    TPS vs MPH 7427

    95 gmc, 7427 OD tbi vortec 350. I noticed a difference between the TPS and the MPH while trying to tune a hesitation when accelerating from a stop. As soon as I touch the throttle its moving but its not showing speed on the dash for seconds after its throttled. Is it normal for this to happen?
