Propane is a really touchy thing because of just how it detonates, it's really hard to make a diesel fast with propane to say it simple, but darn you can get some good mileage with it. Meth injection would only benifit me for lowering my egt's but since the truck is only going to see the track 11 seconds at a time the egts can skyrocket for all i care.
