no. best to get your own tuner. saw someone selling their DHP for $300 in the for sale section
get a wideband
best to wire it up with a guage so you can see how its working and if the controller or nozzle ever ends up not working properly and you see it go lean and be able to let off before breaking something in the motor
if you want to gain horsepower and/or use meth injection, you gotta pay to play
also alky/meth injection generally richens the overall AFR
if you want, get a tuner, injectors, and switch to e85 and it'll be more worthwhile than meth injection without all the tuning headaches
