Default T56 Swap Finally Finished

I have finally finished one of my main goals for my F*ing Truck. : I just totally have wrapped up my T56 swap from my 5 speed. I just finished up the last of the exhaust that needed to be reworked with the x pipe. Seen as my driveshaft snapping started this whole process and destroyed my muffler. It is amazing how shitty my truck sounded with out the same bends as it had. Truck is running great, have been through all of the gears and trying to figure out speeds due to the speedometer being off. This is what I am needing help with does anyone know how I can recalobrate? When I am shifting out of first gear, my speedometer says I am doing 35mph when I am actually doing 50mph. Second gear is 55mph and actually is 75mph. Third gear is 70mph and actually and I think I am around 105mph, but I am not sure due to the fact my Yukon shuts down at 95mph and my girlfriend couldn't keep up. I have actually already tried to change with my HP3 Tuner but, my dinosaur tuner will not compensate. Please help if you have any ideas?!

It runs great. It is a blast having all six gears. I can't believe the huge difference between this and the 5 speed. It really makes a difference with the x pipe on the exhaust; really quieted down and the tone sounds badass.


Also, I still want to know some ideas on correcting the speedometer!! I would like to know exactly what speeds I am doing, with out my girlfriend driving my Yukon next to me letting me know.
