you guys might want to read the rulebook....

FUEL INJECTION
Fuel injection must retain OEM throttle body(s), plenum, and
manifold. If OEM throttle body(s) was equipped with electronic
throttle control (i.e., drive by wire), the throttle body(s) may be
adapted to mechanical throttle linkage if an aftermarket OEM-type
electronic-fuel-injection system is used. Larger fuel injectors
permitted, provided no modification or redrilling of manifolds is
performed. Electronic fuel injection must be closed, OEM-type
system; i.e., may monitor only engine functions. Monitoring of
vehicle performance criteria, wheel speed, driveshaft speed,
vehicle acceleration, etc. by fuel-injection system prohibited. All
aftermarket OEM-type electronic fuel injection must be NHRAaccepted. A current list of NHRA-accepted electronic-fuel-injection
systems is available on NHRARacer.com. Open-loop systems
permitted on production vehicles as equipped with OEM electronic
fuel injection. See General Regulations 9:1.

not saying it could be checked very easily but 99% of you are illegal running in open loop..
