JET ecu upgrade!! Worth It???

not sure if you any of you have done this mod, but its 399.00 to send out ur stock ecu, have them reprogram it(or they say) and u get about 10-15 hp. and i think they might take off the governor. not sure. id much rather just have somone tune it to what i want, but dont know ppl that do that. but i am in phx, so if anyone knows hit me up.
