i went to a shop who installed it. i am thinking it is the switch because it tested fine when he unhooked the line to the TB and the car was off. when i bypassed the switch that is the only time it worked. is there a way to test to see if this thing is working any other way. i have a 155lph fuel pump and a gague hooked up under the car. the gague never drops to 0 though, should it? (i mean after the car is off?) it says it idles at 38 psi and when i give it gas, it goes to 35. i think the gauge may be broken. do these numbers sound right?

i actually just rehooked the lines to the hobbs switch and tested it again. i may be going crazy but i think it worked in 2nd gear but couldnt tell when i shifted it into 3rd. in 2nd i punched it waited to go above 3 grand , then triggered the arming switch. it seemed to pep up a little then. i tried the sam ein third and couldnt feel a jump when i hit it, (which i think i should). i think i am just going crazy.

can i test the hobbs switch by starting the car and unhooking the line to the TB. then giving it full gas to see if it sprays?
about the 2 mustangs, this car is a LOT faster , i was talking about when hitting nitrous only! MAN, I should just go to the track and try it without a couple runs, then with it.

oh yeah i never changed the filter, the guy before me changed it about 7 thousand miles ago.
