I'm not sure how fast the Titan is, but you should be able to blow him out of the water with an Edge Juice with Attitude. You should only need level 3 to do it. Actually you probably only need about a 40 or 60 hp tune to really wake up your truck. Have you checked what his quarter mile time is according to a site like car and driver? Really it should be a no contest even with you in stock form. Although, I don't know much about the Titan, so I don't want to mislead you. I have gone against different vehicles in traffic and you know how people like to "race" you to the next stoplight? Well, in the summer I normally run about a 45 hp tune over stock and I blow them away without even trying. I am only at half throttle and I just pull away from most vehicles.
