If you deciding between the Terminator and Sniper, you may want to look at the Terminator X stealth throttle body. It sits in a middle ground in both price and function, between the Terminator and the Sniper EFI. The ECU mounts separately like the Terminator ECU. It lacks some of the IO and advanced features of the HP/Terminator ecu, but like the HP/Terminator it can still be upgraded to multiport in the future.
