swapped the ring and pinion out. went from 3.27's to 4.10's I got out of a explorer in a junk yard (low miles, great deal). but I also swapped my 28 splined axles to 31 splined axle (for better strength) need to know the easies way to correct the speedo?

also was wondering if any programming was need to go to 80mm MAF and marauder air box and what else as far as intake side would help with throttle response and pony's?
your help would be greatly appreciated!

You need a tune to correct the speedo and to run the larger MAF/airbox.
You can do a tune from a local tuner on a dyno or mail order like blueovalchips.com or reinhartperformance.com

I have used blueovalchips.com with good success.
I have also run HiTech Stage 2 cams with a local tuner doing the tune, the car ran great and was my daily driver. It had those cams, headers and full exhaust, larger injectors, larger TB, larger fuel pump so it could breathe in and out very well for the cams.
