I disagree. I think tuning for HARD PARTS is harder than tuning FI. All you need is "more" when it comes to FI. More boost?? Need more fuel. More fuel/boost? Need less total timing. MORE MORE MORE. That's not very definitive. N/A is more of an EXACT science (so is FI, but just for the sake of the debate) in my mind... going through 5 different headers for 3 - 4 WHP is something a lotta FI guys do not understand. What the cam card in my wallet says, they can really careless about. Throw more boost at it, and it'll work.

FI tuners really can careless what cams you are running... to them (I have spoken to a few) they are really only thinking of a few things:
--> can the block handle the boost
--> can the fuel match the psi
--> can the timing (less total timing from base) not detonate at that boost level
--> heat (run rich, less power, but cooler engine)
That's being VERY generic (not tryna knock any FI tuners), but that's basically the jist. REAL N/A tuners have to have a more intricate knowledge of ENGINES and how/why/where they make power, where a FI tuner will have a more intricate knowledge of turbo/housing/wheel selection. A lot of times even this is already done for them... you can google a compressor map for any production engine... the "recipe" is there. All you do from there is slowly up the boost, check the A/F and keep timing under control. You will not find those "recipes" for a serious N/A beast.
