yea its a great kit but it does not come with a 125 jet. it has 50 jets,100,150,200,250,300. some people say the 100 jets on the NX systems are equal to a NOS 125 jet. Just because the power is rated to the wheels.
thats the best with the plate kit. but i also had extremely bald street tires lol. and if you have ever used nitrous before bald tires + nitrous = wheel spin like crazy. but it added about 8mph to my traps on a 100 shot.
also i started spraying halfway through 2nd gear and then in 3rd. couldnt spray at the beginning of 2nd because when i grabbed 2nd hard after first i would spin the wheels for a good second or so. and i had to wait for it to grab before hitting it.
