i have a 190lph fuel pump on my 331 and i took it to the dyno for tuning. i do not have a WOT switch, just the window switch (yeah which was really stupid) and i did some tests. my tests were sparatic on the mustang dyno i made 424.6 power @ 4460 rpms and 499.8 Torque @ 4306 rpms. (150 shot) the tests were not clean and back fired (out of the exhaust). i have not sprayed after but when i return to the dyno i plan to have the WOT switch and the 255lph.
my question is was the backfiring because the WOT did not cut the nitrous off, and it was just continuously spraying while the car was shifting? and was the 190lph also a factor of this? because it was too small for my application?
thanks for the help in advance.

you only want to be spraying under wot.if youre letting off the gas to shift that is very dangerous.do you have the fpss on your kit.
