Or you could do what im doing.
My first list of mods was your typical bolt on stuff ie: cooler,boost controller,dump pipe ect ect.
Then when i purchased the Power Fc i got the car tuned.Car runs good with no missfire or economy issue.
Im in the "second phase" of upgrades,just got a VG30 BB highflow,Profec B,Z32 AFM and poncams and Nismo injectors will arrive in the coming weeks.Once i have all the parts ill be taking the car to a tuner and getting all the mods and tune done at once.
1) It will work out a bit cheaper
2) Wont be worried about my car running rich/lean while driving it untuned.
3) I think its more rewarding to see your power level increase by leaps and bounds rather than spend a few hundred dollars on an upgrade then only seeing it only produces 5-10rwkw more.
Also there are things you can find on a road tune that you cant on a dyno.Ive had two FC tunes so far and both of them had high knock readings at some part of the rev range.These were dyno only tunes.Next tune will be a $900-$1000 job as i want my tune perfect for the setup ill have,mainly because ill be leaving the engine mods alone for a bit to concentrate on brake,sus and diff.
IMO
