The re-learn as they explain it on the Spartan website is technically for the guys/gals with the Spartan TCM. If you don't have the TCM, with the 250 tune loaded, accelerate from a stop to 65 at half throttle, do this three times. Then, from a stop, accelerate to around 70 at full throttle. Do this three times also. You will definately need to engage 4wd on the full throttle run. Just make sure you click it back off after each run. Have fun!
