Installed MSD 6AL-2 with HVC II Coil
Installed recently, I'm using Iridium Plugs #6 Grade opened the gap to .48 I beleive it was .39-.41 from the box. I had to increase the fuel pressure a bit as I noticed the car was running lean. The car was tuned before I installed the coil and was running on 12.8-13.1 range at wot. This last Sunday I went to a Nissan Meet and Dyno Day, and the car was running at 13.7-14.1 range o_0. The only change from the time it got tuned to this other dyno session(show only, no tunning involved), was the HVC coil. I know that the OEM ignition system is very good and better than most aftermarket ones, but just want to hear some comments about this one
