3.0L mods that work! any sugguestions?
I have 1998 300 promax super magnum's all stock on a 30 motion. I would like to get more power and rpm's out of them. any suggestions?
some say exhaust tuners and open up the mid section.
redo ecu's for more rpms
and performance reeds and blocks
what's everyone's opinion or experience
that's for your help!

To be honest from my playing with them on what I do tuners do not make any difference just makes them louder.
Get your ecu's limiters lifted but what box ratio and prop your running?
You can skim the heads and fit a aftermarket fuel pump and reg and up the fuel psi. intake like the svs or 300x style can do alittle.
