Well that is a relief for the time being. Yeah once these parts are installed I want to wait and get used to the feel of them before doing the 178 pulley and upgrading the fuel.
Thanks for the help!
Also, you said you tried stacking? Did you not like the feel of it or was it tough to get it running right? Would new injectors with that fuel pump help with that leaning out?
