the engine management is realy going to make or break your setup. And lets just say if it doesnt break it then it wont really make it either.
you can spend money on injectors and a new fuel pump blah blah blah but if you skimp on management you will regret it.
you say a good tuner will be able to tune it. yes they can. ask them if they recommend it. hell no. Good tuners dont like work with shit built cars. WHY? because when shit breaks it makes them look bad. The engine to start with runs a MAP sensor to calculate the fuel and timing map in the first place. Now tuning an NA engine with a tps only based piggyback has limitations. Most people will jsut tune for max load which is 100kpa in an NA engine. Now you got another 50-60kpa of load. You will have to tune very rich to bandaid the apparently problem with the AFC HACK because for the same throttle position the engine can make different boost depending on if it is going up a hill or not.
Tuning a boost car with a thottle position based air fuel controller is stupid.
Let me say that if you are going out to spend $500 on a brand new AFC Neo you are very silly. Some guys have tried to replace the tps signal with the MAP sensor signal so you can tune the engine with respect to load but it will not give you a very wide spectrum to tune for boost.
In this day and age a chipped ecu is the best way to go for Hondas.
Do it once and you will be very satisfied that your engine wont throw a rod out the block with boost it up a hill on half throttle.
If you have already made up your mind then whats the point. Good advice gone to waste.
