You need to learn to pedal at a higher cadence.
Your bike likely has a 50/34 crank, and a 12-25 rear cassette (current spec for a Trek 1.1) That gets you to 29mph at 90 rpm, 33mph at 100 rpms, and almost 40 mph at 120 rpm.
90 rpm is a reasonable cruising cadence, 100 rpm is also reasonable particualrly when your hammering, and 120 rpm is a typical sprinting cadence.
You're not being held back by your gearing. On the off chance you can sustain 33mph on flat gorund without a killer tailwind, for a sustained period of time, your team mechanic should be taking care of your selection of bottom brackets.
All that said,if you must have a higher gear, going to an 11-23 or 11-25 cassette woul be cheaper and easier.
