Other misc upgrades: (ie. cams, crank, etc): Too many mods

Tuning components (fuel management, timing, etc.): PHR MAP-ECU / Apexi AVC-R

A good Piggy-back ECU, and a good tuner mechanic and your set.....Better yet a Good Stand Alone ECU and good tuner mechanic...Although some say even a tuned piggyback will not stay in tune for long, as the stock ECU learns and changes over time...So for tuning perfection it may be an ongoing process for some....

Other misc upgrades: single ct26 57trim

Tuning components (fuel management, timing, etc.): Apexi SAFC 2

if anyone has had better luck with safc during closed loop please chime in!

how much does it cost to tune your car for na-t? how much does each map cost?

If you tune it yourself, it costs $0. Well, a few bucks here and there if u plan on re-filling your gas tank

Each MAP is self-made, so the cost of that is $0 as well.

FormosaSC

but i dont want to mess with maps... im not worthy...

Walbro, stock fuel system (USDM 550's and resistor box)

No issues whatsoever. If it's tuned correctly, AEM is the way to go.

What. In. The. Hell. Are. You. Talking. About. All I got from that statement was blah blah I don't have a clue as to what I am talking about so I'm going to make something up. Are you saying that you should only buy the program that the shop down the street can use? If so, you should refrain from posting anything else until you have read up on boosted cars for about, oh I don't know say.... 5 years? It is the exact opposite. If you are a beginner, get a basic piggy back, don't get Motech or something that is very intense and requires serious experience with the ecu itself and also the vehicle that is being tuned. You shouldn't tune your car if you don't have the basic knowledge to do so, very true, take it to a shop. However, if you attempt to build a car, and then do not have the knowledge to tune it, then you probably dont have a clue as to what the hell you are doing the first place because you don't have a true understanding of how everything is working and its purpose. Your simply bolting things up because that is what everyone else is doing. If you really know why you are doing the mod, understanding how to compensate for it in your fuel map becomes very simple. Now keep what I say in context, I am talking about simple mods here, not a 800hp meth injected twin turbo monster with 1600cc injectors. This requires hours upon hours of proper tuning to get to perfection. With a wideband, boost gauge and some simple mods, you can become familiar with the art of tuning in a short period of time with patience if you have done enough research. Statements like that just irritate the hell out of me.
