Use this chart to compare the two axle ratios with your trans. Consider how you'll use the truck (cruise night, freeway cruising, towing) and match the ratio to your engine's torque curve.

thanks for that link
i was wondering wat rpm's my engine would run at certan legal speeds with a 4l80e and 3.73 gears
i wanted to know when its best for the chosen turbo to come on boost with that setup
that link helps a lot
it whont help driving a car on the street if the boost enters at 2000 rpm , you just be spinning out of controll in corners and all that
sumtimes a little turbolag is actually good
for street driveabillity its better to choose a bigger turbo that comes in slow and a little higher in the rpm range ..... hmmm i think thats why nelson is having so mush succes with his turbosetups
from the rpm reading per speed that turned up using that link i need the boost to come in at about 4000 rpm or so to be able to drive the truck normally without the bucking bronco effect under that rpm at highway speeds , and still have a pretty fast reaction with downshifting or pushing the trottle to over 4000 rpm
