Haha, I startrd hypermiling the same way as you. Not to commited and now I try to find every way possible to ecomod my truck so I'll get better gas millage.
Best thing to have to get the best possible gas millage without heavy ecomods, just start with a Vacuum gauge. With it you'll know if you're accelerating to hard or to soft. There is the Ultragauge that is pretty awesome to monitor your car's efficiency.
