Unless you hold it flat going up a mountain and the gauge is pegged for a minute or so you shouldn't melt anything. Be smart about your driving but don't be a pu$$y. If you don't want a bigger turbo you are limiting yourself pretty good. You have bigish injectors but I have overwelmed hx40s with stock fuel systems.
