What a great reference you have there. Thanks. My January 93 T100 4by has the overdrive auto, ADD and supposedly, a limited slip diff. Code is A04A. Am running 16 inch tundra (02) rims with 265's in winter and they have an 8% speedometer under read. During the summer I run 20 x 8.5 inch ions with low profile 275/45r20 Ventus's. Height of the 16's is a little over 30" and the ventus's are around 29. The speedometer reading with the 20's is about 5% off. Truck is a dog but what 3.0 is not. Motor loves to run at 3 grand under load, so it does ok, just will not beat a Vega or a Pinto. But a 4K truck with a 180 inch motor should be a dog. Anyway, thanks for the link. It helps to know what is under there.
