Re: Spark plug gap

The tune itself is fine car runs great just dumps too much fuel at idle. Tuning can't fix hardware, the 80s don't like to run below 2ms pulsewidth, and you end up running slightly less PW than that at idle with a little 4.6, with a 5.4 you have to do all the tricks to get load up at idle and get the PW up above 2. When you are below 2ms the injectors just dump fuel and you run 11:1.
