Greetings..just bought a Deaschwerks DW400 and when my GT warms up I can hardly start my car. My mechanic saids it is defective: however, DW tech support claims I need their wiring kit because the fuel pump pulls 16-20 amps. I bought the wiring kit and plan to have my shop install it this Friday. Does anyone have simuular experinces? The u tubers show the DW 400 install but don't mention having to hard wire the DW 400.
