Any pics of UMI Throttle Bodys?
U.M.I.'s 90mm throttle body was designed with state of the art 3D modeling software. Manufactured from A356 aircraft aluminum alloy and machined in house on the latest CNC machining centers. Featuring UMI's new parabolic throttle bore design virtually eliminates any "tip in" hesitation found in most big bore throttle bodies. Most billet straight bore throttles don't have this cut. UMI's throttle body uses the same bearings, seals, and shaft design as production throttles. This allows for a very durable design that can withstand the extreme temperature swings seen by street and racing applicaions without worrying about throttle sticking issues seen by other aftermarket throttle bodies. This throttle body is so good; it's being used exclusively by GM Racing for their racing efforts in Daytona Prototype, SCCA Road Racing, and Dakar Hummer Off-road racing.
• Precision stamped throttle cable cam.
• Double return spring for smooth throttle response and reliability.
• Parabolic throttle bore eliminates normal tip in hesitation associated with large bore diameter throttle bodies.
• Available with precision 4" wiggins O-ring groove to accept wiggins fittings on supercharged and turbo charged applications.
• Sealed roller bearings mount the stainless steel throttle shaft.
• Shaft is slit for throttle plate and shaft is locked in place to prevent plate rubbing or locking
• Countersunk screws in throttle plate allow maximum uninterrupted air flow.

That sucks about your cruise man,i got rid of my cruise control when i put my FAST rails on.The main reason i bought a UMI is for drivability,my tuner said the root of my idle problem was my PTM throttle body(it likes to open and close alot at idle).Hope you get your problem worked out...thanks for the pics!!
