yes, bolt on a new or used vortec, install rising rate FMU, colder plugs, and set boost for 5-6 psi, and install larger injectors, expect about 280-290hp, maybe more if you can get TVT or inmotion to do a custom tune. I posted the DIY thread on the forum via MBworld. do a search for vortec install.

the guy at inmotion is a bit of a pain, because he won't provide us with the software technology to do V8 installs even though he has the ability too which sucks for us, he's really not interessted in doing low boost tunes, because he feels it's awaste of time, he's more interested in selling Nitrous tunes to the NA guys, but I'm sure he'll do what ever you want him to do for the right amount of $$$

split second ecu is about $350 and allows you to retard and advance timing much cheaper if your doing dyno tuning

after that you'll have to install a set of shricks AMG/srt6 camsfor more power. also an oil cooler would be smart since the oil sprayers are shooting hot oil on the back of the pistons.
