Yes you can. You've just gotta be "smarter than your equipment"... Check out HPtuners, LS1edit, Flashscan... They're all software programs designed to let you get your hands dirty, just like you did way back when. The engine itself is still the same & still works the same way they used to. The only difference is the "interface". No screwdrivers necessary anymore...bangers said:You can't do the work to a current V8 that you could do to the old ones (cos of all the computerised crap).
Tuners are getting up to 70 additional fwkw out of Gen3s. And that's without any bolt ons. Just from messing around with the computer.
