So long story short bought a car w/ maft pro already installed and tuned by jestr. It runs really well exept when its cold just misses and leans out really bad. It will do this at cruising speeds every once and again. It will also throw a p0300 random misfire code also. Any settings for cold idle I could mess with? I have been spoiled with my se-r by using a jim wolf pnp ecu, never had to mess with tuning at all. Thanks in advance Chris
