whats the best
i have teh apexi vafc controller, you need to have it tuned by a dyno machine to get your best results, however i have not done this yet, i have played around with it and seem to have a little more boost but i like with the vafc that you can change your vtec engagement but i would get all other mods then a vafc, due to that its betterwhen you have everything bolt on then you can tune the car better also when getting a vafc i would also get a air/fuel guage to monitior it as well
hope this helps
