Boost timing

Personally, I'd recommend the Accel 300+ & 375+ Combo.

Way more features than the 6AL and Digital 6 offer, programmable with a handheld remote too (that also functions as gauges). No Dial/Switch crap to mess with, you can put the ignition components out of the way and use the remote to handle everything instead.

I have the 300+/375+ combo on my vehicles and love it.
