If i advanced my timing 2 degrees (running high octane to prevent pinging) this would give me significantly more power correct? Isn't this basicaly what the superchip does (in addition to the tranny stuff)? I have heard of people running 4 degrees advance but i don't want to risk blowing the engine. I don't care about gas mileage but i want the engine to be reliable. Any advice?

YUP, that would be basically right.

a) you could probably get all the way up to six degrees advance without problems in most areas (and with premium) since that is about the amount of retard that has been placed on engines since the late 70's.

b) unless you are running an older model truck, there is no distributor to set the timing. Thus, you must change the engine timing via the engine control module and/or a chip.

c) the typical chip also changes fuel/air mix as well... similar to carb changes you might make if you were to advance timing. THe better chips will adjust both timing and fuel/air ratio, as well as shifts, through a wide range of loads, RPM's throttle positions, etc., and opposed to simpler implemetations which may change things at only one RPM or with fewer inputs.
