I just got my truck on the road.
92 SWB with a 5.3/T56 combo with a Nelson tune.
I runs great and I have everything up a running except the A/C. I still have to make some brackets.
All my gauges are working properly, except the speedo is way off.
I think the fastest its read is about 30mph.
I know it has to be recalibrated, my question is, what does it take to do it?
Maybe be an obvious answer just not sure in the hybrids.
Thanks
