I'm currently running 22 psi I have fully forged bottom end you will need gt 500 duel fuel pumps or better, kenne bell boost a pump and boost a spark at least 60 pound injectors or better...you will NEED a dyno tuner that has actually tuned kenne bell kits and or better yet the mammoth kit... I'm not going to say what parameters are soo specific but there is !!! and it takes a real educated tuner to figure it out... there for I would suggest going with a stage 2 that comes with a tune from kenne bell, is almost priceless.. you will probably end up happier and more reliable power going with the kit that comes with the tune... you asked for an opinion.. there an opinion from someone who knows and has gone through it
best of luck, let me know if ya have any more questions !
