i currently own a 2005 monte carlo ls with the 3.4L 3400 motor. im trying not to sound retarded but does anyone know the link where i can purchase a DHP tuner? also if there are any other tuners, ie superchips, jet chips, or anything else that would work as well? a friend of mine told me to do either a stand-alone fuel management system or a piggyback system. at this point im not sure what would be the best route to go, and in hp for my dollar. so if anyone has any ideas PLEASE post links or pm me

 

DHP went out of business a few years ago. You can find used ones on clubgp.com often.

HPTuners sells a tuning package as well.

You're probably looking at 250-300 for the DHP, and 500 for the HPtuners.

Unless you're planning on doing a lot of modding (which isn't really possible with the 3.4L), then you're probably better off finding someone local to just do a tune for you.
I'm not positive that DHP even supports the 3.4L (it was pretty much L67/L36 specific), but I'm pretty sure that the HPTuners suite does.

i was hoping i could find somethin a lil cheaper than that. along the lines of like a superchips or a jetchips setup? any ideas?

 

This is probably what you are looking for

I would also stay on the milzy site and look for some other things to add to your engine.
