Lateral loads on piles

I been looking for real and actual soil data on lateral soil subgrades modulus (Kh) to perform analyses on lateral loads on piles using programs such as: LPILE or COMP624. The program shows some typical values. But how good are these values of Kh?, what other options do I have, run a field test to measure them?
