Question NA/Nitrous Guys with DFI/Fast

I was wondering how you liked your system.
Did it smoothen everything out conciderably?
Help your times much?
How about nitrous?
I'm debating getting a system next semester...

I guess my question is what are your goals. The problem that I have seen with the DFi is difficulty in tuning. I remember speaking to Job Spetter (probably the best DFI tuner in the country) and asking him about the DFI. After speaking with him I chose to go with a Speed Pro (Fast System). Fast is supposely alot easier to tune than a DFI setup. Do you plan on tuning your own system??

yeah, that is the plan. I want to do some experimenting with different parts and knowing me, that cam will be swapped every few months just for fun
I just dont want a dyno tune ever month or two.
I would realy like to optimize with the power I can make

The problem is when you sway cams out you will have to retune the DFI regardless. Do you plan on doing your own tuning?? What kind of hp are you expecting?
