1. its not the most important test to be done when putting out a part of this nature and not one that the average consumer cares about
2. i don't own a mazdaspeed3 and our sponsored client doesn't want any of the current systems on his car. we will be putting one our mazdaspeed6 with the XEDE at some point down the road.
if we go by this logic, we would need a graph for manifold plus XEDE, manifold plus CP-e standback, manifold plus ProCEDE, manifold plus Accessport..... because you are going to get people who will use one system and not the other and invalidate the results that way. at some point you have to draw the line and say "this is what the part does for your car." to even say "tuning for the manifold" really doesn't mean squat, honestly. are you tuning for what, the better exhaust flow, the faster spooling turbo, etc? these are things the factory ECU can easily learn within a drive cycle, and we've seen that on tru-boost's car. the gains you get from tuning are more than likely going to be just that - gains you get from tuning. its easily possible to take a totally stock vehicle, slap a piggyback on it and get 40 more horsepower on the car. XEDE does it for the ms3, Accessports do it for Subarus, etc etc. Its a no brainer to say that having a manifold and tune on the car is going to give you a gain. lets not forgot, how we tune the car isn't going to be identical or perhaps even close to how someone else tunes the car. so unless we're the only company selling that map for that unit with that manifold, that tuned result won't be anything to anyone other than web forum eye candy.
ok now this is ridiculous. you buy a part and blow up your car, its on you. end of story. you go buy a part from JEGS, pop your engine and tell them you are going to sue them. if you did, they'd probably hang up. its not going to be any different with me. what you do with your car is your responsibility. just like when you mod your car, blow it up and expect the magical mazda warranty to swoop down and take care of you. not going to happen. if i personally put something on your car wrong and caused it to blow up, maybe you'd have a wooden leg to stand on. maybe.
you don't need a piggyback or tuning solution for a cold air intake, a bypass valve, an exhaust system, spark plugs, down pipe, test pipe. an exhaust manifold is no different. if you needed a tuning solution for an intake or exhaust, mazda wouldn't be selling them at dealerships. its not a fragile paradigm of automotive shenanigans going on under the hood. this isn't the day or carburetors where you need to re-jet and reset them for every bolt on part. there is a reason ECUs can learn from the sensor input and are mapped the way they are. when you have a car being sold in several different climates, regions, altitudes, et al the system is going to be able to adapt for those vehicle running conditions. leaner, richer, etc the ECU is setup within a broad range to adapt to them and run perfectly fine without human intervention. i saw your argument with haltech about tuning in some other thread before it got ugly.
this is not to say you will not get the best results without tuning. you absolutely, with the right guy at the keyboard, get the best results with tuning. but your vehicle is not going to blow up from the aforementioned bolt ons and thats simple fact based in knowledge of how these cars operate, how the ECUs operate, and two plus years of these engines on the market being modded in three different platforms.
