitude, 4"or5" turbo back exhaust, intake kit from AFE and so on.... You will be very happy you did!

 

Then some injectors, a DTT twin turbo kit and a but load of nitrous, then you'd be rockin...

 

yup then a new trans!!

 

Fear those without plugs...
