Anyone else try this combo with success? I recently installed an evo8 399 maf with Fic low z 650cc and so far its pretty dam perfect on the stock eprom ecu, no tune. It started right up and runs like stock but better. Currently at 20psi, wot afr is about 11.2, idle is perfect, cruise and mid range are also perfect. I just thought I would share that this is an awesome upgrade for 1g owners who dont have access to tuning yet. I do have supporting mods that im sure play a role in my success.
