Sorry if this has been asked before, but is a tune needed on a sr20det with walbro 255 fuel pump and greddy intake manifold? I'm asking because my car is still running very rich I think and has a hard time hitting boost. Also if a tune is needed would a wideband and fuel pressure regulator be useful to install before it gets tuned? I'm still looking for any vacumm leaks and the ecu isn't showing any fault codes but I just thought "well maybe it needs a tune." Thanks in advance for the advice.
