you can run 11to 1 if you want to.but getting it tuned will be the best thing to do to get the best performance and you said your worried about gas millage.if your smart you will call the cam company and tell them the specs of you motor so you get the "best"cam for your ride.you didnt say any thing about heads so i will assume u have stock heads and a cam thats has good low to mid will be good if you have stock heads cuz they dont flow good.alot of people make the mistake of just trowing a cam in there car and not really being the right one.if u call a good cam company they will want to know the engine specs,transmission,rear end gear,weight of car.i am not saying the cam you picked is the wrong im just saying make sure its the best for what you have,just do your homework.i dont like comp cams because you can call them 5 times and get 5 different answers.as far as the fuel rails idk,id have to think they would,just test it out.good luck
