a freind of mine has a 91 teg with a gsr swap. the people that did the swap are kinda shady and we dont know what injectors are in the motor the 91 ls which use a resistor box or the newer not resistor gsr ones that came with the motor. the car doesnt feel as fast as it should be when compared with other gsr swapped cars ive been in so im thinking this could have something to do with it. so i was wondering if ther is anyway to tell the diffrence between the two injectors as far a marking on them or maybe voltage at the clips?

 

youll have to measure them with a multi meter and see what resistance they are ...

low is usually around 3.00
and high is around 13.00
