i need some help deciding
 

well i orderd my pro 5.0 shifter yesterday, it should be here in a few days. my next mod is going to be gears, im still not sure if i want 4.10 or 3.73. im not planning on putting a S/C or N2O. i drive on the freeway at least 15 mins on my way to work. im leaning toward 4.10s but im not sure, i hear 4.10= +500RPMs & 3.73=+250 RPMs is this correct? and last would it be a good idea to get a handheld tunner at the same time, if so which one? thanks 4 da help.... its a 5spd

there is a rpm calculator in the stickies check it out. it really depends on the speeds of the freeways near you if you can keep the car to around 60 65mph they you will be fine but if they are like most around here stick with the stock gearing. the 373's wont make a huge diffence form stock (there will be some). Im like you i spend about 30 min a day on the free way doing between 70 and 80 so i am just sticking with the stockers for now.
