Tech Guide Question

mr ginzo said:

alright i was reading the tech guide for stage II: http://www.evotuners.net/tuning-guide/stage2power.php



lets say i'd have:
"stage 1" plus
Intake Pipe (MAF Pipe), Cams, Larger FMIC and an Exhaust Manifold. Now im pretty satisfied with this and im done modding my car. what should i do for fuel? i know the last step is injectors ect..but is a Fuel Pump, Injectors,FPR, and a Fuel Rail all nessescary if im done modding, or could i get away with just a FPR or injectors...


Also, if i want to ditch my AFC is there a company that can "flashload" a map for my mods into my ECU and just run no AFC?

Pretty easy answers here. The first thing is you have several mods that aren't needed or recommended on the stock turbo (FMIC/MAF pipe), but if you already have them, we can work around them.

1) You should have had a fuel pump way before any of those mods. If you don't already have one, then get one RIGHT NOW. You are in possible danger EVERY DAY you drive with all those mods on the stock fuel pump. There is absolutely no need for all those other fuel items, though. Upgraded injectors aren't needed on the stock turbo, and the FPR + fuel rail aren't even usually mentioned until people have done major upgrades.

2) Yes, of course there are flash tuners who can flash your ECU. That's the most common form of tuning there is for the Evo. The SAFC is the most crude and limited tuning device. I have been successful with both a flash and an SAFC, but I have gotten much bigger gains from the flash. Hell, having a flash plus the SAFC for fine tuning (especially on race gas) is a great combo, too. You could sell your SAFC and get flashed through the mail or in person with a custom road or dyno tune from any of the flash tuners. My preference is Dynoflash. I ran a 12.26 on 93oct with a mail-in Dynoflash without any of the mods you listed above.
