By November and December of every year, aftermarket manufacturers are scurrying to get prototypes finished and press material ready in preparation for the SEMA Show in Las Vegas, and PRI Show in Orlando, FL. The fruits of their labor, as you'll see, were some very exciting new products in the GM EFI world. Some of these products may not be available for a couple of months, but they (as well as GMHTP) were eager to give you a peek at the best new products for 2008.
Fast LSX 92MM Manifold And Big Mouth Throttle Body
Fast's 90mm LSX manifold was hard to beat, and considered by most the best stock-style intake on the market. Well the best just got better, thanks to several revisions including a 92mm opening, corrosion-free stainless steel assembly bolts, and improved throttle-body sealing flange and O-ring gasket. A higher quality polymer will replace the previous construction, and FAST assures that the redesign will increase horsepower with no loss of driveability or low rpm torque. The Big Mouth throttle body increases airflow by 5% over 90mm units and takes advantage of the redesigned LSX manifold. A beefier linkage and dual throttle spring mechanism improve throttle response, also with the help of a smoother operating offset blade pivot. A thicker blade and shaft resist deflection, and its unique design is built with boosted applications in mind where throttle problems typically occur. Factory IAC and TPS sensors simply bolt up with no modification necessary.

TCI Pro-X Bolt-Together Drag Race Torque Converter
TCI's revolutionary new design allows the PRO-X Bolt-Together converter to be taken apart at the track, allowing instant stall speed adjustments. While standard converters require precision welding and balancing every time the converter is opened, TCI's unit can even be opened up for cleaning in the event of a transmission failure. A hand-built steel stator, billet sprag, and a 7075-T6 billet aluminum cover ensure reliability over 2,500 hp.
Accel DFI Thruster Efi
The Thruster EFI Engine Management System is an affordable, V/E-based system unique in its ability to operate high- or low-impedance injectors both in sequential and batch fire mode. Narrow or wideband O2 operation allows flexibility, as individual cylinder fuel control and excellent transitional fueling equate to unmatched driveability. A two-step rev limiter, controls for the torque converter lockup, A/C clutch, radiator fans, and knock are all built in. This system is said to support up to 41 psi of boost, and has special features for nitrous applications.
TCI Shift-By-Wire Shifter System
TCI's revolutionary new shifter system instantly adds a modern twist to your interior, using either a twist knob or an illuminated touch pad display for gear selection. Both are compatible with the factory electronics and TCI's own Transmission Control Unit. Each unit comes with a neutral safety and brake switch that keeps the car from being started in gear or shifted out of park without the brake being applied, just like stock. Applications are available for late-model GM transmissions, including the 700-R4 and 4L60E to 4L85E.
